CUSTOMER DATA ACCESS AND PRIVACY 4025. Scope and Applicability.

(a) The basis and purpose of these rules is to describe the protection of and limited access to customer data for gas utilities over which the Commission has jurisdiction. These rules are applicable to all utilities except for certain provisions as defined in the rule.

(b) For the purpose of the Customer Data Access and Privacy Rules, gas utilities are classed into three tiers: a Tier I utility serves more than 150,000 gas customers; a Tier II utility serves between 50,000 and 150,000 gas customers. A Tier III utility serves fewer than 50,000 gas customers.

(c) No Tier III utility is required to:

(I) include in its tariffs a description of standard and non-standard customer data that the utility is able to provide to the customer or to any third party recipient (see paragraph 4027(c));

(II) provide customer notice each year regarding customer data (see rule 4028);

(III) make customer consent forms for the disclosure of customer data available to customers or third parties (see rule 4029); (IV) disclose aggregated data (see rule 4033); or (V) provide a community energy report (see rule 4035).

However, a Tier III utility may include a description of standard and non-standard customer data that the utility is able to provide to the customer or to any third- party recipient in its tariffs (in accordance with paragraph 4027(c)). Commencing upon the effective date of such description, the Tier III utility shall be deemed to be a Tier II utility for purposes of these Customer Data Access and Privacy Rules for so long as such tariff provisions remain in effect. 21 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4026. Customer Data.

(a) A utility shall maintain standard customer data sufficient to allow a customer to understand his or her energy usage at a level of detail commensurate with the metering technology used to serve the customer.

4027. Privacy, Access, and Disclosure.

(a) A utility shall protect customer data in the utility’s possession or control to maintain the privacy of customers, while providing reasonable access to that data. A utility is only authorized to use customer data to provide regulated utility service in the ordinary course of business.

(b) A utility shall not disclose customer data unless such disclosure conforms to these rules, except as required by law or to comply with Commission rule. Illustratively, this includes responses to requests of the Commission, warrants, subpoenas, court orders, or as authorized by § 16-15.5-102, C.R.S. (c) A utility shall include in its tariffs a description of customer data that the utility is able to provide to the customer or to any third party recipient to whom the customer has authorized disclosure of the customer’s data within the utility’s technological and data capabilities. At a minimum, the utility’s tariff must provide the following:

(I) a description of standard customer data and non-standard customer data and the frequency of customer data updates that will be available (annual, monthly, daily, etc.);

(II) the method and frequency of customer data transmittal and access available (electronic, paper, etc.) as well as the security protections or requirements for such transmittal;

(III) a timeframe for processing requests;

(IV) any rate associated with processing a request for non-standard customer data; and (V) any charges associated with obtaining non-standard customer data. (d) As part of basic utility service, a utility shall provide access to the customer’s standard customer data in electronic machine-readable form, without additional charge, to the customer or to any third party recipient to whom the customer has authorized disclosure of the customer’s customer data. Such access shall conform to nationally recognized open standards and best practices. The utility shall provide access in a manner that ensures adequate protections for the utility’s system security and the continued privacy of the customer data during transmission.

22 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (e) Nothing in these rules shall limit a customer’s right to provide his or her customer data to anyone.

(f) A utility and each of its directors, officers and employees that discloses customer data pursuant to a customer’s authorization in accordance with these data privacy rules shall not be liable or responsible for any claims for loss or damages resulting from the utility’s disclosure of customer data. 4028. Customer Notice.

(a) A utility shall provide each year to its customers a written notice complying with this rule. The utility shall conspicuously post on its website notice of its privacy and security policies governing access to and disclosure of customer data and aggregated data to third-parties. This notice shall:

(I) explain what is available to customers, as standard and/or non-standard customer data (e.g., daily versus hourly data);

(II) describe the frequency that the utility can provide customer data based on a request for standard data (e.g., on a weekly or monthly basis); (III) advise customers that their customer data may provide insight into their activities within the premises receiving service;

(IV) inform customers that the privacy and security of their customer data will be protected by the utility while in its possession;

(V) explain that customers can access their standard customer data, as identified by the utility’s tariff, without additional charge; (VI) advise customers that their customer data will not be disclosed to third parties, except:

(A) as necessary to provide regulated utility services to the customers; (B) as otherwise permitted or required by law or Commission rule; or (C) pursuant to the authorization given by the customer in accordance with these rules.

(VII) describe the utility’s policies regarding how a customer can authorize access and disclosure of their customer data to third-parties. With regard to such third party data disclosure, the notice shall:

23 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (A) inform customers that declining a request for disclosure of customer data to a third party will not affect the provision of utility service that the customer receives from the utility; and (B) explain that any customer consent for access to, disclosure of, or use of a customer’s customer data by a third party may be terminated or limited by the customer of record at any time and inform the customers of the process for doing so.

(VIII) explain that aggregated data does not contain customer identifying information and inform customers that customer data may be used to create aggregated data that will not contain customer identifying information;

(IX) explain that the utility may provide aggregated data to third-parties, subject to its obligation under paragraph 4033(a);

(X) be viewable on-line and printed in ten point or larger font; (XI) be sent either separately or included as an insert in a regular monthly bill, or, for those customers who have consented to receive e-bills, such notice may be sent electronically separately from an e-bill, conspicuously marked and stating clearly that important information on the utility’s privacy practices is contained therein;

24 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (XII) be available in English and Spanish. The customer notice may also be translated to a language other than English or Spanish by a third party or the utility. Forms translated to other languages in accordance with this rule must be accepted by utilities, and may be relied upon, after the English version of the form, the translated version of the form, and an affidavit attesting to the accurate and complete translation from the English version of the form, have been provided to the Commission and the utility possessing the data. Such affidavit must be executed by an interpreter on the active roster of interpreters maintained by the Office of Language Access of the Colorado Judicial Branch. If the utility incurs a cost for translation made at the request of a third party, it may charge the requestor for such cost and may include a reasonable administrative fee in addition to the translation cost; and (XIII) provide a customer service phone number and web address where customers can direct additional questions or obtain additional information regarding their customer data, the disclosure of customer data or aggregated data, or the utility’s privacy policies and procedures with respect to customer data or aggregated data.

4029. Customer Consent Form for the Disclosure of their Customer Data to Third Party Recipients by a Utility.

(a) A utility shall make available to any third party a consent form for the disclosure of customer data that is maintained by the Commission and available from the Commission’s website. The form shall be available electronically from the utility. The consent form shall be provided in a non-electronic format by a utility upon request from a customer or third party.

(b) In addition to the Commission supplied form, a utility may create and make available a consent form that:

(I) includes the same information contained in the annual notice provided under subparagraphs 4028(a)(V), (VI), (VII), and (XIII); (II) provides spaces for the following required information regarding the third party recipient of the customer data:

(A) the name, including trade name if applicable, physical address, mailing address, e-mail address, and telephone number;

(B) the uses of the data for which the customer is allowing disclosure; (C) the time period (e.g., months, years) for which data are being requested; and (D) the description of the data that are being requested; 25 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (III) states that the consent is valid until terminated; (IV) states that the customer must notify the utility service provider in writing (electronically or non-electronically) to terminate the consent including appropriate utility contact information;

(V) states any additional terms except an inducement for the customer’s disclosure;

(VI) be viewable on-line and printed in ten point or larger font; and (VII) provides notice to the customer that the utility shall not be responsible for monitoring or taking any steps to ensure that the third party to whom the data is disclosed is maintaining the confidentiality of the data or using the data as intended by the customer.

(c) A utility may make available an electronic customer consent process for disclosure of customer data to a third party (e.g., a utility controlled web portal) that authenticates the customer identity. The contents of the electronic consent process must generally follow the format of the model consent to disclose customer data form, be clear, and include the elements to be provided pursuant to paragraph (a) of this rule. No utility is required to provide an electronic consent process in a language other than English.

(d) A utility may make available an in-person consent process for disclosure of customer data.

(e) A consent form may be submitted to the utility through electronic or non- electronic methods.

(f) The scope of consent given shall be defined by the terms of the consent form, except that changes of contact names for an organization, trade name, or utility over time do not invalidate consent as to the respective organization, trade name, or utility. Because the contact named for an organization, trade name, or utility is a representative of the respective organization, trade name, or utility, consent terminates as to such contact when the relationship with the organization, trade name, or utility terminates. Modifications to the consent form over time do not invalidate previous consent. Consent need not be provided on a new form so long as the data provided remains within the scope of consent. 26 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (g) Customer consent forms shall be available in English and Spanish. Customer consent forms may be translated to into languages other than English or Spanish by a third party or the utility. Forms translated to other languages in accordance with this rule must be accepted by utilities, and may be relied upon, after the English version of the form, the translated version of the form, and an affidavit attesting to the accurate and complete translation from the English version of the form, have been provided to the Commission and the utility possessing the data. Such affidavit must be signed by an interpreter on the active roster of interpreters maintained by the Office of Language Access of the Colorado Judicial Branch. If a utility incurs a cost for a translation at the request of a third party, it may charge the requestor for such cost and may include a reasonable administrative fee in addition to the translation cost.

(h) Any customer consent forms available from the Commission’s website shall be presumed to comply with these rules.

4030. Access to Customer Data for the Provision of Regulated Utility Service. (a) A utility may disclose customer data to a contracted agent provided that the contract requires the agent to:

(I) implement and maintain data security procedures and practices to protect the customer data from unauthorized access, destruction, use, modification, or disclosure that are equal to or greater than the data privacy and security policies and procedures used by the utility internally to protect customer data;

(II) use customer data solely for the purpose of the contract and prohibits the use of customer data for a secondary commercial purpose not related to the purpose of the contract without first obtaining the customer’s consent as provided for in these rules;

(III) return to the utility or destroy any customer data that is no longer necessary for the purpose for which it was transferred; and (IV) execute a non-disclosure agreement with the utility. (b) The utility shall maintain records of the disclosure of customer data to contracted agents for a minimum of three years. Such records shall include all contracts with the contracted agent and executed non-disclosure agreements. 27 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4031. Local Government Access to Customer Data from a Utility for Audit. (a) A utility may disclose customer data to a local government either with an audit required to be provided pursuant to a final Commission decision (e.g., a decision approving a franchise agreement) or as reasonably necessary for an audit conducted by a governmental entity of franchise fees paid to them by the utility, provided that:

(I) disclosure is not otherwise prohibited by a final Commission decision (e.g., Commission-approved franchise between the utility and the local government);

(II) disclosure is made to a designated auditor or auditor’s office, who is either an employee or agent of the local government;

(III) the auditor collects and uses the customer data solely for the purpose of reviewing or conducting the audit and is prohibited from disclosing or using the customer data for a purpose not related to the audit; (IV) the local government implements and maintains data security procedures and practices to protect the customer data from unauthorized access, destruction, use, or modification;

(V) the local government destroys or returns to the utility of any customer data no longer necessary for the purpose for which it was transferred unless state law or the municipality’s state-mandated retention schedule requires otherwise;

(VI) the local government agrees not to permit access to the data by anyone that has not agreed to abide by the terms pursuant to which the data was provided by the utility. This includes, but is not limited to, all interns, subcontractors, staff, other workforce members, and consultants; (VII) the local government agrees that any recipient of the data pursuant to this rule does not obtain any right, title or interest in any of the data provided by the utility;

(VIII) governing law or a non-disclosure agreement executed with the utility requires that the local government, at a minimum, comply with the requirements of this rule; and (IX) the data requested is for utility customers served in the boundaries of the local government.

(b) The utility shall maintain records of all disclosures of customer data to local government requestors for a minimum of three years.

28 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (c) Availability of customer data pursuant to this rule does not preclude a local government from requesting other data reports.

4032. Third Party Access to Customer Data from a Utility. (a) Except as provided in this rule, paragraph 4027(b), rule 4030, and rule 4031, a utility shall not disclose customer data to any third party unless the customer or a third party acting on behalf of a customer submits a paper or electronic signed consent to disclose customer data form that has been executed by the customer of record.

(b) Incomplete or non-compliant consent to disclose customer data forms are not valid and shall be rejected by the utility.

(c) The utility shall maintain records of all of the disclosures of customer data to third party requestors. Such records shall include a copy of the customer’s signed consent to disclose customer data form, all identifying documentation produced by the third party requestor, the customer's agreed upon terms of use, the date(s) and frequency of disclosure, and a description of the customer data disclosed. (d) The utility shall maintain records of customer data disclosures for a minimum of three years and shall make the records of the disclosure of a customer’s customer data available for review by the customer within five business days of receiving a paper or electronic request from the customer, or at such greater time as is mutually agreed between the utility and the customer. 4033. Requests for Aggregated Data Reports from a Utility. (a) A utility shall not disclose aggregated data unless the recipient is authorized to receive all customer data within the aggregated data, and the disclosure otherwise conforms to this rule and rules 4031, 4034, and 4035. In aggregating customer data to create an aggregated data report, a utility must ensure that the data do not include any personal information or a unique identifier. (b) At a minimum, a particular aggregation must contain at least fifteen customers; and, within any customer class no single customer’s customer data or premise associated with a single customer’s customer data may comprise 15 percent or more of the total customer data aggregated per customer class to generate the aggregated data report (the “15/15 Rule”).

29 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (c) If an aggregated data report cannot be generated in compliance with paragraph 4033(b), the utility shall notify the requestor that the aggregated data, as requested, cannot be disclosed and identify the reason(s) the request was denied. The requestor shall be given an opportunity to revise its aggregated data request in order to address the identified reason(s). An aggregated data request may be revised by expanding the number of customers or premise accounts in the request, expanding the geographic area included in the request, combining different customer classes or rate categories, or other applicable means of aggregating.

(d) A utility shall include in its tariffs a description of standard and non-standard aggregated data reports available from the utility to any requestor. At a minimum, the utility’s tariff shall provide the following:

(I) a description of standard and non-standard aggregated data reports available from the utility including all available selection parameters (customer data or other data);

(II) the frequency of data collection (annual, monthly, daily, etc.); (III) the method of transmittal available (electronic, paper, etc.) and the security protections or requirements for such transmittal; (IV) the charge for providing a standard aggregated data report or the hourly charge for compiling a non-standard aggregated data report; (V) the timeframe for processing requests; and (VI) a request form for submitting a data request for aggregated data reports to the utility identifying any information necessary from the requestor in order for the utility to process the request.

(e) If a utility is unable to fulfill a non-standard aggregated data report request because it does not have and/or does not elect to or cannot obtain all of the data the requestor wishes to include in the aggregated data report, then the utility may contract with a contracted agent to include the additional data and process it along with the customer data in the utility’s possession, to generate a non- standard aggregated data report.

(f) A utility and each of its directors, officers and employees that discloses aggregated data as provided in these data privacy rules shall not be liable or responsible for any claims for loss or damages resulting from the utility’s disclosure of aggregated data.

(g) A utility shall not provide aggregated customer data in response to multiple overlapping requests from or on behalf of the same requestor that have the potential to identify customer data.

30 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4034. Property Owner Request for Whole Building Energy Use Data from a Utility. (a) If requested by a property owner or its authorized agent, a Tier I utility shall provide whole building energy use data to the property owner or its authorized agent so long as:

(I) the whole building energy use data contains at least four customers or tenants, which may include the property owner’s own account; and no single customer’s customer data, unless it is the property owner’s, comprises more than 50 percent of the whole building energy use data used to generate the whole building energy use data report; (II) the property owner or its authorized agent agrees to not disclose the whole building energy use data except for the purposes of building benchmarking, identifying energy efficiency projects, and energy management; and (III) the property owner or its authorized agent signs a non-disclosure agreement with the utility requiring the property owner, at a minimum to: (A) take appropriate administrative, technical, and physical safeguards to protect the whole building data from any unauthorized use or disclosure to protect the data from unauthorized access, destruction, use, modification, or disclosure;

(B) only use the whole building data only for the purposes of building benchmarking, identifying energy efficiency projects, energy management, and complying with laws or ordinances;

(C) agree not to attempt to determine an individual utility customer’s energy use from the whole building data and not to use the information to contact the subject of the information;

(D) agree not to use the whole building energy use data for a secondary commercial purpose not related to the authorized purpose without first obtaining the customer’s consent as provided for in these rules;

(E) destroy any whole building energy use data that is no longer necessary for the purpose for which it was transferred; (F) agree not to permit access to the whole building data by anyone that has not agreed to abide by the terms pursuant to which the data was provided by the utility. This includes, but is not limited to, all interns, subcontractors, staff, other workforce members, and consultants; and 31 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (G) agree that any recipient of the whole building data pursuant to this rule does not obtain any right, title or interest in any of the data provided by the utility.

(b) Upon request by a property owner or its authorized agent, a Tier II utility shall provide whole building energy use data upon the same conditions to the extent of, and based upon, information available in the ordinary course of business. (c) A utility shall provide a requested whole building energy use data report in electronic, machine readable format that conforms to nationally recognized open standards and best practices.

(d) A utility may charge a property owner or its authorized agent for the development of a whole building energy use data report. Such rate shall be determined in a utility tariff as a non-standard aggregated data report. Alternatively, the utility need not charge the customer if the cost to charge a property owner or its authorized agent is greater than the cost to develop a whole building energy use data report.

(e) Availability of whole building energy use data pursuant to this rule does not preclude a property owner from requesting other data reports. 4035. Community Energy Reports.

(a) A Tier I utility shall generate a community energy report for each local government other than a Colorado county included in its service territory with 50,000 or more residents. A Tier I utility shall generate a community energy report for each Colorado county included in its service territory with 100,000 or more residents. Any local government with fewer than 50,000 residents and Colorado county with fewer than 100,000 residents or a minority of whom are served by a Tier I utility shall be treated as if it had 50,000 or more residents served by the Tier I upon request from the local government or county. Such requests shall be made by January 31 of the calendar year following the reporting year and shall continue in effect until such time as the request is withdrawn or cancelled by the local government. All population thresholds shall be based on the most recent population estimate from the Colorado State Demography Office and where the utility serves the majority of the population. (b) On or before June 1 of every year, a Tier I utility shall make publicly available for download all community energy reports generated for the prior year.

BILLING AND SERVICE 4400. Applicability.

Rules 4400 through 4412 apply to residential customers, small commercial customers and agricultural customers served pursuant to a LDC’s rates or tariffs. Rules 4400 70 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission through 4405 and rules 4407 through 4412 shall not apply to customers served under a LDC’s transportation rates or tariffs. In its tariffs, a LDC shall define “residential,” “small commercial” and “agricultural” customers to which these rules apply. The LDC may elect to apply the same or different terms and conditions of service to other customers. 4401. Billing Information and Procedures.

(a) All bills issued to customers for metered service furnished shall show: (I) the dates and meter readings beginning and ending the period during which service was rendered;

(II) an appropriate rate or rate code identification for each separate rate component charged to the bill. Each component shall be designated on the bill in a manner such that the rate or charge can be identified clearly when referencing approved rates found in the utility’s tariff; (III) the net amount due for regulated charges;

(IV) the date by which payment is due, which shall not be earlier than 15 days after the mailing or the hand-delivery of the bill;

(V) a distinct marking to identify an estimated bill;

(VI) the total amount of all payments or other credits made to the customer’s account during the billing period;

(VII) any past due amount. Unless otherwise stated in a tariff or Commission rule, an account becomes “past due” on the 31st day following the due date of current charges;

(VIII) the identification of, and amount due for, unregulated charges, if applicable;

(IX) any transferred amount or balance from any account other than the customer’s current account; and (X) all other essential facts upon which the bill is based, including factors and constants, as applicable.

(b) A utility that bills for unregulated services or goods shall allocate partial payments first to regulated charges and then to unregulated charges or non-tariff charges and to the oldest balance due separately within each category. (c) A utility that transfers to a customer a balance from the account of a person other than that customer shall have in its tariffs the utility’s benefit of service transfer policies and criteria. The tariffs shall contain an explanation of the process by 71 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission which the utility will verify, prior to billing a customer under the benefit of service tariff, that the person to be billed in fact received the benefit of service. (d) A utility may transfer a prior unpaid debt to a customer’s bill if the prior bill was in the name of the customer and the utility has informed the customer of the transferred amount and of the source of the unpaid debt (for example, and without limitation, the address of the premises to which service was provided and the period during which service was provided).

(e) If it is offered in a tariff, upon request from a customer and where it is technically feasible, a utility may have the option to provide electronic billing (e-billing), in lieu of a printed bill, to the requesting customer. If a utility offers the option of e- billing, the following shall apply:

(I) the utility shall obtain the affirmative consent of a customer to accept such a method of billing in lieu of printed bills;

(II) the utility shall not charge a fee for billing through the e-billing option; (III) the utility shall not charge a fee based on customer payment options that is different from the fee charged for the use of the same customer payment options by customers who receive printed bills; and (IV) a bill issued electronically shall contain the same disclosures and Commission-required information as those contained in the printed bill provided to other customers.

4402. Adjustments for Meter and Billing Errors.

(a) A utility shall adjust a customer’s bill(s) for gas incorrectly metered or billed as follows.

(I) When, upon any meter accuracy test, a meter is found to be running slow in excess of error tolerance levels allowed under rule 4302, the utility may charge for one-half of the under-billed amount for the period dating from the discovery of the meter error back to the previous meter test, with such period not to exceed six months.

72 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (II) When, upon any meter accuracy test, a meter is found to be running fast in excess of error tolerance levels allowed under rule 4302, the utility shall refund one-half of the excess charge for the period dating from the discovery of the meter error back to the previous meter test, with such period not to exceed two years.

(III) When a meter does not register, registers intermittently, or partially registers for any period, the utility may estimate, using the method stated in its tariff, a charge for the gas used based on amounts metered to the customer over a similar period in previous years. The period for which the utility charges the estimated amount shall not exceed six months. (IV) In the event of under-billings not provided for in subparagraph (a)(I) or (III) of this rule (such as, but not limited to, an incorrect multiplier, an incorrect register, or a billing error), the utility may charge for the period during which the under-billing occurred, with such period not to exceed six months.

(V) In the event of over-billings not provided for in subparagraph (a)(II) of this rule, the utility shall refund for the period during which the over-billing occurred, with such period not to exceed two years.

(b) The periods set out in paragraph (a) of this rule shall commence on the earliest date on which either the customer notifies the utility or the utility notifies the customer of a meter or billing error, the customer informs the utility of a billing or metering error, or a dispute based on a billing or metering error, or the customer submits an informal complaint to the Consumer Assistance Unit of the Commission. http://www.colorado.gov/pacific/dora/file-consumer-complaint. (c) In the event of an over-billing, the customer may elect to receive the refund as a credit to future billings or as a one-time payment. If the customer elects a one- time payment, the utility shall make the refund within 30 days. Such over-billings shall not be subject to interest.

(d) In the event of under-billing, the customer shall be eligible and may elect to enter into a payment arrangement on the under-billed amount. The payment arrangement shall be equal in length to the length of time during which the under- billing occurred. Such under-billings shall not be subject to interest. 73 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4403. Applications for Service, Customer Deposits, and Third-Party Guarantee Arrangements.

(a) A utility shall process an application for utility service that is made either orally or in writing and shall apply nondiscriminatory criteria with respect to the requirement of a deposit prior to commencement of service. Nondiscriminatory criteria means that no deposit or guarantee, or additional deposit or guarantee, shall be required by a utility because of race, sex, creed, national origin, marital status, age, number of dependents, source of income, disability, or geographical area of residence.

(b) All utilities requiring deposits shall offer customers at least one payment alternative that does not require the use of the customer’s social security number.

(c) If billing records are available for a customer who has received past service from the utility, the utility shall not require that person to make new or additional deposits to guarantee payment of current bills unless the records indicate recent or substantial delinquencies.

(d) A utility shall not require a deposit from an applicant for service who provides written documentation of a 12 consecutive month good payment history from the utility from which that person received similar service. For purposes of this paragraph, the 12 consecutive months must have ended no earlier than 60 days prior to the date of the application for service.

(e) A utility shall not require a deposit from an applicant for service or restoration of service who is or was within the last 12 months, a participant in the Low-Income Energy Assistance Program or in an income qualified program consistent with rule 4412, or who received energy bill assistance from Energy Outreach Colorado within the last 12 months.

(f) If a utility uses credit scoring to determine whether to require a deposit from an applicant for service or a customer, the utility shall have a tariff that describes, for each scoring model that it uses, the credit scoring evaluation criteria and the credit score limit that triggers a deposit requirement. (g) If a utility uses credit scoring, prior payment history with the utility, or customer- provided prior payment history with a like utility as a criterion for establishing the need for a deposit, the utility shall include in its tariff the specific evaluation criteria that trigger the need for a deposit.

74 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (h) If a utility denies an application for service or requires a deposit as a condition of providing service, the utility immediately shall inform the applicant for service of the decision and shall provide, within three business days, a written explanation to the applicant for service stating the specific reasons why the application for service has been denied or a deposit is required.

(i) No utility shall require any surety other than either a deposit to secure payment for utility services or a third-party guarantee of payment in lieu of a deposit. In no event shall the furnishing of utility services or extension of utility facilities, or any indebtedness in connection therewith, result in a lien, mortgage, or other interest in any real or personal property of the customer unless such indebtedness has been reduced to a judgment. Should the guarantor terminate service or terminate the third party guarantee before the customer has established a satisfactory payment record for 12 consecutive months, the utility, applying the criteria contained in its tariffs, may require a deposit or a new third party guarantor. (j) The total deposit a utility may require or hold at any one time shall not exceed an amount equal to an estimated 90 days' bill of the customer, except in the case of a customer whose bills are payable in advance of service, in which case the deposit shall not exceed an estimated 60 days' bill of the customer. The deposit may be in addition to any advance, contribution in aid of construction or guarantee required by the utility tariff in connection with construction of lines or facilities, as provided in the extension policy in the utility's tariffs. A deposit may be paid in installments.

(k) A utility receiving deposits shall maintain records showing: (I) the name of each customer making a deposit;

(II) the amount and date of the deposit;

(III) each transaction, such as the payment of interest or interest credited, concerning the deposit;

(IV) each premise where the customer receives service from the utility while the deposit is retained by the utility;

(V) if the deposit was returned to the customer, the date on which the deposit was returned to the customer; and (VI) if the unclaimed deposit was paid to the energy assistance organization, the date on which the deposit was paid to the energy assistance organization.

(l) Each utility shall state in its tariff its customer deposit policy for establishing or maintaining service. The tariff shall state the circumstances under which a deposit will be required and the circumstances under which it will be returned. A 75 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission utility shall return any deposit paid by a customer who has made no more than two late payments in 12 consecutive months.

(m) Each utility shall issue a receipt to every customer from whom a deposit is received. No utility shall refuse to return a deposit or any balance to which a customer may be entitled solely on the basis that the customer is unable to produce a receipt.

(n) The payment of a deposit shall not relieve any customer from the obligation to pay current bills as they become due. A utility is not required to apply any deposit to any indebtedness of the customer to the utility, except for utility services due or past due after service is terminated.

(o) A utility shall pay simple interest on a deposit at the percentage rate per annum as calculated by the Commission staff and in the manner provided in this paragraph.

(I) At the request of the customer, the interest shall be paid to the customer either on the return of the deposit or annually. The simple interest on a deposit shall be earned from the date the deposit is received by the utility to the date the customer is paid. At the option of the utility, interest payments may be paid directly to the customer or credited to the customer's account.

(II) The simple interest to be paid on a deposit during any calendar year shall be at a rate equal to the average for the period October 1 through September 30 (of the immediately preceding year) of the 12 monthly average rates of interest expressed in percent per annum, as quoted for one-year United States Treasury constant maturities, as published on the website or publication of the Board of Governors of the Federal Reserve System. Each year, the Commission staff shall compute the interest rate to be paid. If the difference between the existing customer deposit interest rate and the newly calculated customer deposit interest rate is less than 25 basis points, the existing customer deposit interest rate shall continue for the next calendar year. If the difference between the existing customer deposit interest rate and the newly calculated customer deposit interest rate is 25 basis points or more, the newly calculated customer deposit interest rate shall be used. The Commission shall send a letter to each utility stating the rate of interest to be paid on deposits during the next calendar year. Annually following receipt of Commission staff’s letter, if necessary, a utility shall file by advice letter or application, as appropriate, a revised tariff, effective the first day of January of the following year, or on an alternative date set by the Commission, containing the new rate of interest to be paid upon customers’ deposits, except when there is no change in the rate of interest to be paid on such deposits. 76 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (p) A utility shall have tariffs concerning third-party guarantee arrangements and, pursuant to those tariffs, shall offer the option of a third party guarantee arrangement for use in lieu of a deposit. The following shall apply to third-party guarantee arrangements:

(I) an applicant for service or a customer may elect to use a third-party guarantor in lieu of paying a deposit;

(II) the third-party guarantee form, signed by both the third-party guarantor and the applicant for service or the customer, shall be provided to the utility;

(III) the utility may refuse to accept a third-party guarantee if the guarantor is not a customer in good standing at the time of the presentation of the guarantee to the utility;

(IV) the amount guaranteed shall not exceed the amount which the applicant for service or the customer would have been required to provide as a deposit;

(V) the guarantee shall remain in effect until the earlier of the following occurs: (A) the guarantee is terminated in writing by the guarantor; (B) if the guarantor was a customer at the time of undertaking the guarantee, the guarantor ceases to be a customer of the utility; or (C) the customer has established a satisfactory payment record, as defined in the utility's tariffs, for 12 consecutive months. (VI) Should the guarantor terminate service or terminate the third party guarantee before the customer has established a satisfactory payment record for 12 consecutive months, the utility, applying the criteria contained in its tariffs, may require a deposit or a new third party guarantor.

77 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (q) A utility shall pay all unclaimed monies, as defined in § 40-8.5-103(5), C.R.S., that remain unclaimed for more than two years to the energy assistance organization. “Unclaimed monies” shall not include: undistributed refunds for overcharges subject to other statutory provisions and rules and credits to existing customers from cost adjustment mechanisms.

(I) Monies shall be deemed unclaimed and presumed abandoned when left with the utility for more than two years after termination of the services for which the deposit or the construction advance was made or when left with the utility for more than two years after the deposit or the construction advance becomes payable to the customer pursuant to a final Commission order establishing the terms and conditions for the return of such deposit or advance and the utility has made reasonable efforts to locate the customer.

(II) Interest on a deposit shall accrue at the rate established pursuant to paragraph (o) of this rule commencing on the date on which the utility receives the deposit and ending on the date on which the deposit is paid to the energy assistance organization. If the utility does not pay the unclaimed deposit to the energy assistance organization within four months of the date on which the unclaimed deposition is deemed to be unclaimed or abandoned pursuant to subparagraph (q)(I) of this rule, then at the conclusion of the four-month period, interest shall accrue on the unclaimed deposit at the rate established pursuant to paragraph (o) of this rule plus six percent.

(III) If payable under the utility’s line extension tariff provisions, interest on a construction advance shall accrue at the rate established pursuant to paragraph (o) of this rule commencing on the date on which the construction advance is deemed to be owed to the customer pursuant to the utility’s extension policy and ending on the date on which the construction advance is paid to the energy assistance organization. If the utility does not pay the unclaimed construction advance to the energy assistance organization within four months of the date on which the unclaimed construction advance is deemed to be unclaimed or abandoned pursuant to subparagraph (q)(I) of this rule, then at the conclusion of the four-month period, interest shall accrue on the unclaimed construction advance at the rate established pursuant to paragraph (o) of this rule plus six percent.

(r) A utility shall resolve all inquiries regarding a customer’s unclaimed monies and shall not refer such inquiries to the energy assistance organization. (s) If a utility has paid unclaimed monies to the energy assistance organization, a customer later makes an inquiry claiming those monies, and the utility resolves the inquiry by paying those monies to the customer, the utility may deduct the 78 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission amount paid to the customer from future funds submitted to the energy assistance organization.

4404. Charges, Fees, and Payment Plans.

(a) In its tariffs, a utility shall provide a description of all charges or fees that the utility assesses resulting from regulated charges that are past due and service discontinuance and restoration. A utility may assess the following charges or fees at no higher than cost, as stated in its tariff:

(I) a late payment charge for regulated charges that are past due and exceed $50;

(II) a fee for discontinuance of service;

(III) a fee for restoration of service;

(IV) collection fees; and (V) any other regulated charges or fees provided in the utility’s tariff. (b) In its tariffs, a utility shall have the following payment plans available for its customers:

(I) an installment payment plan; and (II) a budget or level payment plan.

(c) A utility shall have in its tariff an installment payment plan which permits a customer to make installment payments if one of the following applies. (I) The plan is to pay regulated charges from past billing periods and the past due amount arises solely from events under the utility’s control (such as, without limitation, meter malfunctions, billing errors, utility meter reading errors, or failures to read the meter, except where the customer refuses to read the meter and it is not readily accessible to the utility). A utility shall advise a customer who is eligible for this type of plan of the customer's eligibility. At the request of the customer and at the customer's discretion, an installment payment plan under this subparagraph shall extend over a period equal in length to that during which the errors were accumulated and shall not include interest.

79 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (II) The customer pays at least ten percent of the amount shown on the notice of discontinuance for regulated charges and enters into an installment payment plan on or before the expiration date of the notice of discontinuance.

(III) The customer pays at least ten percent of any regulated charges amount more than 30 days past due and enters into an installment payment plan on or before the last day covered by a medical certificate. A customer who has entered into and failed to abide by an installment payment plan prior to receiving a medical certificate shall pay all amounts that were due for regulated charges up to the date on which the customer presented a medical certificate which meets the requirements of subparagraph 4407(e)(IV) and then may resume the installment payment plan. (IV) If service has been disconnected, the customer pays at least any collection and reconnection charges and enters into an installment payment plan. This subparagraph shall not apply if service was discontinued because the customer breached a prior payment arrangement.

(d) Installment payment plans shall include the following amounts that are applicable at the time the customer requests a payment arrangement: (I) the unpaid remainder of amounts due for regulated charges shown on the notice of discontinuance;

(II) any amounts due for regulated charges not included in the amount shown on the notice of discontinuance which have since become more than 30 days past due;

(III) all current regulated charges contained in any bill which is past due but is less than 30 days past the due date;

(IV) any new regulated charges contained in any bill which has been issued but is not past due;

(V) any regulated charges which the customer has incurred since the issuance of the most recent monthly bill;

(VI) any other regulated charges and fees as described in paragraph (a) of this rule, except fees relating to service diversion, whether or not such fees have appeared on a regular monthly bill; and (VII) any applicable deposit, consistent with rule 4403. 80 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (e) A customer entering into a payment arrangement as described in paragraph (b) may modify their bill due date if the utility’s billing system allows for such a change.

(f) Within seven calendar days of entering into a payment arrangement with a customer, a utility shall provide the customer with this rule and a statement describing the payment arrangement. The statement describing the payment arrangement shall include the following:

(I) the terms of the payment plan; and (II) a description of the steps which the utility will take if the customer does not abide by payment plan.

(g) Except as provided in subparagraph (c)(I) of this rule, an installment payment plan shall consist, at a minimum, of equal monthly installments for a term selected by the customer but not to exceed 12 months. Notwithstanding the foregoing, a utility may enter into an installment payment plan with a customer for a term up to 24 months if it determines that this is warranted by extraordinary circumstances. In the alternative, the customer may choose a modified budget or level payment plan, or similar tariff payment arrangement in which the total due shall be added to the preceding year's total billing to the customer's premises, modified for any base rate or cost adjustment changes. The resulting amount shall be divided and billed in 11 equal monthly budget billing payments, followed by a settlement billing in the twelfth month, or shall follow other payment-setting practices consistent with the tariff plan available. Utilities may not require a customer to participate in a budget or level payment plan or automated billing as a prerequisite for entering into an installment payment plan. (h) For an installment payment plan entered into pursuant to this rule, the first monthly installment payment, and with the new charges (unless the new charges have been made part of the arrangement amount) shall be due on a date which is not earlier than the next regularly-scheduled due date of the customer who is entering into the installment payment plan. Succeeding installment payments, together with the new charges, shall be due in accordance with the due date established in the installment payment plan. Any payment not made on the due date established in the installment payment plan shall be considered in default. Any new charges that are not paid by the due date shall be considered past due, excluding those circumstances covered in subparagraph (c)(I) of this rule. 81 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (i) This rule shall not be construed to prevent a utility from offering any other installment payment plan terms to avoid discontinuance or terms for restoration of service, provided the terms are at least as favorable to the customer as the terms set out in this rule.

4405. Service, Rate, and Usage Information.

(a) In addition to the requirement found in rule 1206, a utility shall inform its customers of any change proposed or made in any term or condition of its service if that change or proposed change will affect the quality of the service provided.

(b) A utility shall transmit information provided pursuant to this rule through the use of a method (such as, without limitation, bill inserts or periodic direct mail) that will assure receipt by each customer.

(c) Upon request, a utility shall provide the following information to a customer. (I) A clear and concise explanation of the existing rate schedule applicable to the customer, the rate components for that rate schedule, and an explanation of how those components are calculated and applicable to the customer. This shall be provided within ten days of a customer’s request or, in the case of a new customer, within 60 days of the commencement of service.

(II) A clear and concise statement of the customer’s actual consumption or degree-day adjusted consumption of gas for each billing period during the prior year, unless such consumption data are not reasonably ascertainable by the utility.

(III) A clear and concise explanation of the terms and conditions of service applicable to the customer.

(d) A utility shall post and keep current on its website the data required to be submitted pursuant to paragraph 4109(c), including the charts, graphs, or other visualizations demonstrating ten-year historical trends. 4406. Itemized Billing Components.

(III) any amount due on another account now or previously held or guaranteed by the customer, or with respect to which the customer received service, unless the amount has first been transferred either to an account which is for the same class of service or to an account which the customer has agreed will secure the other account. Any amount so transferred shall be considered due on the regular due date of the bill on which it first appears and shall be subject to notice of discontinuance as if it had been billed for the first time;

83 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (IV) any amount due on an account on which the customer is or was neither the customer of record nor a guarantor, or any amount due from a previous occupant of the premises.

(VIII) any unregulated charge; or (IX) any amount which is the subject of a pending dispute or informal complaint under rule 4004.

(c) If the utility discovers any connection or device installed on the customer’s premises, including any energy-consuming device in the proximity of the utility's meter, which would prevent the meter from registering the actual amount of energy used, the utility shall do one of the following. (I) Remove or correct such devices or connections. If the utility takes this action, it shall leave at the premises a written notice which advises the customer of the violation, of the steps taken by the utility to correct it, and of the utility’s ability to bill the customer for any estimated energy consumption not properly registered. This notice shall be left at the time the removal or correction occurs.

(II) Provide the customer with written notice that the device or connection must be removed or corrected within 15 days and that the customer may be billed for any estimated energy consumption not properly registered. If the utility elects to take this action and the device or connection is not removed or corrected within the 15 days permitted, then within seven calendar days from the expiration of the 15 days, the utility shall remove or correct the device or connection pursuant to subparagraph (c)(I) of this rule.

(d) If a utility discovers evidence that any utility-owned equipment has been tampered with or that service has been diverted, the utility shall provide the customer with written notice of the discovery. The written notice shall inform the customer of the steps the utility will take to determine whether non-registration of 84 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission energy consumption has or will occur and shall inform the customer that the customer may be billed for any estimated energy consumption not properly registered. The utility shall mail or hand-deliver the written notice within three calendar days of making the discovery of tampering or service diversion.

(III) Outside the hours of 8:00 a.m. and 4:00 p.m., Monday through Thursday. (IV) Between the hours of 12:00 Noon on the day prior to and 8:00 a.m. on the day following any state or federal holiday or day during which the utility’s local office is closed.

(V) To the greatest extent practicable, a utility shall not disconnect a customer after 11:59 a.m. on a Monday through Thursday.

(VI) Medical emergencies.

(A) A utility shall postpone service discontinuance to a residential customer for 90 days from the date of a medical certificate issued by a Colorado-licensed physician, health care practitioner acting under a physician's authority, or health care practitioner licensed to prescribe and treat patients which evidences that service discontinuance will aggravate an existing medical emergency or create a medical emergency for the customer or a permanent resident of the customer's household. A customer may invoke this subparagraph only once in any twelve consecutive months. 85 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (B) As a condition of obtaining a new installment payment plan on or before the last day covered by a medical certificate, a customer who has already entered into a payment arrangement, but broke the arrangement prior to seeking a medical certificate, may be required to pay all amounts that were due up to the date of the original medical certificate as a condition of obtaining a new payment arrangement.

Such certificate is not contestable by the utility as to the medical judgment, although the utility may use reasonable means to verify the authenticity of such certificate.

(D) A utility may accept notification by telephone from the office of a licensed physician, or health care practitioner licensed to prescribe and treat patients, but a written medical certificate must be sent to the utility within ten days.

(VII) Weather provisions.

(A) A utility shall postpone service discontinuance to a residential customer on any day when the National Weather Service local forecast between 6:00 a.m. and 9:00 a.m. predicts that the temperature will be 32 degrees Fahrenheit (32oF) or lower at any time during the following 24 hours, or during any additional period in which utility personnel will not be available to restore utility service in accordance with rule 4409. Nothing prohibits a utility from postponing service discontinuance when temperatures are warmer than these criteria.

(B) A utility shall postpone service discontinuance to a customer during an emergency or safety event or circumstance impacting the local area.

(f) In addition to its tariffs, a utility shall publish information related to its practices around delinquency, disconnection for nonpayment, and reconnection on its 86 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission website. This information should be written in a manner that promotes customer understanding and must be produced in English and a specific language or languages other than English where the utility’s entire service territory contains a population of at least ten percent who speak a specific language other than English as their primary language as determined by the latest U.S. Census information.

(VI) Levelized budget billing participation. A utility may enroll participants in its levelized budget billing program as a condition of participation in the program, though the utility shall also allow participants the option to opt out of levelized budget billing if they so choose without losing PIPP benefits, which option shall be available to the participants where the utility’s automated billing system is capable. Utilities without automated billing systems capable of permitting opt out of levelized budget billing shall reasonably and prudently modify their systems to facilitate opt out of levelized budget billing. Should a participant fail to meet monthly bill obligations and be placed by a utility in its regular delinquent collection 107 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission cycle, the utility may remove the participant from levelized budget billing in accordance with the utility’s levelized budget billing tariff. (VII) Arrearage credits.

(F) A participant may receive arrearage credits under this section even if that participant does not receive a credit toward current bills. (VIII) Portability of benefits. A participant may continue to participate without reapplication should the participant change service addresses but remain within the service territory of the utility providing the benefit, provided that the utility may make necessary adjustments in the billing amount to reflect the changed circumstances. A participant who changes service addresses and does not remain within the service territory of the utility providing the benefit must reapply to become a participant at the participant’s new service address.

(IX) Payment default provisions. Failure of a participant to make his or her monthly bill payments may result in a utility placing the participant in its 108 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission regular collection cycle.

109 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (C) In order to determine monthly rates applicable to rate classes other than residential, program costs shall be allocated to each retail rate based on each rate class’s share of the test year revenue requirement established in the utility’s last Phase II rate case, or under another reasonable methodology supported by quantifiable information. The monthly rate per this subparagraph to be charged each rate schedule customer shall be clearly stated on a tariff sheet.

(D) Utilities shall separately account for the program year’s program cost recovery and program and administrative costs to determine if the net of program cost recovery and program and administrative cost are in balance during the program year.

(i) No later than December 31 of each year, the utility shall file a report with the Commission in the most recent miscellaneous proceeding for annual low-income filings detailing the net difference between program cost recovery and program costs as of October 31 of each year.

(1) Should the net difference of program cost recovery over program and administrative costs be greater than 50 percent derived in D) above, either positive or negative, and the utility is not currently at the maximum impact for non-participants, the utility shall file with the Commission an advice letter and tariff pages seeking approval for the rates determined in subparagraph 4412(g)(II)(D) in order to bring the projected recovery in balance for the ensuing 12 month period. The revised Residential charge shall not exceed the maximum impact for non-participants in subparagraph 4412(g)(II)(C).

(III) The following costs are eligible for recovery by a utility as program costs: (A) program credits or discounts applied against bills for current usage; (B) program credits applied against pre-existing arrearages; (C) program administrative costs; and (D) Commission-sponsored program evaluation costs required under paragraph 4412(k).

(V) LEAP grants.

(A) The utility may apply energy assistance grants provided to the participant by the LEAP program to the dollar value of credits granted to individual program participants.

(B) If applying LEAP grants first, a utility shall apply any energy assistance benefit granted to the participant by LEAP to that portion of the program participant’s full annual bill that exceeds the participant’s affordable percentage of income payment.

(C) If the dollar value of the energy assistance grant is greater than the dollar value of the difference between the program participant’s full annual bill and the participant’s affordable percentage of income payment, the dollar amount by which the energy assistance grant exceeds the difference will be applied:

(i) first, to any pre-existing arrearages that at the time of the energy assistance grant continues to be outstanding; and (ii) second, to the account of the program participant as a benefit to the participant.

(D) No portion of an energy assistance or LEAP grant provided to a program participant may be applied to the account of a participant other than the participant to whom the energy assistance grant was rendered.

(h) Other programs. In addition to the utility’s low-income program, with Commission approval, a utility may offer other rate relief options to eligible households. (l) Other programs offered by the utility under rule 4412 must be intended to reach income qualified households that do not substantially benefit from the provisions of the low-income program. Such programs may take the form of discount rates, tiered discount rates or other direct bill relief methods where the income qualified household benefitting from the program is granted a reasonable preference in tariffed rates assessed to all residential utility customers.

(II) Cost recovery for other programs combined with the Percentage of Income Payment Plan shall not exceed the maximum impact on residential rates described in subparagraph 4412(g)(II)(C). (i) Energy efficiency and weatherization.

A triennial evaluation of the program provisions under rule 4412 beginning in 2019 shall be undertaken in order to review best practices in similar low-income assistance programs in existence in other regulatory jurisdictions, as well as evaluate operation of each utility’s program for effectiveness in achieving optimum support being provided to income qualified participants. The evaluation shall also recommend modifications if available that improve the delivery of benefits to participants and increase the efficiency and effectiveness of each program as they exist at the point of evaluation. The program evaluation shall include a customer needs assessment provided that adequate funds are available.

(I) Procurement of the third-party vendor that will perform the evaluation will be undertaken by the Colorado Energy Office. The CEO shall seek the involvement of interested stakeholders including, but not limited to, Commission staff, all Commission regulated electric and gas utilities, LEAP, the Office of Consumer Counsel, and Energy Outreach Colorado in the design of the requirements regarding study focus and final reporting. (II) Approval of the third-party vendor shall be the responsibility of the Commission.

UNREGULATED GOODS AND SERVICES 4500. Overview and Purpose.

The purpose of these rules is to establish cost assignment and allocation principles to assist the Commission in setting just and reasonable rates and to ensure that utilities do not use ratepayer funds to subsidize non-regulated activities, in accordance with § 40-3- 114, C.R.S. In order to promote these purposes, these rules also specify information that utilities must provide to the Commission. In providing for review of a utility’s specific cost allocations in other states and jurisdictions, the rules merely contemplate a methodology to allow interested parties to obtain complete information regarding cost allocations. These rules do not expressly or implicitly allow this Commission to order a utility to revise its cost allocations in other jurisdictions or states. 4501. Definitions.

The following special definitions apply only to rules 4501 through 4505. In the event of a conflict between these definitions and a statutory definition, the statutory definition shall apply.

115 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (a) “Activity” means a business activity, product or service whether offered by a Colorado utility, a division of a Colorado utility, or an affiliate of a Colorado utility. (b) “Allocate” or “Allocated” or “Cost Allocation” means to distribute a joint or common cost to or from more than one activity or jurisdiction. (c) “Assigned Costs” or “Cost Assignment” means a cost that is specifically identified with a particular activity or jurisdiction and charged directly to that activity or jurisdiction. At no point in the process of making the cost assignment is an allocation applied.

(d) “Cost Assignment and Allocation Manual” (CAAM) means the indexed document filed by a utility with the Commission that describes and explains the cost assignment and allocation methods the utility uses to segregate and account for revenues, expenses, assets, liabilities, and rate base cost components assigned or allocated to Colorado jurisdictional activities. It includes the cost assignment and allocation methods to segregate and account for costs between and among jurisdictions, between regulated and non-regulated activities, and between and among utility divisions.

(e) “Division” means an activity conducted by a Colorado utility but not through a legal entity separate from the Colorado utility. It includes the electric, gas, or thermal activities of a Colorado utility and any non-regulated activities provided by the Colorado utility.

(f) “Fully Distributed Cost” (FDC) means the process of segregating, assigning, and allocating the revenues, expenses, assets, liabilities and rate base amounts recorded in the utility’s accounting books and records using cost accounting, engineering, and economic concepts, methods and standards. Fully distributed cost includes a return on investment in cases where assets are used. (g) “Fully Distributed Cost Study” is a cost study that reflects the result of the fully distributed revenues, expenses, assets, liabilities and rate base amounts for the Colorado utility to and from the different activities, jurisdictions, divisions, and affiliates using cost accounting, engineering, and economic concepts, methods, and standards.

(h) “Incidental Services” means non-tariff or non-regulated services that have traditionally been offered incidentally to the provisions of tariff services where the revenues for all such services do not exceed:

(I) The greater of $100,000 or one percent of the provider’s total annual Colorado operating revenues for regulated services; or, (II) Such amount established by the Commission considering the nature and frequency of the particular service.

116 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (i) “Jurisdictional” means having regulatory rate authority over a utility. Jurisdiction can be at a state or federal level.

(j) “Regulated activity” means any activity that is offered as a public utility service as defined in Title 40, Articles 1 to 7 C.R.S., and is regulated by the Commission or regulated by another state utility commission or the FERC, or any non-regulated activity which meets the criteria specified in rules 4502(g). (k) “Non-regulated activity” means any activity that is not offered as a public utility service as defined in Title 40, Articles 1 to 7, C.R.S., and is not regulated by this Commission or another state utility commission or the FERC. (l) “Transaction” means the activity that results in the provision of products, services, or assets by one division or an affiliate to another division or an affiliate. 4502. Cost Assignment and Allocation Principles.

In determining fully distributed cost, the utility shall apply the following principles (listed in descending order of required application in paragraphs 4502 (a), (b) and (c) below). (a) Tariff services provided to an activity will be charged to the activity at the tariff rates.

(b) If only one activity or jurisdiction causes a cost to be incurred, that cost shall be directly assigned to that activity or jurisdiction.

(c) Costs that cannot be directly assigned to either regulated or non-regulated activities or jurisdictions will be described as common costs. Common costs shall be grouped into homogeneous cost categories designed to facilitate the proper allocation of costs between regulated and non-regulated activities or jurisdictions. Each cost category shall be fairly and equitably allocated between regulated and non-regulated activities or jurisdictions in accordance with the following principles.

(I) Cost causation. All activities or jurisdictions that cause a cost to be incurred shall be allocated a portion of that cost. Direct assignment of a cost is preferred to the extent that the cost can easily be traced to the specific activity or jurisdiction.

(II) Variability. If the fully distributed cost study indicates a direct correlation exists between a change in the incurrence of a cost and cost causation, that cost shall be allocated based upon that relationship. (III) Traceability. A cost may be allocated using a measure that has a logical or observable correlation to all the activities or jurisdictions that cause the cost to be incurred.

117 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (IV) Benefit. All activities or jurisdictions that benefit from a cost shall be allocated a portion of that cost.

(V) Residual. The residual of costs left after either direct or indirect assignment or allocation shall be allocated based upon an appropriate general allocator to be defined in the utility’s CAAM.

(d) For cost assignment and allocation purposes, the value of all transactions from the Colorado utility to a non-regulated activity shall be determined as follows: (I) if the transaction involves a product or service provided by the utility pursuant to tariff, the value of the transaction shall be at the tariff rate; (II) if the transaction involves a product or service that is not provided pursuant to a tariff, the value of the transaction shall be the higher of the utility’s fully distributed cost or market price. Market price shall be either the price charged by the utility, or if this condition cannot be met, the lowest price charged by another person for a comparable product or service; or (III) if the transaction involves the sale of an asset, the value of the transaction shall be the higher of net-book cost or market price. If the transaction involves the use of an asset, the value of the transaction shall be the higher of fully distributed cost or market price. Market price shall be either the price charged by the utility or if this condition cannot be met, the lowest price charged by another person in the market for the sale or use of a comparable asset, when such prices are publicly available. (e) For cost assignment and allocation purposes, the value of all transactions from a non-regulated activity to the utility shall be determined as follows: 118 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (I) if the transaction involves a product or service that is not provided pursuant to a tariff, the value of the transaction shall be the lower of the fully distributed cost or the market price except if the transaction results from a competitive solicitation process then the value of the transaction shall be the winning bid price. Fully distributed cost in this circumstance, shall be the cost that would be incurred by the utility to provide the service internally. Market price shall be either the price charged by the supplying non-regulated activity or if that condition is not met, the lowest price charged by other persons in the market for a comparable product or service, when such prices are publicly available; or (II) if the transaction involves the sale of an asset, the value of the transaction shall be the lower of net-book cost or market price. If the transaction involves the use of an asset, the value of the transaction shall be at the lower of fully distributed cost or market price. Market price shall be either the price charged by the non-regulated activity or, if this condition cannot be met, the lowest price charged by another person in the market for the sale or use of a comparable asset, where such prices are publicly available.

(f) If it is impracticable for the utility to establish a market price pursuant to paragraphs (d) or (e), the utility shall provide a statement to that effect, including its reasons in its’ fully distributed cost study as well as its proposed method and amount for valuing the transaction. Parties in a Commission proceeding retain the right to advocate alternative market prices pursuant to paragraphs (d) and (e).

(g) A utility may classify non-jurisdictional services as regulated if the services are rate-regulated by another agency (i.e., another state utility commission or the FERC) and where there are agency-accepted principles or methods for the development of rates associated with such services. This rule may apply, for example, to a provider's wholesale sales of electric power and energy. For such services, the utility shall identify the services in its manual, and account for the revenues, expenses, assets, liabilities, and rate base associated with these services as if these services are regulated.

(h) For cost assignment and allocation purposes, the value of all transactions between regulated divisions within a utility shall be determined as follows: (I) if the transaction involves a service provided by the utility pursuant to tariff, the value of the transaction shall be at the tariff rate, or (II) if the transaction involves a service or function that is not provided pursuant to a tariff, the value of the transaction shall be at cost. 119 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (i) If the utility offers a service that is a combination of regulated and non-regulated activities (i.e., a bundled service), the utility shall assign and/or allocate costs to the regulated and non-regulated activities separately.

(j) A utility may classify incidental activities as regulated activities. If an incidental activity is classified as a regulated activity, the utility shall clearly identify the activity as an incidental activity, and account for the revenues, expenses, assets, liabilities and rate base items as if that activity were a regulated activity. (k) To the extent possible, all assigned and allocated costs between regulated and non-regulated activities should have an audit trail which is traceable on the books and records of the applicable regulated utility to the applicable accounts pursuant to the Federal Energy Regulatory Commission Uniform System of Accounts. (l) In a rate proceeding involving the calculation of revenue requirements, a complaint proceeding where cost assignments or allocations are at issue, or a proceeding where CAAM approval is sought, the utility or any party may advocate a cost allocation principle other than that already in use, if the Commission has already approved the principle for that cost. The party requesting the alternative approach shall have the burden of proving the need for an alternative principle and why the particular principle is appropriate for the particular cost.

4503. Cost Assignment and Allocation Manuals.

(a) Each utility shall maintain on file with the Commission an approved indexed cost assignment and allocation manual which describes and explains the calculation methods the utility uses to segregate and account for revenues, expenses, assets, liabilities, and rate base cost components assigned or allocated to Colorado jurisdictional activities. It includes the calculation methods to segregate and account for costs between and among jurisdictions, between regulated and non-regulated activities, and between and among utility divisions. (b) Each utility shall include the following information in its CAAM. (I) A listing of all regulated or non-regulated divisions of the Colorado utility together with an identification of the regulated or non-regulated activities conducted by each.

(II) A listing of all regulated or non-regulated affiliates of the Colorado utility together with an identification of which affiliates allocate or assign costs to and from the Colorado utility.

(III) A listing and description of each regulated and non-regulated activity offered by the Colorado utility. The Colorado utility shall provide a description in sufficient detail to identify the types of costs associated with the activity and shall identify how the activity is offered to the public and identify whether the Colorado utility provides the activity in more than one 120 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission state. If an activity is offered subject to tariff, the Colorado utility may identify the tariff and the tariff section that describes the service offering in lieu of providing a service description.

(IV) A listing of the revenues, expenses, assets, liabilities and rate base items by Uniform System of Accounts account number that the utility proposes to include in its revenue requirement for Colorado jurisdictional activities including those items that are partially allocated to Colorado as well as those items that are exclusively assigned to Colorado.

(V) A detailed description showing how the revenues, expenses, assets, liabilities and rate base items by account and sub-account are assigned and/or allocated to the Colorado utility’s non-regulated activities, along with a description of the methods used to perform the assignment and allocations.

(VI) A description of each transaction between the Colorado utility and a non- regulated activity which occurred since the Colorado utility’s prior CAAM was filed and, for each transaction, a statement as to whether, for this Commission’s jurisdictional cost assignment and allocation purposes, the value of the transactions is at cost or market as applicable. (VII) A description of the basis for how the assignment or allocation is made. (VIII) If the utility believes that specific cost assignments or allocations are under the jurisdiction of another authority, the utility shall so state in its CAAM and give a written description of the prescribed methods. Nothing herein shall be construed to be a delegation of this Commission’s ratemaking authority related to those assignments or allocations. (IX) Any additional information specifically required by Commission order. (c) A utility may treat certain transactions as confidential pursuant to the Commission rules on confidentially.

(d) Following the initial approval of its CAAM, the utility shall file an updated CAAM in each rate case proceeding where revenue requirements are determined or every five years following approval of the CAAM then in effect, whichever is earlier.

(e) The utility may, at its discretion, file an application seeking Commission approval of updates to its CAAM at any time.

(f) Whenever a utility files for approval of an update to its CAAM as a result of paragraph (d) or (e) above, the utility shall also simultaneously file a FDC study reflecting the results of the cost allocation methods in its updated manual. 121 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (g) Each utility shall maintain all records and supporting documentation concerning its CAAMs for so long as such manual is in effect or are subject to a complaint or any active proceeding involving cost allocation before the Commission for as long as such proceeding may be open.

4504. Fully Distributed Cost Study.

(a) The utility shall submit its fully distributed cost study in both electronic and paper format simultaneously with filing its CAAM for all Colorado divisions and activities.

(b) The utility shall prepare a FDC study that identifies all the non-regulated activities provided by each division in Colorado. The FDC study shall show the revenues, expenses assets, liabilities and rate base items assigned and allocated to each non-regulated activity. If the utility has more than one division (e.g., gas, electric, thermal or non-utility) in Colorado, the FDC study shall include a summary of all assigned and allocated costs by division.

(c) In preparation of its FDC study, the utility shall complete an analysis of each non- regulated activity to identify the costs that are associated with and/or should be charged to each non-regulated activity to ensure each non-regulated activity is assigned and allocated the appropriate amount of revenues, expenses, assets, liabilities and rate base items.

(d) If the CAAM is filed in connection with a rate case, the FDC study shall be based on the same test year used in the utility’s rate case filing. The utility’s FDC study shall include revenues, expenses, assets, liabilities and rate base items in order for the Commission to determine if all appropriate revenues, expenses, assets, liabilities and rate base items have been appropriately assigned and allocated, and to determine the utility’s compliance with the principles established in rule 4502. For each assignment and allocation the utility shall: (I) identify the revenues, expenses, assets, liabilities and rate base items by account number, sub-account number and account description; and 122 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (II) for each account in (I) above, identify the assignment and allocation method used to assign and allocate costs in sufficient detail to verify the assignment and allocation method used to assign and allocate costs to Colorado divisions and activities is accurate and consistent with the utility’s CAAM methodology and reference the CAAM section that describes the allocation; and (III) provide the test year dollar itemized amounts of revenues, expenses, assets, liabilities, and rate base assigned and allocated to each Colorado division and non-regulated activity; the itemized amounts assigned and allocated to the Colorado utility for regulated activities; the itemized amounts assigned and allocated to the Colorado utility for Colorado non- regulated activities; and the itemized amounts assigned and allocated to other jurisdictions.

(e) Each utility shall maintain all records and supporting documentation concerning its FDC study for so long as such study is in effect or are subject to a complaint or a proceeding before the Commission.

4505. Disclosure of Non-regulated Goods and Services.

Whenever a Colorado utility engages in the provision or marketing of non-regulated goods or services in Colorado that are not subject to Commission regulation, and the Colorado utility’s name or logo is used in connection with the provision of such non- regulated goods and services in Colorado, there must be conspicuous, clear, and concise disclosure to prospective customers that such non-regulated goods and services are not regulated by the Commission.

(B) The volumes and costs associated with storage injections and withdrawals, including both physical and contract storage, may be excluded from the GPIM and risk sharing calculation. Utilities shall provide a description of storage assets to be either included or excluded from the GPIM.

(C) The volumes and costs associated with associated with financial hedging shall be excluded from the GPIM and risk sharing calculation.

151 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (D) All other actual gas volumes and costs shall be subject to the GPIM with consideration of reasonable adjustments as determined by the Commission.

(III) Upstream supply costs. Description and explanation of upstream costs included in the GPIM risk sharing mechanism, including the methodology for developing an appropriate benchmark for such costs, if appropriate. (IV) Risk sharing amount. Methodology for calculating the risk sharing amount. (A) A formula will calculate a percentage of the difference between the actual gas costs and the benchmark formula for applicable gas volumes, either positive or negative, borne or retained by the utility, subject to applicable limitations.

(B) The utility shall explain:

(i) any proposed deadband around the GPIM benchmark whereby price variation within the deadband is excluded from risk sharing formula;

(ii) any proposed cap or floor on the results of the risk sharing; and (iii) any proposed methodology for applying force majeure or similar provisions to the risk sharing mechanism.

(C) Backcasting analysis, based on a minimum of the most recent three years of historical data, will demonstrate how the proposed GPIM benchmark would have been calculated and how the proposed risk sharing mechanism would have performed over the historical period. This analysis shall assume the utility made no changes to its actions in response to the mechanism and ignore any force majeure or similar events. The utility may, in its discretion, present additional analysis.

152 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (b) An application to establish a GPIM for a utility with more than 500,000 full service customers shall contain the following elements. The utility shall specifically reference and respond to the requirements of subparagraphs (I) through (IV) of this rule and shall provide cross-references and footnoted work-papers in executable format with all cell formulas intact, using spreadsheet software that is compatible with software used by Commission staff.

(I) GPIM benchmark gas rate. The GPIM benchmark gas rate for the completed calendar quarter preceding the GCA filing will be calculated as the average of the GPIM total gas cost for that same quarter in the previous three years divided by the GPIM total gas quantity for the same quarters in the previous three years.

(II) GPIM actual gas rate. The GPIM actual gas rate for the completed calendar quarter preceding the GCA filing will be calculated as the GPIM total gas cost for that quarter divided by the GPIM total gas quantity for that same quarter.

(III) GPIM sharing amount. The GPIM sharing amount will be calculated as four percent of the difference between the GPIM benchmark gas rate and the GPIM actual gas rate, either positive or negative, multiplied by the GPIM total gas quantity for the completed calendar quarter preceding the GCA filing, subject to the following limitations:

(A) the GPIM sharing amount for a quarter shall be zero if the difference between the GPIM benchmark gas rate and the GPIM actual gas rate is less than $0.50 per Mcf or Dth;

(B) the GPIM sharing amount for a quarter shall be the difference between the GPIM benchmark gas rate and the GPIM actual gas rate that is above or below the $0.50 per Mcf or Dth threshold in subparagraph 4607(b)(III)(A); and (C) the utility’s cumulative quarterly GPIM sharing amounts summed across all GCA rate areas or purchasing regions, positive or negative, shall be capped over a rolling twelve-month period at an amount equal to a 30 basis point return on the utility’s rate base as established by the Commission in the utility’s most recent base rate proceeding, set solely on the equity share of the utility’s capital structure.

153 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (IV) The utility may request, and the Commission may grant, a force majeure exception upon good cause shown after such an event has occurred. The force majeure exception may allow the utility to exclude costs from the GPIM that are deemed to be either associated with the force majeure event as defined by the utility’s tariffs on file with the Commission or associated with force majeure events as defined in the utility’s upstream gas supply, storage, and transportation agreements and tariffs. (c) Unless subject to the limitations in subparagraph 4607(a)(IV)(B)(ii) or subparagraph 4607(b)(III)(C), the GPIM sharing amount shall be accounted for in the utility’s deferred gas cost calculation for the quarterly GCA filing. (I) To the extent a GCA calculation is subject to a maximum cap specified in a utility’s GPRMP, any new positive GPIM sharing amount will not be accounted for in the deferred gas cost calculation but instead be subject to a carryforward into subsequent GCA quarterly filings. The carried forward GPIM amount shall be eligible to offset incurred negative GPIM sharing amounts.

(II) To the extent a GCA calculation is subject to a minimum threshold specified in a utility’s GPRMP, any new negative GPIM sharing amount will not be accounted for in the deferred gas cost calculation but instead be accounted for in the deferred gas cost calculation in subsequent quarterly GCA filings in which the GCA calculation is above the minimum threshold.

4608. Gas Purchase and Deferred Balance Reports and Prudence Reviews. (a) GPDBR filing requirements. The utility shall file a GPDBR in accordance with paragraph 4602(e) for the review and approval of the calculation of the deferred GCA balance including the implementation of the utility’s GPIM, as applicable, for the previous four quarters ending June 30. The GPDBR shall be filed under the previous year’s GPP proceeding number (filed approximately 15 months previously). Specific attachments or other information may be filed under seal; however, an explanation of the confidential nature of the attachments or information must be included in the GPDBR filing.

(b) Prudence review process. Based on the initial evaluation of the GPDBR, including the results of the GPIM, the Commission may initiate a prudence review hearing. The Commission shall initiate this hearing by written order within 120 days of the filing of the GDBPR. The prudence review may result in tariff or rate changes that could affect different classifications of customers. (c) Prudence review standard. For purposes of GCA recovery, the standard of review to be used in assessing the utility's action (or lack of action) in a specific gas purchase year is: whether the action (or lack of action) of a utility was reasonable in light of the information known, or which should have been known, 154 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission at the time of the action (or lack of action). The Commission may consider, as appropriate, whether the utility employed carefulness, precaution, attentiveness, and good judgment.

(d) Burden of proof. If the Commission elects to hold a hearing, the utility shall have the burden of proof and the burden of going forward to establish the reasonableness of actual gas commodity and demand costs paid by the utility, actual costs incurred in volatility management, and actual upstream service costs of any nature incurred during the review period.

(e) Utility testimony and attachments. If the Commission sets a hearing, the utility shall file its testimony supporting gas cost recovery for the gas purchase year at issue. The testimony shall be filed in question-and-answer format. The utility shall file its testimony not later than 45 days after the Commission sets the matter for hearing.

(n) As a part of its DSM plan, each utility shall propose a DSM plan with a benefit/cost value of unity (1.0) or greater, using a modified TRC test. (o) For the purposes of calculating and reviewing a modified TRC, the following components shall be included. Forecasted DSM costs and benefits are used to estimate the cost-effectiveness of DSM measures to develop a cost-effective DSM portfolio.

(I) Benefits shall include, but are not limited to, as applicable: the utility’s avoided transmission and distribution capital cost savings associated with reductions or limited growth in design peak demand; energy costs; the participant’s avoided operating and maintenance costs; the valuation of avoided greenhouse gas emissions; and non-energy benefits, as set forth in this rule 4753. The valuation of avoided greenhouse gas emissions shall include the social cost of carbon dioxide and the social cost of methane, consistent with rule 4528.

182 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (II) Costs shall include utility and participant costs. The utility costs shall include the net present value of costs incurred in accordance with the budget set forth in rule 4753. For comparative purposes, in addition to this base case calculation of cost-effectiveness, the utility may also provide a case that does not include the social costs of carbon dioxide and methane. Forecasted DSM costs and benefits are used to estimate the cost effectiveness of DSM measures to develop a cost-effective DSM portfolio.

(III) The initial TRC ratio, which excludes consideration of societal benefits, shall be multiplied by a factor established by the Commission in the utility’s strategic issues proceeding to reflect the value of the societal and non-energy benefits. The result shall be the modified TRC. A utility may propose for approval a different factor for societal impacts, but must submit documentation substantiating the proposed value. (IV) A determination of cost-effectiveness using the modified TRC test by the Commission will ultimately be measured at the DSM portfolio level. (V) For purposes of evaluating a gas DSM program or measure that incorporates innovative technologies with the potential for significant impact, such as energy-saving technologies that go beyond what is achievable using energy efficiency measures alone, the Commission may find the program or measure cost-effective, even if its initial benefit-cost ratio is not greater than 1.0 when calculated using currently available data and assumptions.

(p) Measurement and verification (M & V) plan. The utility shall describe in complete detail how it proposes to monitor and evaluate the implementation of its proposed programs. The utility shall explain how it will accumulate and validate the information needed to measure the plan’s performance against the standards, pursuant to rule 4755. The utility shall propose measurement and verification reporting sufficient to communicate results to the Commission in a detailed, accurate and timely basis.

(q) If a utility files an application to open a DSM strategic issues proceeding pursuant to rule 4761, its subsequent DSM plan application shall include programs and measures to, at a minimum, meet the energy savings targets and policy goals established by the Commission in the strategic issues proceeding. 183 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (r) As a part of its DSM plan, each utility shall describe its consideration of incentives for customers to utilize behind-the-meter thermal renewable resources as defined in § 40-1-102(1.1), C.R.S. If the utility proposes to include such incentives in its DSM plan, the cost of such incentives shall be reflected in the budget proposed under subparagraph (j)(IV) above.

(b) As a part of its M & V program, the utility shall, at a minimum, design a M & V plan to evaluate the effectiveness of the actual DSM measures and programs implemented by the utility. The M & V plan shall address: sampling bias; a data gathering process sufficient to yield statistically significant results; and generally accepted methods of data analysis. The M & V plan shall also include an evaluation of free ridership, spillover, and the net-to-gross ratio. The M & V evaluation shall be implemented at least once per the DSM plan period. Subsequent DSM plan applications shall reflect the results of all completed M & V evaluations.

(c) The M & V evaluation shall, at a minimum, include the following: (I) an assessment of whether the DSM programs have been implemented as set forth in its Commission approved DSM plan;

(II) a measurement of the actual energy savings for each DSM program, in dekatherms per dollar expended and in total dollars, and a comparison to the corresponding utility projections in the approved DSM plan; (III) to the extent feasible, an assessment of the period of time that each DSM measure actually remains in service, and a comparison to the corresponding utility projections in the approved DSM plan; (IV) a summary of the actual benefit/cost ratio for each DSM program within the approved DSM plan;

(V) an assessment of the extent to which education and market transformation efforts are achieving the desired results; and (VI) recommendations for how the utility can improve the market penetration and cost effectiveness of individual DSM programs.

185 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4756. General Provisions Concerning Cost Allocation and Recovery. (a) Amortization periods.

(I) For the base rate method, the utility shall propose the amortization period. The utility shall specify and explain the rationale for the amortization period proposed for each DSM program as a part of its DSM plan application, filed pursuant to rule 4753.

(II) For the expense method, the utility shall recover the annual expenditures projected for that year over a one-year period.

(b) A utility that provides both regulated gas and electric service shall give consideration to the administrative benefits and reduced costs associated with combining gas and electric DSM activities and shall assign costs and benefits appropriately to each plan.

(c) Distribution of DSM program expenses.

(I) The utility shall include in its portfolio-level benefit/cost analysis all indirect costs relating to DSM, including but not limited to DSM customer education, program design, and evaluation costs.

(II) A utility’s existing gas efficiency and conservation customer education tools, such as on-line energy assessment tools or other similar internet based tools, may be included in a utility’s gas DSM plan and costs recovered pursuant to a gas DSM cost adjustment consistent with rule 4758.

(d) Decoupling.

(I) The utility may file for approval of a revenue decoupling mechanism to remove disincentives to the implementation of effective gas DSM programs.

(A) The decoupling rate adjustment mechanism shall ensure that the revenue per customer, as established by the Commission, in setting base rates in a general rate case, is recovered by the utility without regard to the utility’s sales to customers in the applicable rate class or classes after the date the adjusted base rates take effect.

(B) The Commission shall separately calculate, for the rate class or classes to which a decoupling rate adjustment mechanism applies, the regulatory disincentives removed through that decoupling mechanism and collected or refunded by the utility through a tariff mechanism.

186 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (II) The implementation of a revenue decoupling mechanism does not preclude a utility from receiving a G-DSM bonus pursuant to rule 4760. 4757. Funding and Cost Recovery Mechanism.

The purpose of the G-DSMCA is to enable utilities to recover prudently incurred gas DSM program expenses without requiring a change in their base rates for gas sales. All such costs, plus any G-DSM bonus approved by the Commission, shall be recovered through the G-DSMCA that is set on an annual basis, and collected from July 1 through June 30. The G-DSMCA allows for prospective recovery of prudently incurred costs of DSM programs within the DSM program expenditure target approved by the Commission in order to provide for funding of the utility’s DSM programs, as well as recovery of deferred G-DSMCA costs, without having to file a rate case. (a) A utility may spend a disproportionate share of total expenditures on one or more classes of customers, provided, however, that cost recovery for programs directed at residential customers are to be collected from residential customers only and that cost recovery for programs directed at nonresidential customers are to be collected from nonresidential customers only, except as provided for in paragraph 4757(f).

(b) The utility may recover its DSM program expenditures either through expensing or by adding DSM program expenditures to base rates as a part of, or outside of, a rate case, with an amortization period as set forth in rule 4756. (c) There shall be no financial penalty assessed on a utility for failing to reach its approved DSM program expenditure target, nor shall there be a bonus simply for meeting its DSM program expenditure target. All prudently incurred expenditures for the utility’s portfolio of DSM programs are recoverable. However, the portion of costs yielding a modified TRC test value below 1.0 loses its presumption of prudence and is subject to review.

(d) Amounts not spent under the DSM program expenditure target shall not roll-over to the next DSM period.

(e) A utility has the discretion and the responsibility of managing the portfolio of DSM programs to meet the benefit to cost ratio and the energy and savings targets. In implementing DSM programs, a utility shall use reasonable efforts to maximize energy savings consistent with the approved DSM plan.

187 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (f) A utility may continue DSM programs that were in existence on or before May 22, 2007, the effective date of § 40-3.2-103, C.R.S., concerning measures to promote energy efficiency, and shall not be required to obtain approval from the Commission for recovery of costs associated with such programs. Any new expenditure for such programs must be included in the annual DSM plan filing and G-DSMCA application. Existing low-income DSM programs that recover costs from all customer classes shall continue such recovery. (g) A utility shall file a request to adjust its G-DSMCA factor either through an application or an advice letter and tariffs, pursuant to the relevant provisions of title 40, articles 1 through 7 of the Colorado Public Utilities Law and of the Commission rules. The G-DSMCA shall be filed pursuant to the schedule provided in rule 4752.

(h) The G-DSMCA filing shall include information and attachments as required in rule 4758. If the M & V evaluation required by rule 4755 yields benefit/costs test results that impact the allowable recovery of costs or currently approved bonus, then the utility shall include such adjustments in the G-DSMCA filing and tariffs. (i) If the projected DSM program costs have changed from those used to calculate the currently effective G-DSMCA cost or if a utility’s deferred G-DSMCA cost balance increases or decreases sufficiently, the utility may file an application to revise its currently effective G-DSMCA factor to reflect such changes, provided that the resulting change to the G-DSMCA factor equates to a base rate change of at least one cent ($0.01) per Mcf or Dth. A utility has the burden of proof to justify any interim G-DSMCA filings and the Commission has the discretion to consolidate the interim G-DSMCA filing with the next regularly scheduled annual G-DSMCA filing.

(j) Applicability of the G-DSMCA factor. The G-DSMCA factor shall be separately calculated and applied to the utility sales gas base rate schedules of residential and non-residential customers.

(k) Return on DSM program expenditures to be amortized. For utilities that choose to amortize the DSM program expenditure, the balance of a utility’s investments in cost-effective DSM programs shall earn a return equal to the utility’s current after-tax weighted average cost of capital.

(l) Interest on under- or over-recovery. The amount of net interest accrued on the average monthly balance in sub-accounts of Account No. 186 (whether positive or negative), is determined by multiplying the monthly balance by an interest rate equal to the Commission-authorized after-tax weighted average cost of capital. (m) Calculation of the G-DSMCA factor. The G-DSMCA factor shall be calculated separately for residential and non-residential customers to at least the accuracy of two significant places.

188 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4758. Contents of Gas DSM Cost Adjustment Filing.

(a) General provisions.

(I) A filing for a gas DSM cost adjustment (G-DSMCA) shall contain justifying information sufficient in detail to permit the Commission to determine the accuracy of the supporting calculation.

(II) The G-DSMCA filing shall include a complete set of work papers and all other documents relied on in preparing the adjustment.

(III) The provisions of this rule do not supersede other Commission rules that contain additional applicable filing requirements.

(b) Specific provisions. The filing shall contain detailed schedules and supporting documents that establish, at a minimum, the following:

(I) the detailed calculation of the G-DSMCA for each customer class based on the following general formula:

(A) current G-DSMCA factor = (current G-DSMCA cost + deferred G- DSMCA cost) / (forecasted sales customer x monthly service charge + forecasted sales gas quantity x base rate); and (B) the G-DSMCA factor will also include the current G-DSM bonus plus any adjustment necessary to previously approved G-DSM bonuses;

(II) a detailed schedule showing the computation of interest, as applicable, to deferred amounts;

(III) the absolute and percentage impact of the proposed rate on the base rates and on the total monthly bills of typical customers in each customer class;

(IV) a schedule detailing the allocation of costs to each customer class; (V) proposed customer notice detailing rate impact and effective date; (VI) proposed tariff implementing the proposed G-DSMCA; and 189 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (VII) if any gas DSM costs are proposed to be recovered by rate base treatment, with a return on the unamortized balance, a statement of current net operating earnings, a detailed calculation of the related revenue requirement and an attachment detailing any differences in the proposed rate base treatment compared to the regulatory practices employed by the Commission in its last general rate case for the applicant. 4759. Bill Itemization.

Consistent with rule 4406, a utility shall provide itemized gas cost information with gas DSM costs to all customers commencing with the first complete billing cycle in which the new rates are in effect.

4760. Gas DSM Bonus (G-DSM Bonus).

(a) The Commission shall determine a financial bonus structure for gas DSM. The bonus amount shall be a percentage net economic benefits resulting from a DSM plan over the period under review, with the specific structure and calculation mechanism of the bonus determined by the Commission in the utility’s strategic issues proceeding.

(b) The Commission shall review each G-DSM bonus calculation and shall determine the level of bonus, if any, for which the utility is eligible consistent with the bonus framework established in the utility’s most recent strategic issues proceeding. The collection on any G-DSM bonus awarded will be apportioned between residential and nonresidential customers based on the proportion of residential and nonresidential net economic benefits used to calculate the G- DSM bonus.

(c) The G-DSM bonus, as modified and approved by the Commission, shall not count against a gas utility’s authorized rate of return or be considered as net operating earnings in rate proceedings.

(d) In the G-DSM bonus filing, the utility shall submit to the Commission the following, at a minimum:

(I) documented expenditures on DSM programs for the current G-DSMCA period;

(II) energy savings and peak demand reductions for the calendar year for which the bonus is to be awarded estimated following and the techniques approved in the DSM plan. The utility shall explain whether the actual gas savings are validated through the measurement and verification process as approved in the utility’s DSM plan;

190 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (III) estimated cost-effectiveness of program expenditures for the current G- DSMCA period in terms of the amount of gas saved per unit of program expenditures;

(IV) actual gas savings and the techniques used to calculate these gas savings for the prior G-DSMCA period. The utility shall explain whether the actual gas savings are validated through the measurement and verification process, pursuant to rule 4755;

(V) actual cost-effectiveness of program expenditures for the prior G-DSMCA period in terms of the amount of gas saved per unit of program expenditures. The utility shall explain whether the actual cost effectiveness of program expenditures is validated through the measurement and verification process, pursuant to rule 4755; (VI) proposed tariffs containing rates to collect the bonus over 12 months; and (VII) any additional information required by the Commission in the utility’s most recent strategic issues proceeding.

(e) For the purposes of calculating the bonus, the costs and benefits associated with an income-qualified DSM program may be excluded from the calculation of the net economic benefits for the entire DSM portfolio if the modified TRC value for the income-qualified program is below 1.0. If the modified TRC value for the income-qualified program is above 1.0, the Commission may exclude the net economic benefits attributable to income-qualified programs from the bonus if the utility has met its targets for income-qualified programs. (f) For the purpose of calculating the bonus, the modified TRC shall be calculated in accordance with paragraph 4753(o), unless otherwise specified in paragraph 4760(e).

(g) The maximum bonus is 20 percent of net economic benefits or 25 percent of expenditures, whichever is less, or any other incentive cap set by the Commission in the utility’s strategic issues proceeding. (h) Any awarded bonus shall be authorized as a supplement to a utility and not count against its authorized rate of return or be considered in rate proceedings. The awarded bonus shall be recovered through the G-DSMCA over a 12-month period after approval of the bonus.

(i) Any combined electric and gas utility seeking a G-DSM bonus for new residential or commercial construction shall provide a narrative discussion that explains why that gas DSM program does not incent additional gas usage as compared to a beneficial electrification alternative.

(j) Accounting for G-DSM bonus shall follow what has been prescribed for G- DSMCA costs, specifically in regard to interest on over- and under- recovery. A 191 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission separate sub-account in Account No. 186 shall be created for any deferred G- DSM bonus amount.

(k) If the Commission finds that the actual performance varies from performance values used to calculate the G-DSM bonus in rule 4754, then an adjustment shall be made to the amount of G-DSM bonus award. Any true-up in G-DSM bonus will be implemented on a prospective basis.

4761. Filing of DSM Strategic Issues Applications.

(a) Commencing in 2022, and no less frequently than every four years thereafter unless otherwise directed by the Commission, each utility shall file an application to open a DSM strategic issues proceeding. Strategic issues proceedings shall result in the development of energy savings and peak demand reduction goals to be achieved by the utility, taking into account its potential for cost-effective DSM as well as the State of Colorado’s greenhouse gas reduction goals in accordance with § 25-7-102(2)(g), C.R.S.

(b) In its application to open a DSM strategic issues proceeding, the utility shall provide:

(I) an estimated budget, corresponding energy savings and peak capacity reduction goals for all DSM programs;

(II) funding and cost-recovery mechanisms;

(III) a proposed methodology for estimating peak demand savings and the resulting cost savings;

(IV) an analysis of the comparative economics of DSM measures and programs, distinguished by the following:

(A) new construction;

(B) existing homes and businesses; and (C) all building types;

(V) an analysis of the comparative economics of DSM measures and programs, particularly targeted at the weatherization of existing homes, and beneficial electrification;

(VI) a proposed financial bonus structure for DSM programs implemented by the utility, including any methodologies or formulas used to determine the bonus under that structure;

(VII) for only combined electric and gas utilities, and only for new construction, a narrative analysis of the impact of the proposed gas DSM measures on 192 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission the comparative economics of beneficial electrification versus the gas alternative; and (VIII) a cost effectiveness methodology and assumptions that will be in effect during the time period of the goals and budgets set in the strategic issues proceeding.

(c) If the filing of an application to open a strategic issues proceeding overlaps with the filing of a DSM plan application pursuant to paragraph 4752(e), a utility with 250,000 or more full-service customers may request Commission approval for an extension of its currently effective DSM plan until the strategic issues proceeding is concluded. The utility will then file a new DSM plan application with proposed programs and measures to meet the energy savings goals and policy goals established by the Commission in the strategic issues proceeding. (d) Notwithstanding the requirements in paragraph 4761(a), for gas utilities with fewer than 250,000 full-service customers, the energy savings targets, a budget for gas DSM program expenditures, funding and cost-recovery mechanisms, and a financial bonus structure may be established in the same proceeding in which the utility’s DSM plan is submitted for approval.

(e) In its decision addressing the utility’s application, the Commission will establish: (I) savings goals for the utility to be addressed by DSM plan filings in accordance with rule 4753;

(II) an estimated budget for DSM program expenditures commensurate with the savings goals;

(III) a modifying factor to include in the TRC test to account for non-energy societal benefits (excluding the benefits incorporated in the social cost of carbon, the social cost of methane, and other provisions in these rules; and (IV) a structure for any gas DSM bonus awarded to the utility in accordance with rule 4760. The bonus structure shall reward the utility’s investment in cost-effective DSM programs and shall result in an annual bonus amount that reflects the extent to which the utility has achieved the targets established in subparagraphs (I) and (II) above.

193 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4762. – 4799. [Reserved].

MASTER METER OPERATORS 4800. Scope and Applicability.

These rules are applicable to any person who purchases gas service from a serving utility for the purpose of delivery of that service to end-users whose aggregate usage is measured by a master meter or other composite measurement device. 4801. Definitions.

The following definitions apply to rules 4800 through 4805, unless a specific statute or rule provides otherwise. In the event of a conflict between these definitions and a statutory definition, the statutory definition shall apply. (a) “Check-meter” means a meter or other composite measurement device used by a master meter operator to determine gas consumption by end-users served by the master meter operator.

(b) “Master meter” means a meter or other composite measurement device which a serving utility uses to bill a master meter operator.

(c) “Master meter operator” (MMO) means a person who purchases gas service from a serving utility for the purpose of delivering that service to end-users whose aggregate usage is measured by a master meter.

(d) “Refund” means a refund, rebate, rate reduction, or similar adjustment. (e) “Serving utility” means the utility from which the master meter operator receives the gas service which the master meter operator then delivers to end-users. 4802. Exemption from Rate Regulation.

(a) Pursuant to § 40-1-103.5, C.R.S., and by this rule, the Commission exempts from rate regulation under Articles 1 to 7 of Title 40, C.R.S., a master meter operator which is in compliance with rules 4803 and 4804.

(b) A master meter operator which is not in compliance with rules 4803 and 4804 is subject to rate regulation under Articles 1 to 7 of Title 40, C.R.S., and shall comply with the applicable rules.

4803. Exemption Requirements.

(a) In order to retain its exemption from rate regulation, a MMO shall do the following.

194 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission (I) As part of its billing for utility service, the MMO shall charge its end-users only the actual cost billed to the MMO by the serving utility. The MMO shall not charge end-users for any other costs (such as, without limitation, the costs of construction, maintenance, financing, administration, metering, or billing for the equipment and facilities owned by the MMO) in addition to the actual costs billed to the MMO by the serving utility. (II) If the MMO bills its end-users separately for service, the sum of such billings shall not exceed the amount billed to the MMO by the serving utility.

(III) If the MMO bills its end-users separately for service, the MMO shall pass on to its end-users all refunds the MMO receives from the serving utility or otherwise.

(IV) The MMO shall establish procedures for giving notice of a refund to those who are not current end-users but who were end-users during the period for which the refund is paid.

(V) A master meter operator shall retain, for a period of not less than three years, all records of original utility billings made to the master meter operator and all records of billings and refunds made by the master meter operator to its end-users, including certification of mailing, when applicable.

(b) In order to retain its exemption from rate regulation, a MMO shall not resell the services provided by a serving utility to the MMO for profit. Resale of services provided by a serving utility to a MMO for profit is a basis for revocation of an exemption from rate regulation.

(c) A MMO may check-meter tenants, lessees, or other persons to whom the gas ultimately is distributed but may do so only if the following conditions are met: (I) the check-meter is used solely for the purpose of determining a basis for the MMO to allocate the costs of the serving utility; and (II) the MMO does not receive more than the actual amount billed to the MMO by the serving utility from the MMO’s customers.

195 CODE OF COLORADO REGULATIONS 4 CCR 723-4 Public Utilities Commission 4804. Refunds.

(a) When a serving utility notifies a MMO of a refund or when a refund is otherwise made related to the services provided by the serving utility to the MMO, a MMO shall refund an allocated share of the refunds to its customers within 90 days after receipt of the notice or refund from the serving utility. The notification shall be made either by first-class mail with a certificate of mailing or by inclusion in any monthly or more frequent regular written communication. The MMO shall retain the certification of mailing pursuant to subparagraph 4803(a)(V). The MMO shall also notify former customers who were end-users during the period for which the refund is made that refunds are available, to the extent such former customers can be located.

(b) A MMO may retain any portion of a refund which is related to service taken by the MMO at its own facilities after refunds are made to its current and former customers.

(c) If the aggregate amount of a refund which remains unclaimed after 90 days exceeds $100, the MMO shall contribute that unclaimed amount to the energy assistance organization in accordance with rules 4410(d), (f), and (g). If the aggregate amount which remains unclaimed after 90 days does not exceed $100, the MMO may retain the aggregate amount.

4805. Complaints, Penalties, and Revocation of Exemption. (a) Pursuant to rules 1301 and 1302, a person (including without limitation anyone taking service from a master meter operator) may make an informal complaint to the Commission or may file a formal complaint with the Commission with the respect to an alleged violation of rules 4803 and 4804. (b) As a result of a complaint or on its own motion, the Commission will investigate complaints concerning MMOs. If the Commission determines after investigation that an MMO has violated any of the requirements of rules 4803 and 4804, the MMO may have its exempt status revoked or may be subject to penalties as set forth in § 40-7-107, C.R.S., or both.
