Sec. 4. (a) Each investor-owned electric utility shall provide each of the following three (3) procedures for applications for interconnection of customer-generator facilities and use:

1. (1) The Level 1 review procedure described in section 6 of this rule for applications to connect inverter-based customer-generator facilities that:

   1. (A) have a nameplate capacity of ten (10) kilowatts or less; and
   2. (B) meet the certification requirements of section 5 of this rule.

2. (2) The Level 2 review procedure described in section 7 of this rule for applications to connect customer-generator facilities:

   1. (A) with a nameplate capacity of two (2) megawatts or less; and
   2. (B) that meet the certification requirements of section 5 of this rule.
3. (3) The Level 3 review procedure described in section 8 of this rule for applications to connect customer-generator facilities to its distribution system that do not qualify for either Level 1 or Level 2 interconnection review procedures.

(b) Each utility shall designate a contact person or office from which an eligible customer can obtain basic application forms and information through an informal process.

(c) Each utility shall use commission-approved interconnection application and interconnection agreement forms.

(d) The utility may require the applicant to include a disconnect switch as a supplement to the equipment package.

(e) Application and interconnection review fees shall be set as follows:

1. (1) A utility shall not charge an application or other fee to an applicant that requests Level 1 interconnection review. However, if an application for Level 1 interconnection review is denied because the:

   1. (A) application does not meet the requirements for Level 1 interconnection review; and
   2. (B) applicant resubmits the application under another review procedure;
2. the utility may impose a fee for the resubmitted application, consistent with this section.

3. (2) For a Level 2 interconnection review, the utility may charge fees up to fifty dollars ($50) plus one dollar ($1) per kilowatt of the customer-generator facility's nameplate capacity, plus the cost of any minor modifications to the electric distribution system or additional review, if required under section 7(q)(3) of this rule. Costs for minor modifications or additional review shall be:

   1. (A) based on utility estimates; and
   2. (B) subject to review by the commission or its designee.
4. Costs for engineering work done as part of any additional review shall not exceed one hundred dollars ($100) per hour.
5. (3) For a Level 3 interconnection review, the utility may charge fees up to one hundred dollars ($100) plus two dollars ($2) per kilowatt of the customer-generator facility's nameplate capacity, as well as charges for actual time spent on any impact or facilities studies required under section 8 of this rule. Costs for engineering work done as part of any impact or facilities study shall not exceed one hundred dollars ($100) per hour. If the utility must install facilities in order to accommodate the interconnection of the customer-generator facility, the cost of such facilities shall be the responsibility of the applicant.

(f) The interconnection and operation of any customer-generator facility is secondary to and shall not interfere with the ability of the utility to meet its primary responsibility of furnishing reasonably adequate service to all customers.

(g) All the customer-generator facility electrical installations shall conform to the following:

1. (1) The requirements of local ordinances and inspection authorities.
2. (2) The applicable requirements of this rule.
