(41) “Publicly available,” when referring to a charger, means a charger and associated parking space or spaces designated, such as by a property owner or lessee, to be available to, and accessible by, the public for any period of time. A charger designated, such as by a property owner or a lessee, to be available only to customers or visitors of the business is a publicly available charger for purposes of this chapter. Chargers and associated parking spaces located in parking garages or gated facilities are considered publicly available for purposes of this chapter if any member of the public can obtain vehicular access to the facility for free or through payment of a fee. If a charger and associated parking space is made available to the public for only limited time periods, that charger and associated parking space is considered a publicly available charger.
- (A) A workplace charging station if it is clearly marked and operated as available exclusively to the organization's employees or independent contractors.
- (B) A charger and associated parking spaces reserved exclusively to residents, tenants, visitors, or employees of: a private residence or common interest development; or a residential building adjacent to a private residence.
- (C) A charger provided by a manufacturer of electric vehicles for the exclusive use by vehicles it manufactures.
- (D) A research charger, as defined in this section.
A publicly available charger does not include any of the following:
- (42) “Publicly or ratepayer funded charger” means a charger installed on or after January 1, 2024, except at a residential real property containing four or fewer dwelling units, for which an incentive was received from a state agency or a charge on ratepayers, or both, to install or operate the charger or its associated charging station. An incentive from a state agency includes, without limitation, any incentive funded in whole or in part from the Greenhouse Gas Reduction Fund as defined in section 16428.8 of the Government Code. A charge on ratepayers includes, without limitation, charges on the customer of an investor-owned utilities, local publicly owned electric utility as defined in section 224.3 of the Public Utilities Code, or community choice aggregator as defined in section 331.1 of the Public Utilities Code. For purposes of these regulations, an incentive from a state agency includes, without limitation, pass-through funds for a federal grant administered by a state agency, for which the state agency is reimbursed, including but not limited to, the CEC's National Electric Vehicle Infrastructure Formula Program. A charger remains a “publicly or ratepayer funded charger” for six years from the date the charger is installed, and thereafter it is no longer a “publicly or ratepayer funded charger.” If a “publicly or ratepayer funded charger” is replaced, its replacement charger is also a “publicly or ratepayer funded charger” for at least the remainder of the six years from the date the replaced charger was previously installed. If an incentive is received from a state agency or a charge on ratepayers, or both, to replace a charger, then the replacement charger is a “publicly or ratepayer funded charger” for six years from the date the replacement charger replaced the prior charger.
- (43) “Recordkeeping and reporting agent” means the entity responsible to ensure timely compliance with the recordkeeping and reporting requirements of this Article. The identity of the recordkeeping and reporting agent is determined according to Section 3122.
- (44) “Replaced” means that the charger has been substantially modified or substituted with another unit, as indicated by a change in the serial number, ID, or the model name.

- (47) “Single-family residence” means a detached or semi-detached (semi-attached, side-by-side) residence, duplex, triplex, quadruplex, row house such that each row house shares at least one wall with another of the row houses even if not in a row, townhouse, or manufactured home, including mobilehome, unless the residence is part of a condominium as defined in Civil Code section 4125 or is located in a mobilehome park.
- (48) “Site host” means the electric utility customer of record for electric service to the charger and can also be the charging network provider or the charging station operator of the charger.
- (49) “Software” means a set of instructions, data, or programs used to operate computers and execute specific tasks.
- (50) “Temporary charger” means a charger that is designed to be portable and available for use intermittently, is not attached at a location, and is not available for use at a single lot or parcel, or an adjacent lot or parcel, for more than 30 days in a calendar year. For the purposes of this definition, a charger that is made available for use for any portion of a day, is considered available for use for that full day.
- (51) “Uninstalled” means the charging station operator took affirmative steps to make the charger unavailable for a charging session with intent to make it permanently unavailable, such that the number of chargers at the charging station is reduced by the number of uninstalled chargers for at least one year. Affirmative steps required to qualify as “uninstalled” include at least labeling the charger in a way that notifies drivers that it is not operational without the need to interact with the charger and updating the data field shared pursuant to section 3130(a)(6) to be consistent with uninstalled status. Mere failure to repair a malfunctioning charger does not make it “uninstalled.”
- (52) “Uptime” means the time that a charger is installed during a reporting period excluding downtime pursuant to section 3124(c) and (d).
