Renewables Portfolio Standard (RPS) Certification

Under California's Renewables Portfolio Standard (RPS) statutes, all sellers of electricity in California, including publicly owned utilities (POUs), investor-owned utilities (IOUs), electricity service providers (ESPs), and community choice aggregators (CCAs), are required to procure a portion of their electricity retail sales from eligible renewable resources to meet the following goals:

Procurement from a renewable facility cannot be counted towards a utility's RPS obligation unless that facility has been certified as RPS-eligible by the California Energy Commission. Facility owners interested in entering into an RPS contract with a utility should certify the facility with the Energy Commission.

Renewable facilities that are under development and not yet commercially operational using a renewable fuel may seek "precertification," with the understanding that the Energy Commission will verify the information submitted in the pre-certification application once the facility has been completed and evaluate this information under the Renewables Portfolio Standard RPS Eligibility Guidebook that is in place when the facility applies for RPS certification.

All certified and precertified facilities are subject to audit as described in the Renewables Portfolio Standard RPS Eligibility Guidebook. The Western Renewable Energy Generation Information System (WREGIS) has been developed to satisfy current RPS tracking requirements. All RPS-certified facilities must register with and be approved in WREGIS. (See the Renewables Portfolio Standard RPS Eligibility Guidebook for more information).

The list will also be modified as needed to reflect any changes in certification information or status of facilities. The list is originally sorted by RPS ID number, but the spreadsheet version can be downloaded and sorted as desired.
