Community Choice Aggregation

Community Choice Aggregation, or CCA, is a program available within the service areas of investor-owned utilities, such as PG&E, which allows cities and counties to purchase and/or generate electricity for their residents and businesses. Under CCA, PG&E continues to deliver the electricity through its transmission and distribution system and provide meter reading, billing, maintenance, and outage response services.

To learn more about CCA, see frequently asked questions or call PG&E at 1-866-743-0335.

Customers may only opt out of an established CCA program by contacting their CCA.
