Learn More about Community Choice Aggregation


If you are a city, county, or Joint Powers Authority (JPA) planning to participate in CCA Service, you should first develop an understanding of the California electric market restructuring process and protocols. We recommend that entities interested in providing CCA Service review the California Public Utilities Commission’s (CPUC) website for further information on CCA, including:

Register and File Implementation Plan with California Public Utilities Commission (CPUC)

Are you an eligible entity planning to participate in the CCA service? The process outlined below is the CPUC-approved process to submit a notification of intent to become a CCA. The steps are further described on the CPUC website.

  • Develop an Implementation Plan
  • Prepare a Statement of Intent
  • Register and file an Implementation Plan with the CPUC
  • Provide financial security to SCE

SCE’s Role in Community Choice Aggregation

SCE’s Role in Generation

SCE has no role in generation for CCA customers. The generation is solely provided by the CCA.


SCE’s Role in Transmission

California’s Investor Owned Utilities (IOUs), including SCE, continue to own and maintain their transmission facilities (the highest voltage lines), but have turned operational control of these facilities over to the California Independent System Operator (CAISO) per AB1890, which restructured the electric utility industry in California. The CAISO operates the overall transmission system to ensure that all generation suppliers have equal opportunity to send their electricity through the transmission system to consumers, and to maintain the balance between the supply and demand for electricity. The CAISO also assumes responsibility for the safety and reliability of the transmission system.

SCE’s Role in Distribution

SCE continues to own and operate the regulated distribution lines in its franchise territory and is responsible for the reliable and safe delivery of electricity to end-use customers.

CCA’s Role in Community Choice Aggregation

Under CCA Service, the CCA is responsible for procuring the generation portion of its customers’ electricity service (including ancillary services). The CCA is responsible for ensuring that the power needs of CCA Service customers are scheduled and settled with the CAISO. Additionally, CCAs are responsible for customer communications and customer inquiries regarding, and the management and oversight of, their own CCA Service programs.
