Adopted by Assembly Bill 117 (AB 117) in 2002, Community Choice Aggregation (CCA):

AB 117 provided that “all electrical corporations must cooperate fully with any community choice aggregators that investigate, pursue, or implement community choice aggregator programs.” The investor-owned utility still maintains the responsibility of providing transmission and distribution services, and continues to provide all metering, billing, collection, and customer service to retail customers that participate in a CCA. AB 117 also provided guidance on how communities may create a CCA program. AB 117 requires that the city or county pass an ordinance to implement a CCA program within its jurisdiction. Two or more cities or counties may participate in a CCA program as a group through a joint powers agency. Once a community has established a CCA program potential customers with in the service area are automatically enrolled in the CCA unless they opt out so long as customers have been noticed in writing of their right to opt out of CCA service. Customers who opt out of CCA service continue to be served as bundled customers of the IOU electrical corporation.

CCAsare responsible to meet regulatory compliance requirements established in Resource AdequacyIntegrated Resource Planning (IRP), and Renewable Portfolio Standards (RPS). CCAs are responsible for tracking and compliance with CPUC regulations.

CCA En Banc Background Information

A number of new Community Choice Aggregators (CCAs) have formed in California in recent years, and there is a potential for significant additional CCA growth. On February 1, 2017, the CPUC held an En Banc hearing considering how various programs and regulatory activities would be affected as CCA growth continued. This paper was developed by Energy Division staff to provide background information on CCAs in support of the CCA En Banc hearing.



CCA Registration Process

Resolution E-4907establishesthe process for city or jurisdiction toregister and implement a CCAwith CPUC. The ruling outlines regulatory requirements related to submission of an Implementation Plan, Resource Adequacy requirements, bond payments and customer notifications



The CCA’s customers are responsible for the PCIA.  The PCIA ensures that customers that stay with the IOU do not bear costs for energy that has been procured for customers that have left for a CCA.


A Provider of Last Resort (POLR) is required to continue electric energy service to customers in the event of a CCA failing to do so.  Currently the IOU has the responsibilities to be the POLR.  In 2019 SB 520 was enacted for the CPUCto develop a more comprehensive POLR framework.  The CPUC established R.21-03-011 to enact SB 520.


IOU Code of Conduct (D.12-12-036): In SB 790, the legislature directed the Commission to develop rules and procedures that “facilitate the development of community choice aggregation programs, … foster fair competition, and … protect against cross-subsidization paid by ratepayers.”


Code of Conduct Audit: The State Controller’s Office (SCO) conducted a performance audit of Pacific Gas and Electric Company’s (PG&E) compliance with the Community Choice Aggregation Code of Conduct Rules (CCA CCR) program adopted in Decision (D) 12-12-036 by the five-member Commission (Commission), the members of which sit on the California Public Utilities Commission (CPUC), pursuant to Assembly Bill 117 and Senate Bill 790.
