Community Choice Aggregation (CCA) was enacted by Assembly Bill 117 (AB 117) in 2002. Under AB 117, "all electrical corporations must cooperate fully with community choice aggregators investigating, pursuing, or implementing community choice aggregator programs."

The IOU continues to provide transmission and distribution, metering, billing, collection, and customer service to retail customers participating in CCAs. 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. Potential customers within a community's service area are automatically enrolled in a CCA program unless they opt out, provided that they are notified in writing of their right to opt out. In the event that a customer opts out of CCA service, the IOU will continue to serve them as bundled customers.

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

CCA EnBanc Background Information

Community Choice Aggregation EnBanc Background Paper 

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 EnBanc hearing considering how various programs and regulatory activities would be affected as CCA growth continued. The purpose of this paper is to provide background information on CCAs in support of the EnBanc hearing on CCAs.

CCA Registration Process

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

Power Charge Indifference Adjustment (PCIA)

The CCA's customers are responsible for the PCIA. PCIA ensures that customers staying with the IOU do not bear the cost of energy procured for customers leaving the IOU.

Provider of Last Resort

Providers of Last Resort (POLRs) are required to continue electric energy service when a CCA fails to provide it to customers. SB 520 passed in 2019 to require the CPUC to develop a comprehensive POLR framework. To enact SB 520, the CPUC established R.21-03-011. The IOU is currently responsible for being POLR.

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, help foster fair competition, and help protect against cross-subsidization paid by ratepayers.

Code of Conduct Audit: The State Controller's Office conducted a performance audit of Pacific Gas and Electric Company (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.
