Community Choice Aggregation (CCA): What is it?


You may not have heard of Community Choice Aggregation (CCA), but local not-for-profit CCA programs are a positive force in communities across California. Through CCA, communities can purchase electricity on behalf of residents and businesses, in place of investor-owned utilities such as Pacific Gas & Electric, San Diego Gas & Electric, and Southern California Edison.  Over the last decade, local governments in more than 200 towns, cities, and counties throughout the state have chosen to participate in CCA to meet climate action goals, provide residents and businesses with more energy options, ensure local transparency and accountability, and drive economic development. There are currently 25 operational CCA programs in California serving more than 15 million customers, and with many more in progress, those numbers are set to grow.

How Community Choice Works


Through Community Choice Aggregation (CCA), communities can join together to pool (or aggregate) their electricity load in order to purchase clean energy and develop local projects and programs on behalf of their residents and businesses. Aggregators work in partnership with the region’s existing Investor-Owned Utility (IOU), which continues to deliver power and maintain the grid.

Why CCA?


  • Consumer choice, local control, and accountability
  • Policy tool to help communities reach their climate and economic goals
  • Transition to a cleaner, more efficient energy supply
  • Revenues reinvested in the community, not distributed to shareholders
  • Development of new renewable energy projects
  • Tool for communities to establish local energy resources and programs such as solar+storage for resilience, low-income solar, EV vehicle and infrastructure incentives, feed-in-tariff, net energy metering (NEM), energy efficiency, demand response, and more
