Community Choice Aggregation (CCA) is an energy supply model whereby local governments combine their energy loads and make the choice to purchase energy independently instead of from a utility. Therefore, CCA allows local governments to set their own renewable energy targets and potentially deliver a greater range of renewable energy to their customers. As of 2017, CCAs were projected to account for as much as 60% of California’s electricity load by 2020.   The objective of this project is to assess the potential of the CCA model in California to contribute to meeting 100% local, renewable energy by 2050 in Los Angeles County. Through analysis of policy and planning documents, media coverage and interviews, the project explored opportunities and benefits of this innovation in energy governance and service delivery. It also identified future challenges with the CCA model.
