Community Choice Aggregation

Community choice aggregation (CCA), also known as municipal aggregation, allows local governments to procure power on behalf of their residents, businesses, and municipal consumers from an alternative supplier while still receiving transmission and distribution service from their existing utility provider. This approach grants communities greater control and leverage when negotiating with suppliers, resulting in higher amounts of clean energy consumption and/or lower electricity prices.

Most municipalities that deploy CCA programs purchase a greater percentage of their electricity from renewable power than the default utility services, often at a lower rate than the utility. Participation in CCA programs is voluntary, with most CCAs including all customers by default and offering advanced notice and options to opt-out of service. CCAs can also have a tiered structure with additional price premiums to procure an even higher percentage of electricity from renewables.

To proceed with a CCA program, a state must first pass legislation authorizing local governments to pursue programs in their municipalities. Local governments then must hold public hearings and processes to establish a CCA program, which can be administered by a city or county government, or by a third party through a contractual agreement.
