We provide expert guidance to a network of over 8,000 energy professionals including local, state, and federal governments, non-profits, trade associations, advocacy groups, and private sector partners.​
Community Choice Aggregation (a.k.a. CCA*) is a state-enabled local energy model that allows municipalities and counties to aggregate the electricity demand of their communities. While utilities continue to deliver electricity and maintain grid infrastructure, CCAs take over the energy procurement function by purchasing and/or developing power on behalf of residents and businesses.
These programs have become so popular that participation in active CCA communities typically ranges between 85% and 95%. CCA is now one of the most powerful local policy tools local governments can use to drive energy independence, protect consumers, prioritize competitive pricing, and develop local economic benefits.
_______
*The term “Community Choice Aggregation” is commonly used across the U.S., however, some states may refer to this model by "Community Choice Electricity", "Community Choice Energy", "Community Power Aggregation", "Community Energy Aggregation", "Local Choice Energy", "Government Energy Aggregation", etc.
According to a recent study by NREL, CCA programs were the fifth largest procurement structure for U.S. voluntary renewable power in 2023 and represented approximately 60% of all U.S. voluntary green power market customers.
How "Community Choice Aggregation" Works
buying and/or building electricity supply
delivering energy, maintaining lines,
billing customers
benefitting from affordable rates, local control, cleaner energy
Since 2011, our 501(c)(3) nonprofit organization has advanced community choice energy programs by supporting competition, customer choice, and affordable electricity rates across the country.
