Community Choice Aggregation

Community Choice Aggregation (CCA) is a process by which municipalities can aggregate and switch the electricity of the households and small businesses from basic service over to cleaner energy. An energy broker is employed to ensure the municipality can purchase the amount of energy needed, and residents may opt out at any time. The electricity is still distributed and billed through the original utility (i.e. Eversource). 

What is the Benefit of CCA?

By using community choice aggregation, a town can very efficiently effect a change in how energy is produced. 

While developing an aggregation plan with the help of the energy broker, a town chooses several options for energy mixes, with defined percentages produced from renewable sources (e.g., wind, solar). These options can be formulated based on resident feedback, and effectively provide choice as well as fiscal control in the form of stable, predictable rates to individual residents, typically including one option that closely resembles the current energy mix and pricing. 

Several examples from surrounding towns show that residents can save money on their electricity bills while receiving more power from renewable sources than the state-mandated 14%. Acton, Lexington, Natick, Newton, Sudbury, and Watertown are among the municipalities in our area that have already implemented CCA, and Lincoln has begun their process. 

How is CCA Implemented?

The process of implementing community choice aggregation is strictly governed by Massachusetts regulations, and the first step is a Town Meeting vote authorizing the town to pursue it (with no commitment to implement it). An article will be on the warrant for Special Town Meeting on Tuesday, December 3, 2019.
