default Community Choice Aggregation (CCA) is a State Policy Popular

By In Community Choice Aggregation 1046 downloads

Community choice aggregation (CCA) is a state policy that enables local governments to aggregate electricity demand within their jurisdictions in order to procure alternative energy supplies while maintaining the existing electricity provider for transmission and distribution services. Many states passed CCA laws as part of electric restructuring legislation in the late 1990s and early 2000s. States that have passed CCA laws include California (2002), Illinois (2009), Massachusetts (1997), New Jersey (2003), Ohio (1999), and Rhode Island (1997). There are many reasons that a community may choose to develop a CCA, including the option to purchase more green power, reduce electricity cost, and provide power from more local sources.

default COMMUNITY CHOICE AGGREGATION, a Massachusetts program Popular

By In Community Choice Aggregation 1067 downloads

CCA is a program towns and cities can use to switch everyone in the town who is on basic service over to cleaner energy. An energy broker helps the community purchase the amount of energy which best fits their needs. Residents may opt out at any time. The energy is still distributed and billed through the town's original utility (i.e., Eversource or National Grid).  


Community Choice Aggregation allows residents and small businesses to seamlessly switch to more renewable energy.

buyer beware: not all purchases of renewable energy actually reduce GHG emissions! The key is “additionality” – evidence that such extra purchases actually helped add more renewable energy to the grid. In other words, the quantity of renewable energy purchased is not as important as the impact of that purchase on the grid.
