Community Choice Aggregation (CCA), authorized by the California legislature in 2002, gives cities and counties a mechanism to move away from dirty energy, provide savings for residents and support local economic development. A CCA can negotiate a price for electricity from current renewable sources or develop new renewable generating capacity in the community. The existing utility company for the area continues to handle transmission, distribution, billing and other administrative matters. Marin County’s CCA, known as Marin Clean Energy, is the only operative one so far. MCE offers two levels of service: Light Green (50% renewable energy sources) and Deep Green (100% renewable sources). The cost for Deep Green averages $5 more per month. MCE is working on plans to develop its own generating capacity, which will contribute to the local economy.
