Six states – California, Illinois, Massachusetts, New Jersey, Ohio, and Rhode Island – have CCA legislation enabling local governments to aggregate the electricity loads of residents, businesses, and municipal facilities.
CCA programs use aggregated demand and group purchasing to achieve local objectives including consumer rate savings, greenhouse gas reductions, new revenues for local energy programs, utility reform, and jobs creation. CCAs reflect the values of their governing boards and the communities they serve.
- California has the first climate-driven CCA in the nation. It provides 67% greenhouse gas-free power, a 100 percent renewables option, and robust net metering and feed-in tariff programs. Since 2011, it has contracted for nearly 60 MW of new solar, wind, biomass and landfill gas energy. In addition to Marin County and the City of Richmond, California also has CCAs certified in Sonoma, and San Francisco. CCAs are underway in Monterey Bay (Monterey/Santa Cruz), and several East Bay cities, San Diego, and Yolo County are exploring CCA as an option.
- Illinois has experienced the fastest rate of CCA adoption, driven primarily by rate savings of 25%-30% through June, 2014. Over 600 municipalities have passed aggregation referenda since 2011, including the City of Chicago which now has the largest program in the Country.
- Massachusetts has the longest-running CCA. Operational since 1997, Cape Light Compact serves over 200,000 customers, administers energy efficiency programs, and advocates for customers at the legislative and regulatory levels. Through the Cape & Vineyard Electric Coop, Cape Light has partnered on over 36MW of new solar built on multiple sites throughout Cape Cod and Martha’s Vineyard. As of October, 2014, Massachusetts has 19 approved municipal aggregations which include 39 municipalities. In addition, 35 municipalities are currently seeking approval of their respective municipal aggregation plans.
- Ohio’s NOPEC, the nation’s largest CCA with 500,000 customers in 10 counties, has achieved a rate savings of $175 million since 2001. Over 250 additional communities in OH are being served by both gas and electric aggregation. The City of Cincinnati was the first city in Ohio to green their supply using 100% renewable energy credits.
- Rhode Island has a single aggregation, run by the Rhode Island Energy Aggregation Program of the RI League of Cities. REAP facilitates group energy purchasing for the municipal loads of 37 cities and 4 school districts, saving over $30 million in electricity costs since 1999.
- New Jersey’s aggregation market has begun to emerge with 4 communities- Tom’s River, Montgomery County, Monroe, and Plumsted Townships, having switched to aggregation since early 2013. Electricity rate savings of these early adopter programs ranges from 8%-14%, and there are at least 5 additional communities in the planning pipeline.
