"New England Council (NEC) members Blue Cross Blue Shield of Massachusetts and Ameresco are celebrating the opening of five new solar farms across Massachusetts.

"Three of the projects are on the 650-acre Twin Elm Farm in Mendon and the other two are in Hopedale.  The projects hold a combined 6.9 megawatts of renewable power and will increase solar production in Massachusetts by 13%, lower carbon emissions and help almost 200 local residents and businesses to lower their electricity bills.  The solar farms are owned by Ameresco, co-developed by BlueWave Solar and supported by Blue Cross Blue Shield, which purchased 2.6 MW of net metering credits that will be applied to its utility bills. The opening of the solar farms was celebrated with ribbon cutting at the Twin Elm Farm in Mendon in August 2017.

“'Community solar projects like these allow local citizens and businesses to benefit directly from the energy produced by these projects,' said Michael T. Bakas, Senior Vice President, Ameresco. 'We are honored to support Blue Cross, a leader in providing high-quality health care, in their efforts to positively impact the environment. Their commitment to sustainability and environmental stewardship is a model for all to follow.”'
