Massachusetts Municipal Wholesale Electric Company (MMWEC), the Commonwealth’s designated not-for-profit joint action agency for municipal utilities, is entering into power purchase agreements with two Maine onshore wind projects.
MMWEC’s Board of Directors has authorized the organization to proceed with executing contracts for the wind energy and associated renewable energy credits.
Twelve MMWEC Member municipal light plants (MLPs) plan to participate in the PPAs with Stetson Wind I and II, located in Danforth, Washington County, Maine. They include the MLPs located in the communities of Boylston, Groton, Holyoke, Ipswich, Marblehead, Peabody, Princeton, Shrewsbury, Sterling, Templeton, Wakefield and West Boylston.
Stetson Wind I is a 38-turbine, 57-megawatt project which reached commercial operation in 2009. Stetson Wind II is a 17-turbine, 25.5 MW project which reached commercial operation in 2010. The projects are owned and operated by TerraForm Power.
The PPA is a five-year agreement, commencing in January 2026, for approximately 12 MW/42,196 megawatt hours of capacity from Stetson Wind I and II. MMWEC’s offtake represents 18.6% of Stetson I and 20% of Stetson II.
The agreement provides participating MLPs with unit-specific wind power and the associated unit-specific Class I renewable energy credits. The Stetson projects are strong inland wind resources, operating at a capacity factor of approximately 40%.
“This agreement will provide participating MLPs with a reliable source of renewable energy while supporting MLP clean energy goals,” said MMWEC CEO Tom Barry. “This agreement demonstrates the commitment of MMWEC and its Project Participants in proactively decarbonizing their power portfolios.”
MMWEC is a not-for-profit, public corporation and political subdivision of the Commonwealth of Massachusetts created by an Act of the General Court in 1975 and authorized to issue tax-exempt debt to finance a wide range of energy facilities.
MMWEC provides a variety of power supply, financial, risk management and other services to the state’s consumer-owned, municipal utilities. It is the largest provider of asset-owned generation for municipal light departments in New England.
