The Value of MMWEC

The Massachusetts Municipal Wholesale Electric Company (MMWEC) brings a competitive edge to Massachusetts municipal utilities dedicated to providing their customers with low-cost and reliable electricity. We plan, develop and manage energy resources in an evolving marketplace that requires high levels of innovation and expertise. Our values are old-fashioned, reflecting 40 years of public power joint action, but our service is enlightened.

MMWEC's Stony Brook Power Plant is a unique and valuable asset for its municipal utility project participants and ISO New England, which relies upon Stony Brook in several capacities. Read more about Stony Brook's value in the latest issue of MMWEC's Joint Action News, found here.
