Municipalities can own distribution in Massachusetts.

Fortty-one municipal electric companies serve 50 municipalities, out of 351 municipalities in Massachusetts.

Via Mass. Municipal Wholesale Electric company, these municipalities have long term contracts and partial ownership of base load nuclear plants, and conventional fossil fuel plants, peaking plants and Solar production sites and a Hydro Quebec sourcing agreement on power lines MMEC has transport rights for. The MMWEC rates will be steadier and have smaller rise than in commercial electric company territories in Massachusetts. Some Vermont utilities are partners with MMWEC projects.
