Sanford has a new 28-megawatt solar array online, one of the largest installations in southern Maine. The Mousam River Solar Project is built on 140 acres of privately owned parcels of land and can provide enough electricity for 6,000 homes. Jack Kenworthy, Chief Development Officer for Walden Renewables, said it offers the kind of clean energy that grid operator ISO - New England is looking for. Kenworthy said there is a buyer for the power from the project with a large presence in Maine and New England that will be announced early next year.
