Is Groton in Mass Save?

It depends on the address. Part of Groton gets its electricity from National Grid and part from the Groton Electric Light Department (the state's list names both), and Mass Save follows the company that sends the electric bill: a home on National Grid's service is in the Mass Save program, and a home on the light plant's service is outside Mass Save's electric program. A home on the light plant's service can still use Mass Save through a National Grid gas account.

To check, look at the company name on your electric bill, or ask the light plant whether it serves your street.

Groton is on the state's list of municipal light plants; Mass Save in municipal light plant towns has the full decision tree.

Rebates and financing for new siding in Groton

Mass Save doesn't pay for the siding itself: its insulation and windows offers cover insulation, air sealing and windows, and siding is not on the HEAT Loan's list of eligible measures.

For a home on National Grid's electric service, the insulation can be covered: after a Home Energy Assessment, Mass Save pays 75 to 100 percent of approved insulation and air sealing in Groton. Book the assessment before the old siding comes off, while the walls are open.

On the light plant's service, the Mass Save insulation offer goes through a National Grid gas account; a home with no such account uses the light plant's own programs.

Do you need a permit for new siding in Groton?

Plan on one. Residing is not on the Massachusetts building code's list of permit-exempt work, and the Groton Building Department settles the borderline cases. 39% of Groton's homes were built before 1980 (Census ACS 2018-2022), and work that disturbs paint in a home built before 1978 has to follow the lead-safe renovation rules.
