Is Reading in Mass Save?

Partly. Reading is a municipal light plant town: its electricity comes from the Reading Municipal Light Department, and light plant customers are outside Mass Save's electric program. National Grid, an investor-owned gas company, also serves the town, so a home with a National Grid gas account can use Mass Save through it.

For weatherization, a National Grid gas account is enough, even one that only heats water. A home with no gas service uses the light plant's own programs.

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

Do you need a permit for replacement windows or doors in Reading?

Plan on one.
