Utility rules and programs for Somerville
Eversource serves homes in Somerville.
| Utility | Type | Generator rules |
|---|---|---|
| NSTAR Electric Company | investor-owned | A generator transfer switch or battery hookup is electrical work that needs a licensed electrician and an electrical permit from your local wiring inspector under the Massachusetts Electrical Code (527 CMR 12.00); ask your town for local rules. |
Program details are from each utility’s own pages (read October 2026). See the Massachusetts incentives table for statewide credits and a status for every program.
What to plan for in Somerville
- Ice storms (very high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
