Which utility serves my address in Massachusetts?

Massachusetts is served by National Grid, Eversource. Your bill names your utility at the top. Service maps do not follow county or town lines, so if your bill does not match what you expect, call (832) 263-8055 and we will check your exact address.

What is an all-in electricity rate?

The all-in rate is your total bill divided by the kilowatt-hours you used. It includes supply, delivery and riders, not the supply rate alone. It is the number that matters when comparing against solar, because solar offsets everything you would otherwise buy.

Can I still claim the 30% federal solar tax credit in Massachusetts?

The 30% federal Residential Clean Energy Credit under Section 25D ended for property placed in service after December 31, 2025. Homeowners buying with cash or a loan in 2026 cannot claim it. Section 48E still applies to third-party-owned systems such as leases and power purchase agreements, where the system owner claims it.

Why do Massachusetts electricity rates keep rising?

Utilities buy wholesale power through a regional grid operator. When capacity and energy prices rise there, they land across the state at roughly the same time rather than utility by utility. Demand from data centers is arriving faster than new generation is being built, and that gap shows up on the delivery side of the bill.

Estimate what solar does against your Massachusetts electric bill

Enter your bill and we’ll size the array that would cover it, and show the gross value of that production at your rate. It does not net off the customer charge, taxes or what you would still draw at night — for that, use the bill savings calculator. Nothing is sent anywhere; this runs in your browser.

How Massachusetts works

Why the number is what it is

Massachusetts law requires utilities to reset basic service supply twice a year, on 1 February and 1 August. Only about a quarter of households are actually on basic service — the rest are on municipal aggregation or a competitive supplier.

Massachusetts residential customers pay roughly 30 cents all-in, about 67% above the national average. New England leans heavily on natural gas for both heating and generation.

The honest cost picture

Two ways to pay for solar

If you buy the system you own the equipment, keep any renewable credits, and carry maintenance. If you use a PPA it is $0 upfront — we install and own the system, you buy the power it produces, and you only pay for what it actually generates.

The residential federal tax credit (25D) ended for property placed in service after December 31, 2025.

You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional.
