You do not choose your utility — it is set by your address. This is context, not an option.
Why it is high
Three causes, in the order worth checking
Usage
Pull twelve months of kilowatt-hours from your Eversource Massachusetts account. Dollars hide whether the problem is how much you use or what you pay for it. Electric heat, a heat pump in shoulder season, an EV or a second refrigerator will all show up here.
Rate increases
Rate changes are filed with the state commission and take effect on a published schedule. Your bill will note the reset.
Your supplier
You can buy supply from a third party while Eversource Massachusetts still delivers it. A supplier contract that rolled off a teaser rate onto a variable one is the most common cause of a bill that jumped with no change in usage. Compare the supply line against the Eversource Massachusetts default rate.
What a roof does against it
Production against a 30.0¢ rate
This part of Massachusetts averages about 4.0 peak sun hours a day, so a kilowatt of panels produces roughly 1,168 kilowatt-hours a year. A 9 kW system makes around 10,512 kilowatt-hours annually — about $3,154 of Eversource Massachusetts electricity a year at the current rate.
That is production value, not a savings figure. What you actually keep depends on how much of it you use directly versus export, what Eversource Massachusetts credits exports at, and what you pay for the system. Under a power purchase agreement there is no upfront cost and you buy the production at an agreed rate instead.
The residential federal tax credit (25D) ended for systems purchased after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. If you buy a system today as a homeowner, you cannot claim that credit. What remains under 48E applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional about your situation.
Every figure here is an estimate built from published rates and modeled production. It is not a savings guarantee, and no solar company can honestly give you one. Your actual result depends on your roof, your usage and what your utility charges next year.

Questions
The things people actually ask
Why is my Eversource Massachusetts bill so high?
Eversource Massachusetts residential service runs about 30.0¢ per kilowatt-hour all-in, so 1,000 kilowatt-hours costs roughly $300 before fixed charges. If your usage has not changed and the bill has, the cause is the rate or your third-party supplier contract.
How much is Eversource Massachusetts per kWh?
About 30.0¢ all-in as of August 2026, combining supply, delivery and riders. Your own bill divided by your kilowatt-hours is the exact figure for your account.
Can I switch away from Eversource Massachusetts?
Not for delivery — that is set by your address. You can buy supply from a third party while Eversource Massachusetts still delivers it.
Would solar cover my whole bill?
Almost certainly not all of it. You stay connected, you keep a customer charge, and you draw at night. Solar offsets a portion of usage, and how large a portion depends on your roof.
