Why the number is what it is
What is actually driving this
Two increases in one year
Eversource raised basic service 5.01% on February 1, 2026 — from 14.884¢ to 15.629¢ — then another 10.8% on August 1, to 17.32¢. Massachusetts law fixes those reset dates.
New England gas dependence
Eversource attributes the increase to market conditions: an unusually cold winter driving gas demand, and international instability straining energy markets. The utility earns no profit on the supply charge itself.
Grid and clean energy investment
Infrastructure upgrades and clean energy commitments are recovered through rates over time.
The honest cost picture
Two ways to pay for solar, and they are very different
If you buy the system
You own the equipment, you keep any renewable energy credits, and you carry the maintenance responsibility. Installed pricing varies by roof, shading and system size.
If you use a PPA
$0 upfront. We install and own the system; you buy the power it produces at a rate set in your agreement, and you only pay for what it actually generates. The system owner carries maintenance for the life of the agreement.
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 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.

Eversource questions
The things people actually ask
Am I affected by the August increase?
Only if you are on basic service. About 26.6% of Massachusetts customers were as of March 2026; the rest are on municipal aggregation or competitive supply. Check the supply line on your bill.
Why did rates rise twice in 2026?
Massachusetts law requires supply rates to reset in February and August each year. Both 2026 resets moved up — 5.01% in February and 10.8% in August.
Does solar work in Massachusetts winters?
Yes. Panels generate from light rather than heat and are more efficient when cold. At roughly 30 cents per kilowatt-hour, the economics here beat plenty of sunnier states.
