Let’s make solar bigger in Massachusetts

What Massachusetts homeowners pay per kilowatt-hour

Rates vary by utility across Massachusetts. The figures below are all-in — supply plus delivery plus riders — not the supply rate alone, because the supply rate is only part of what you actually pay.

• Eversource — ~30¢
• National Grid — ~30¢
• Unitil — see state page

Full detail for each utility is on its own rate page, updated when the utility resets.

Why Massachusetts rates keep climbing

Every Massachusetts utility buys wholesale power through ISO New England. 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 homeowners carry that gap on the delivery side of the bill.

That is the case for solar here: it fixes part of a cost that has otherwise moved in one direction. A power purchase agreement means no upfront payment — we install and own the system, you buy the power it produces at a set rate, and you keep buying whatever you still need from your utility.

Solar in Massachusetts after the federal credit

The federal residential purchase credit ended for systems bought after December 31, 2025. Anyone still advertising it is running an old ad. What remains in Massachusetts is net metering, and under a PPA the tax credit stays with the system owner rather than the homeowner — which is what makes $0 down possible.

Solar Power in Massachusetts

Massachusetts has some of the highest electricity rates in the entire country — which is exactly why it's one of the best states in America to go solar.

Because Massachusetts households pay so much per kilowatt-hour, every unit of power your roof produces delivers outsized savings compared to lower-rate states.

The state's SMART program (Solar Massachusetts Renewable Target) is among the most generous incentive structures in the nation, providing per-kilowatt-hour payments to homeowners who go solar.

Massachusetts has also historically offered a state income tax credit for residential solar, and the state exempts solar from added sales and property tax.

Net metering credits your excess production, and with high rates those credits are worth more here than almost anywhere else.

From Boston and Worcester to Springfield, Cambridge, and Cape Cod, Massachusetts homeowners consistently see strong returns from solar — and battery storage keeps the lights on during the region's nor'easters.

Homeowners who purchase their system could historically receive a federal tax credit of up to 30% of the cost — though the federal residential credit ended for systems purchased after December 31, 2025, so current availability depends on ownership structure, state programs, and current law.
