Nashua Electricity Prices
Electricity in Nashua costs more than most of the country — and rates have been anything but stable in recent years.
New Hampshire electricity rates rose from 19.9¢ per kWh in 2021 to a peak of 28.2¢ in 2023, before settling at 23.3¢ in 2024 — still well above the national average of 16.5¢.
In response to rising utility costs, many Nashua homeowners have turned to solar as a way to generate their own electricity and reduce their dependence on the grid.
Because solar locks in a more predictable energy cost over time, it can serve as a long-term buffer against future rate increases — giving homeowners more stability in their monthly budgets.
Price of Energy: New Hampshire vs National Average
Nashua Area Utility Providers
In Nashua, NH, Eversource is the primary electricity provider. Based on 2023 data — the most recent available — Eversource customers pay 28.9¢ per kWh, slightly above New Hampshire’s 2023 state average of 28.20¢ per kWh.
Eversource’s 2023 rate is nearly double the 2023 national average of 16.0¢ per kWh. New England’s higher costs stem from aging grid infrastructure, limited pipeline capacity, and heavy reliance on natural gas — factors that consistently push regional rates above the national norm.
When local electricity costs are this high, generating your own power through solar panels in Nashua can reduce how much you draw from the grid — potentially lowering your monthly energy bill over the long term.

New Hampshire Solar Incentives
Nashua homeowners have access to meaningful solar incentives in New Hampshire that can help reduce the overall cost of going solar — especially when adding battery storage.
Eversource customers in Nashua may qualify for a battery storage rebate of $230 per kWh of enrolled capacity, up to $3,000. This rebate is administered through the NH Clean Energy Fund and is available to residential Eversource customers.
Homeowners who lease solar through Palmetto’s LightReach program may find the incentive process simpler — Palmetto handles the commercial tax credit and passes savings along through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Eversource Connected Solutions Battery Storage Rebate | Rebate | Eversource residential customers can receive $230 per kWh of enrolled battery storage capacity (capped at $3,000) through the Connected Solutions demand response program, administered by the NH Clean Energy Fund. | Learn More |
The Eversource Connected Solutions Battery Storage Program, administered in partnership with the New Hampshire Clean Energy Fund (NHCEF), provides residential Eversource customers in Nashua with an upfront rebate of $230 per kWh of battery capacity enrolled in the program, capped at $3,000 per residential account. Commercial accounts can receive $250 per kWh, up to $10,000. The rebate is paid by check once your battery receives permission to operate from Eversource’s interconnection group and is accepted into the demand response program.
To qualify, your battery storage system must have been purchased after October 1, 2022, and you must agree to participate in demand response events for a minimum of three years. During demand response events — which occur between June 1 and September 30, from 3:00 PM to 8:00 PM — Eversource may draw on your battery’s stored energy to help manage grid demand. You can expect approximately 40 events per summer, each lasting no longer than three hours. Eligible battery models include Sonnen eco (Gen 2+), ecoLinx, sonnenCore, sonnenCore+, Enphase IQ Batteries, FranklinWH aPower, and other approved models.
Note that this program has limited funding — as of late 2024, remaining funds were approximately $750,000, so availability may be restricted. This incentive is only available to Eversource NH customers. Contact Eversource or visit their website to confirm current funding availability and to begin the enrollment process.

Leasing Solar Panels
If you’d prefer not to pay the full cost of a solar system upfront, Palmetto offers an alternative through its LightReach program. In Nashua, NH, LightReach is available as a Power Purchase Agreement (PPA) for customers of Eversource Energy, Unitil Energy Services, and Liberty Utilities. (Note: NH Electric Cooperative customers are not eligible for LightReach.)
With a solar PPA, you don’t own the panels — Palmetto does. Instead of paying a fixed monthly amount, you agree to purchase the electricity your system generates at a set rate per kilowatt-hour (kWh). Because solar panels produce more power in summer than winter, your PPA payments will naturally be a bit higher in summer months and lower in winter — though your annual savings average out similarly to a lease. Either way, you’re paying for the power you use, not the equipment itself. You can learn more about the differences between buying and leasing solar here.
Compared to a cash purchase, a PPA through LightReach has a few clear advantages: there’s no large upfront investment, and Palmetto handles all system maintenance and monitoring. If something goes wrong with the panels, that’s Palmetto’s responsibility — not yours. For many Nashua homeowners, this makes going solar simpler, more predictable, and more accessible from day one.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!
