Nashua Electricity Prices

Electricity in Nashua, NH costs more than most homeowners realize — and it’s worth understanding what that means for your household budget.

New Hampshire electricity rates have climbed significantly in recent years. In 2021, Nashua-area residents paid around 19.9 cents per kWh. By 2023, that figure had risen to 28.2 cents — well above the 2024 national average of 16.5 cents per kWh.

Solar panel installation gives Nashua homeowners a way to generate their own electricity, reducing how much they draw from the grid. When local rates are this high, producing your own power has a measurable impact on monthly energy costs.

Over time, a solar system can help stabilize what you pay for energy — regardless of where New Hampshire electricity rates go next. For many Nashua households, that long-term predictability is one of the most practical benefits of going solar.

Nashua Area Utility Providers

Nashua homeowners are served by Eversource, whose 2023 electricity rate was 28.9¢ per kWh — well above the 2023 national average of 16.0¢ per kWh. (2023 is the most recent data available.)

Eversource’s high rates reflect challenges common across New England: aging grid infrastructure, heavy reliance on imported fossil fuels, limited pipeline capacity, and regional transmission costs that consistently push prices above national norms.

When local electricity costs this much, it’s worth understanding your alternatives. Generating your own power through solar can meaningfully reduce what Nashua homeowners send back to the grid each month.

New Hampshire Solar Incentives

Nashua homeowners can take advantage of available solar incentives in New Hampshire to help offset the cost of solar installation.

The Eversource Connected Solutions Battery Storage Demand Response Program offers eligible homeowners an upfront rebate of $230 per kWh of enrolled battery capacity — up to $3,000 — through the New Hampshire Clean Energy Fund.

Incentive Type Description Source
Eversource Connected Solutions – Battery Storage Demand Response Program Rebate Eversource offers residential customers in Nashua an upfront rebate of $230 per kWh of enrolled battery capacity (up to $3,000) through the New Hampshire Clean Energy Fund (NHCEF) in exchange for participating in demand response events. Learn More

Eversource’s Connected Solutions Program, administered through the New Hampshire Clean Energy Fund (NHCEF), provides residential customers in Nashua with an upfront incentive 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 as a check once your battery has received permission to operate from the interconnection group and has been accepted into the demand response program. Eligible battery manufacturers include Enphase, FranklinWH, and other approved models.

In exchange for the rebate, participants must allow Eversource to access their battery during periods of peak electricity demand for a minimum of three years. Demand response events occur from June through September, between 3:00 PM and 8:00 PM, with approximately 40 events per summer, each lasting no longer than three hours. During these events, your stored battery power helps reduce strain on the grid and displaces the need for polluting peaker plants.

To apply, Eversource customers can email [email protected] or visit the official program page. Participants may also be eligible for low- or zero-interest financing through the National Energy Improvement Fund (NEIF) to help cover the cost of battery installation. Note that the state’s municipal property tax exemption may also apply to your battery storage system, further reducing your overall cost.

Leasing Solar Panels

If you’re a Nashua homeowner interested in solar but not ready to pay the full cost upfront, Palmetto offers a Power Purchase Agreement (PPA) through its LightReach program. A PPA is available to customers served by Eversource Energy, Unitil Energy Services, and Liberty Utilities in New Hampshire — which covers the majority of Nashua households.

With a solar PPA, you don’t purchase the system — Palmetto does. Instead, you agree to buy the electricity your panels produce at a set rate per kilowatt-hour (kWh). Because solar panels generate more power in summer than winter, your monthly solar bill will naturally vary with the seasons. That said, your annual savings tend to be consistent. Palmetto also handles all system maintenance, so there’s nothing to manage on your end. Learn more about how a PPA compares to buying solar outright.

Compared to a cash purchase, a PPA means no large upfront investment and no responsibility for repairs or monitoring. Palmetto owns the system and keeps it running — you simply use the power it produces and pay for what you generate, typically at a rate below what you’d pay your utility.

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!

Frequently Asked Questions

Yes, solar makes strong sense for Nashua homeowners. New Hampshire electricity rates average 23.33¢/kWh — well above the national average — and Nashua receives about 4.6 peak sun hours per day, enough to generate meaningful savings year-round. A typical home can save around $66,000 over 25 years with an estimated payback period of about 11 years.

If upfront cost is a concern, Palmetto’s LightReach solar lease removes that barrier entirely — Nashua homeowners can go solar with no money down and start saving from day one, with payments starting as low as $122/month and all maintenance included.

Yes, Nashua has net metering. Most Nashua homeowners are served by Eversource Energy, which offers monthly net metering. Each month, excess solar energy you send to the grid is credited at roughly ~21¢ per kWh (2023). Unused credits roll over year to year, and you can request a cash payment after the March billing cycle if your balance exceeds $100.

Customers using a competitive retail electricity supplier may not qualify for the full Default Energy Service portion of the credit. If you’re served by Liberty Utilities or Unitil instead, similar monthly net metering programs apply with slightly different credit rates.

Yes, solar panels can increase your home value in Nashua. According to a Zillow study, homes with solar panels sell for approximately 4.1% more than comparable homes without them. For a $400,000 home in Nashua, that could mean roughly $16,400 in added value.

With New Hampshire electricity rates averaging 23.33¢/kWh — well above the national average — buyers recognize the long-term savings that come with an owned solar system, making solar-equipped homes more attractive in the Nashua real estate market.

The most accessible way for Nashua homeowners to go solar is through Palmetto’s LightReach lease — with no upfront cost and a low fixed monthly payment starting around $122/month for a typical home. Palmetto owns and maintains the system, so there’s nothing to manage.

For those who prefer a cash purchase, a typical Nashua system costs around $24,580 for a medium-sized home. Note that the federal 30% tax credit is no longer available for residential cash purchases following the Big Beautiful Bill. Use the calculator above for your specific estimate.

For Nashua homeowners, solar can make strong financial sense — especially with electricity rates averaging 23.33¢/kWh, well above the national average. A typical home can save around $66,000 over 25 years on a cash purchase.

But you don’t need to invest upfront to start saving. With Palmetto’s LightReach lease, your monthly solar payment is typically less than your current electric bill — starting as low as $122/month — with no upfront cost and all maintenance included. Many Nashua homeowners see savings from day one.
