Best Electricity Rates in New Hampshire 2026: How to Compare Suppliers and Save

New Hampshire consistently ranks among the states with the highest electricity rates in the nation — and has had a deregulated electricity market since 1996, one of the earliest in the country. If you’re served by Eversource, Liberty Utilities, or Unitil in New Hampshire and haven’t compared electricity suppliers recently, you may be paying the utility’s default rate when a competitive supplier could offer you a better deal. Here’s exactly how the New Hampshire electricity market works and how to find the best rate in 2026.

New Hampshire’s Electricity Deregulation: A Pioneer Market

New Hampshire passed its Electric Utility Restructuring Act in 1996, making it one of the first states in the country to open its retail electricity market to competition. The law separates electricity generation from delivery — your local utility continues to own and operate the power lines (and is responsible for outage response), but you can choose who supplies the electricity flowing through those lines.

If you’ve never chosen a supplier, you’re on your utility’s “default service” — a rate set by the New Hampshire Public Utilities Commission (NHPUC) through periodic procurement. Default service rates in New Hampshire change frequently (often every 6 months or quarterly) and are directly tied to New England’s ISO-NE wholesale market prices, which are heavily influenced by natural gas costs.

New Hampshire’s Utilities

Eversource Energy (formerly Public Service of New Hampshire) is the largest utility in the state, serving customers in the Seacoast region, southern New Hampshire, Manchester, Nashua, and surrounding communities. Eversource NH customers have the most competitive supplier options.

Liberty Utilities serves northern New Hampshire and some central areas. Liberty’s territory includes communities around Concord and extends into the Lakes Region and North Country.

Unitil serves smaller customer bases in portions of southern New Hampshire. Unitil customers in NH also have access to competitive suppliers.

Each utility has a separate default service rate set independently by the NHPUC. Always compare against your specific utility’s current default rate — not a statewide average.

New Hampshire Electricity Rates in 2026

New Hampshire residential electricity costs are persistently high — all-in rates (supply + delivery) typically run 22–30+ cents per kWh depending on the utility and season. New Hampshire sits on the ISO-NE grid, which is heavily dependent on natural gas for electricity generation. When winter heating demand spikes gas prices, electricity rates follow — sometimes dramatically, as seen during the 2022–2023 winter when default service rates hit record highs in parts of New England.

In 2026, default service rates have moderated from their peaks but remain elevated. Competitive suppliers are offering fixed-rate plans in the 12–17 cents per kWh range for supply-only in most NH utility territories. Whether a competitive rate beats the current default depends on the moment you shop — compare on the day you plan to enroll, not weeks earlier.

Types of Plans Available in New Hampshire

Fixed-rate plans lock your supply rate for a term (typically 6, 12, or 24 months). These are the dominant offering in New Hampshire’s competitive market and the right choice for most households. Given NH’s volatile ISO-NE pricing, a fixed rate provides genuine protection against mid-winter spikes. Locking in a fixed rate before winter heating season is particularly strategically valuable in New Hampshire.

Variable-rate plans track wholesale market conditions monthly. In favorable seasons, variable rates can be lower than fixed — but in New England winters, variable rates can spike sharply. For most New Hampshire households, fixed rates provide better risk management than variable plans.

Green energy plans are available from several NH-licensed suppliers. New Hampshire has a Renewable Portfolio Standard requiring increasing renewable content from utilities and suppliers. 100% renewable plans from competitive suppliers are available, sometimes at only small premiums over non-renewable fixed plans.

How to Switch Electricity Suppliers in New Hampshire

Step 1: Find your default service rate. Your Eversource, Liberty, or Unitil bill shows the “Default Service” or “Generation” charge in cents per kWh. This is your current supply rate and the benchmark you’re trying to beat.

Step 2: Compare licensed competitive suppliers. Enter your New Hampshire ZIP code and utility name in a comparison tool. Focus on fixed-rate supply offers — compare the rate per kWh to your current default service charge.

Step 3: Read the offer disclosure. New Hampshire requires all competitive suppliers to provide disclosure of rates, fees, contract terms, and auto-renewal provisions before you enroll. Pay attention to the early termination fee (ETF) and auto-renewal terms.

Step 4: Enroll. Online enrollment takes 5–10 minutes and requires your utility account number. The switch takes effect within 1–2 billing cycles — no service interruption occurs.

Step 5: Monitor your bill. Your utility continues to deliver power and send your monthly bill. The supply charge line will reflect your new supplier’s rate. Confirm it matches your contract on the first post-switch statement.

New Hampshire Consumer Protections

The NHPUC licenses all competitive electricity suppliers. Protections for New Hampshire electricity shoppers include a mandatory disclosure before enrollment of all rates, fees, and contract terms; a right to cancel within 3 days of signing with no penalty; prohibition on slamming (switching without consent); and automatic return to default service if your supplier exits the market or loses its license. The NHPUC also maintains a consumer complaint process.

Frequently Asked Questions About NH Electricity Choice

Why are New Hampshire electricity rates so high?

New Hampshire sits in the ISO-NE power pool, which relies heavily on natural gas-fired generation (40–50% of regional electricity in many years). New England has limited pipeline capacity to bring in natural gas during winter, which creates severe price spikes during cold snaps. The region also has high transmission and distribution costs due to its aging infrastructure and geography. These structural factors keep NH rates consistently above the national average.

Is the savings opportunity in NH significant?

It can be. During 2022–2023, New Hampshire customers who locked in fixed competitive rates before winter saved hundreds of dollars compared to customers who stayed on rapidly escalating default service. Even in more stable years, a 1–2 cent per kWh reduction in supply rate saves a typical 800 kWh/month household $96–$192 annually. Given NH’s elevated total rates, the supply savings have real impact on household budgets.

Can I switch suppliers in New Hampshire more than once?

Yes. You can switch as many times as you want — including returning to default service. The main constraint is ETF if you break a fixed-rate contract early. Plans with no ETF or short terms give you the most flexibility to re-shop when better rates emerge.

What happens if my supplier goes out of business?

You’re automatically returned to your utility’s default service — your power never goes out. The transition is handled between your supplier, your utility, and the NHPUC without any action required from you.

Should I lock in a long-term contract in New Hampshire?

Given NH’s exposure to winter price spikes, longer fixed-rate terms (12–24 months) are generally worth considering if the rate is competitive. A 24-month lock at a good rate provides two full heating seasons of price certainty in a market where default service has swung dramatically year to year. The main risk of a long-term lock is if market rates fall significantly — you’re stuck paying the higher locked rate. Evaluate based on your assessment of where energy prices are headed.

Should New Hampshire Residents Shop for Electricity?

Given New Hampshire’s consistently high rates, its exposure to New England winter price volatility, and the fact that it has had an open market for nearly 30 years, shopping for electricity is one of the more impactful cost-management moves available to NH households. The process takes 10–15 minutes, costs nothing, and is protected by NHPUC regulation. If you’re on default service and haven’t compared in the past 12 months — particularly if winter is approaching — it’s worth checking what’s available.
