Eversource New Hampshire electric rates and bills

Eversource New Hampshire's price per kWh, with its period

Eversource is the trade name of Public Service Company of New Hampshire, the largest utility in the state: 464,024 homes were on its wires in 2025, 71.7% of New Hampshire's residential customers. EIA's price figures for Eversource cover only the 263,458¹ of them that bought both supply and delivery from the utility, on its default energy service. For those homes:

• the 12 months from September 2025 to August 2026 averaged 26.17¢ per kWh (EIA-861M monthly sample; the 2026 months are preliminary);
• August 2026³ alone averaged 27.24¢ per kWh², one preliminary month;
• the calendar year 2025 averaged 24.17¢ per kWh¹ (EIA-861, final).

Each is average revenue per kWh: what the group paid Eversource in total, customer charge, distribution, transmission, energy service and other charges together, divided by the kWh it used. Most taxes are left out. The energy service rate that Eversource publishes and prints on bills is the supply part alone, so it is lower than these averages; the two are different measures, not competing answers.

Within New Hampshire, Eversource's 2025 average was the 2nd highest of the 4 utilities with 10,000 or more full-service residential customers, 1.5% below the New Hampshire average. Nationally it ranked 18th highest of 177 large utilities and was 35.9% above the national average for investor-owned utilities¹.

From 2024 to the last 12 months: a steady climb

The annual figures show the first step. Eversource's energy-service average went from 22.65¢ per kWh in 2024 to 24.17¢ per kWh in 2025, up 6.7%. The average bill rose faster, from $136.15 to $149.82 (+10.0%), because use per home also grew, from 601 kWh⁴ to 620 kWh¹ a month.

The monthly sample shows the rise continuing into 2026. The 12 months from September 2025 to August 2026 averaged 26.17¢ per kWh, and the average bill over those months was $162.37 for 620 kWh: the same use as in 2025, so the higher bill came from the price. In August 2026³ the average reached 27.24¢ per kWh, +10.0%² on August 2025.

Eversource was not alone. Across all New Hampshire providers the 12-month residential average rose 13.8% on the 12 months before, the 2nd highest increase among the 50 states and DC, against 6.5%³ nationally. EIA's figures record the size of the change, not its cause; the charges themselves are set in proceedings before the New Hampshire Public Utilities Commission, which approves Eversource's energy service rate and decides its rate cases.

Energy service, suppliers and Community Power: two groups of homes

43.2% of the residential customers on Eversource's wires, 200,566 homes, bought their supply elsewhere in 2025: from a competitive supplier or through a Community Power program, which buys supply for the residents of member towns. Across the state, the Community Power Coalition of NH alone served 169,038¹ residential customers that year. For these homes Eversource bills delivery only, and EIA reports a separate average for them:

• Energy service (bundled): 24.17¢ per kWh in 2025, supply and delivery together, for 263,458 homes; average bill $149.82 for 620 kWh a month.
• Delivery only: 14.20¢ per kWh in 2025, Eversource's charges alone for 200,566 homes; average delivery bill $92.72 for 653 kWh¹ a month. The supplier's or Community Power's charge is billed on top and is not in Eversource's figures.

The two averages describe different homes and different parts of a bill, so they are shown side by side and never added. The delivery-only average rose from 13.12¢ per kWh⁴ in 2024 to 14.20¢ per kWh (+8.2%): whichever supplier a home chooses, this part changed for everyone on Eversource's wires. Statewide, suppliers and Community Power billed residential customers an average of 11.83¢ per kWh¹ for supply only in 2025, a past average over every contract in force that year, not a price on offer today.

Among Eversource Energy's 3 utilities, New Hampshire's delivery-only average was the lowest in 2025; Massachusetts averaged 20.06¢ per kWh and Connecticut 18.65¢ per kWh. The share buying supply elsewhere sat between the two: 75.9% in Massachusetts, 16.6%¹ in Connecticut.

Winter sets the largest bills

Eversource's New Hampshire homes use the most electricity in the cold months, unlike its Connecticut customers, whose peak came in July 2026. Over the 12 months from September 2025 to August 2026, use per energy-service home ranged from 457 kWh in September 2025 to 796 kWh in January 2026, and the average bill in those two months from $132.90 to $202.27². Even the peak month is modest by national standards: US homes averaged 874 kWh⁵ a month across all of 2025.

Eversource beside Unitil, the Co-op and Liberty

Four utilities deliver power to almost every New Hampshire home, each in its own territory. In 2025, Unitil Energy Systems had the lowest full-service residential average among them (21.72¢ per kWh) and New Hampshire Electric Cooperative the highest (24.70¢ per kWh); Eversource, at 24.17¢ per kWh, sat between them, close to the investor-owned average for the state (23.85¢ per kWh¹). The bill comparison below adds use per home to the price.

EIA's 2025 territory records place Eversource in all 10 New Hampshire counties: Belknap County, Carroll County, Cheshire County, Coos County, Grafton County, Hillsborough County, Merrimack County, Rockingham County, Strafford County and Sullivan County⁶. In every one of them at least one other distribution utility also reports customers, so a town or ZIP code does not settle who serves a home; Eversource's service map does. EIA has no price by town.

Within Eversource Energy, the New Hampshire full-service average fell between its sister utilities in 2025: 28.88¢ per kWh in Connecticut and 21.49¢ per kWh¹ in Massachusetts. The Eversource Energy page sets the three side by side.

Smart meters and time-of-use: close to zero

In EIA's 2025 meter count, 0.0% of Eversource's New Hampshire residential meters were advanced meters, the kind that send hourly readings. Because Eversource carries most of the state's homes, New Hampshire as a whole had only 22.1% on advanced meters, the 2nd lowest share among the states. Time-varying pricing follows the meters: Eversource reported time-of-use pricing with 97 residential customers enrolled, 0.0%⁸ of homes on its wires. The time-of-use guide explains how such rates work where they are available.

Rooftop solar is more common. Eversource reported 18,774 net-metered residential installations in 2025, 40.5 per 1,000 residential customers (state: 38.3), with 157.3 megawatts⁸ of capacity. Power those panels make and use on site is not in the kWh-per-home figures above.

Outages: below the state average

Eversource's New Hampshire customers averaged 161 minutes without power in 2025 counting major storms, fewer than the New Hampshire average of 231 minutes, and 83 minutes on days without major events (state: 135 minutes). The average customer had 1.09 interruptions, against 1.45⁹ statewide. Figures follow the IEEE 1366 standard.

Businesses, and help with bills

Full-service commercial customers paid Eversource an average of 19.88¢ per kWh in 2025 and its 984 full-service industrial accounts 16.30¢ per kWh; across all its customers the average was 23.06¢ per kWh. Businesses with a supplier paid Eversource 10.09¢ per kWh (commercial) and 7.38¢ per kWh¹ (industrial) for delivery only, plus their supplier's charge.

New Hampshire received $33.3 million¹⁰ in federal LIHEAP heating and energy assistance for fiscal 2026. The guide to help paying an electric bill and the New Hampshire page cover assistance and the state picture.
