Eversource electricity rates in Connecticut, Massachusetts and New Hampshire
Eversource is three separately regulated utilities, and in 2025 their full-service residential customers paid averages from 21.49¢ per kWh in Massachusetts to 28.88¢ per kWh1 in Connecticut. Those figures describe only homes that buy supply from Eversource, which in Massachusetts is a minority of the homes on its wires.
Three utilities behind one name
Eversource Energy owns three distribution utilities, each with its own tariffs and its own regulator: The Connecticut Light and Power Company, NSTAR Electric Company in Massachusetts and Public Service Company of New Hampshire. EIA reports each one separately, under those legal names, and together they serve 2.9 million residential accounts in 2025. All three report ISO New England1 as their regional grid operator. Each has its own page here: Eversource in Connecticut, Eversource in Massachusetts and Eversource in New Hampshire.
Eversource prices per kWh in each state
The figures below are average revenue per kWh: what full-service residential customers paid in total, fixed charges and riders included, divided by the kWh they used. They are not tariff rates, and they cover only customers who buy their supply from Eversource (standard service in Connecticut, basic service in Massachusetts, energy service in New Hampshire).

| Utility | average residential price (bundled customers) |
|---|---|
| Eversource (MA) | 21.49¢ |
| Eversource (NH) | 24.17¢ |
| Eversource (CT) | 28.88¢ |
In 2025, Connecticut Light and Power customers paid an average of 28.88¢ per kWh, 10th highest of 177 utilities with 100,000 or more residential customers and 62.4% above the national average for investor-owned utilities. New Hampshire followed at 24.17¢ per kWh (18th highest of 177), Massachusetts at 21.49¢ per kWh (28th highest of 177). Weighted by what each sold, Eversource's full-service customers averaged 27.00¢ per kWh1.
EIA's monthly survey gives a more recent view. Over the last 12 months (September 2025 to August 2026, with 2026 months preliminary), the averages were 26.89¢ per kWh in Connecticut, 26.17¢ per kWh in New Hampshire and 19.73¢ per kWh2 in Massachusetts.
In Massachusetts, the published price covers a minority of homes
All three states let households buy supply from a competitive supplier or, where one exists, a community aggregation program while Eversource keeps delivering the power. How many do so differs sharply. In 2025, 75.9% of residential customers on NSTAR Electric's wires bought supply elsewhere, against 43.2% in New Hampshire and 16.6% in Connecticut. Of 1,274,856 residential accounts on the Massachusetts wires, only 306,795 were full-service customers, the group behind the 21.49¢ per kWh average. In Connecticut the full-service group was 995,130 of 1,193,5811.
For homes on a supplier, Eversource bills delivery only. In 2025 that delivery-only revenue averaged 20.06¢ per kWh in Massachusetts, 18.65¢ per kWh in Connecticut and 14.20¢ per kWh1 in New Hampshire; the supplier's charge comes on top, at a price EIA does not report by utility. Delivery-only averages cover a different group of customers and a different part of the bill, so they cannot be compared directly with the full-service prices above.

Rate increases and decreases since 2024
From 2024 to 2025, the full-service average fell 28.2% in Massachusetts, from 29.91¢ per kWh3 to 21.49¢ per kWh, and rose 6.7% in New Hampshire and 1.3%1 in Connecticut. EIA's figures do not say why the Massachusetts average fell; it is a reported average for the smaller full-service group, and the Eversource Massachusetts page has the detail.
Delivery-only averages changed too. Between 2024 and 2025 they went from 16.27¢ per kWh to 20.06¢ per kWh in Massachusetts (+23.3%), from 16.26¢ per kWh to 18.65¢ per kWh in Connecticut (+14.7%) and from 13.12¢ per kWh3 to 14.20¢ per kWh in New Hampshire (+8.2%1).
For 2026, only EIA's monthly survey is available so far. In August 20264, the latest preliminary month, Connecticut's full-service average was 23.94¢ per kWh, −22.6% against August 2025. New Hampshire's was 27.24¢ per kWh (+10.0%) and Massachusetts's 20.85¢ per kWh (+6.1%2). In Connecticut, the Public Utilities Regulatory Authority (PURA) conditionally approved lower rates for Eversource from May 1, 2026 through April 30, 2027, and said lower public benefits charges, mainly the costs of the nuclear power contracts with Millstone and Seabrook, drove the decrease.

Bills: price times use, and three different peaks
In 2025, Connecticut combined the highest average price of the three with the most use per home. A full-service home there used 677 kWh a month and paid $195.35, +4.4% on 2024. New Hampshire homes used 620 kWh and paid $149.82 (+10.0%); Massachusetts homes used 474 kWh and paid $101.86 (−25.7%1).

| Utility | average monthly residential bill |
|---|---|
| Eversource (MA) | $101.86 |

The month of highest use is not the same in each state. Over the last 12 months (September 2025 to August 2026, preliminary), New Hampshire use peaked in January 2026 at 796 kWh per home, with an average bill of $202.27, and Massachusetts in February 2026 at 618 kWh. Connecticut's peak came in summer: July 2026, at 887 kWh and $209.24, yet Connecticut's largest average bill of the 12 months came in February 2026, at $243.212, on less electricity.
Solar, time-of-use and meters
Net-metered rooftop solar is more widespread on the Connecticut and Massachusetts systems than in New Hampshire. In EIA's 2025 data, Connecticut Light and Power reported 76.2 net-metered residential installations per 1,000 residential customers (90,904 in all), NSTAR Electric 70.2 (89,475) and Public Service Company of New Hampshire 40.5 (18,7745).
Time-varying pricing is rare: 611 residential customers in Connecticut (0.1% of those on the wires) and 97 in New Hampshire were enrolled in 2025. The share of residential meters that were advanced (AMI) was 0.0% in Connecticut, 0.0% in Massachusetts and 0.0%5 in New Hampshire in EIA's 2025 meter data.
Outages
Counting major storms, a Connecticut Light and Power customer was without power for 217 minutes on average in 2025, more than the Connecticut average of 211 minutes. In New Hampshire the figure was 161 minutes, fewer than the New Hampshire average of 231 minutes, and in Massachusetts 113 minutes, fewer than the Massachusetts average of 122 minutes. Without major event days the three were closer: 85 minutes, 83 minutes and 66 minutes6.

Questions and answers
What is Eversource's rate per kWh?
There is no single Eversource rate: each state's utility has its own tariffs. EIA's average revenue per kWh, which includes fixed charges and riders, was 28.88¢ per kWh in Connecticut, 24.17¢ per kWh in New Hampshire and 21.49¢ per kWh1 in Massachusetts for full-service residential customers in 2025. Over the last 12 months (September 2025 to August 2026, 2026 months preliminary) the averages were 26.89¢ per kWh, 26.17¢ per kWh and 19.73¢ per kWh2.
Did Eversource rates go up or down in 2026?
It depends on the state. In August 20264, the latest preliminary month, the full-service average was −22.6% against August 2025 in Connecticut, +10.0% in New Hampshire and +6.1%2 in Massachusetts.
What is the average Eversource electric bill?
In 2025, EIA's figures give an average monthly residential bill of $195.35 in Connecticut, $149.82 in New Hampshire and $101.86 in Massachusetts, for full-service customers. Use per home explains much of the gap: 677 kWh, 620 kWh and 474 kWh1 a month.
