Eversource's standard electric price changes in early 2027 in all three of its states: January 1 in Connecticut and February 1 in Massachusetts and New Hampshire. When we checked on October 12, 2026, none of the new prices had been announced yet.

This post sticks to what's known: today's prices, the dates they change, and when the new ones usually come out. No one can tell you the new price before it's set, and I won't guess. I'll update this post as each new price is announced. The newest numbers always show first on our pages for Eversource Connecticut Standard Service, Eversource Eastern Massachusetts Basic Service, Eversource Western Massachusetts Basic Service and Eversource New Hampshire Default Service.

Same company, three names for the price

If you never picked an electric supplier, you pay Eversource's own price for the electricity itself. Each state calls it something different:

  • Connecticut: Standard Service
  • Massachusetts: Basic Service
  • New Hampshire: Default Service

It covers only the supply part of your bill. Delivery, for the wires and poles, is separate, and you pay it to Eversource whoever sells you the power.

Today's prices and when they change

Checked October 12, 2026:

| State | Eversource's price today | Runs through | Next change | | --- | --- | --- | --- | | Connecticut | 11.577¢ per kWh | December 31, 2026 | January 1, 2027 | | Massachusetts, eastern | 17.323¢ per kWh | January 31, 2027 | February 1, 2027 | | Massachusetts, western | 15.934¢ per kWh | January 31, 2027 | February 1, 2027 | | New Hampshire | 14.009¢ per kWh | January 31, 2027 | February 1, 2027 |

A kWh, or kilowatt-hour, is one unit of electricity. Your bill shows how many you used.

Connecticut: Standard Service changes January 1

Connecticut's Standard Service changes twice a year, on January 1 and July 1. The state's utility regulator, the Public Utilities Regulatory Authority (PURA), approves the new price ahead of time. For January 2024, PURA announced the new prices on November 21, 2023.

Here is how Eversource's Connecticut price has moved, from the state's EnergizeCT rate board and PURA:

| Period | Eversource Standard Service | | --- | --- | | January to June 2023 | 24.172¢ | | July to December 2023 | 13.820¢ | | January to June 2024 | 14.714¢ | | July to December 2024 | 8.995¢ | | January to June 2025 | 11.190¢ | | July to December 2025 | 9.748¢ | | January to June 2026 | 12.641¢ | | July to December 2026 | 11.577¢ |

The January price has been higher than the July before it in each of the last three years. That's a pattern, not a promise.

What offers looked like on October 12, 2026: EnergizeCT listed 17 fixed offers for Eversource customers, from 13.55¢ to 16.89¢. None was below Eversource's 11.577¢. See Connecticut price changes for the January price once it's posted.

Massachusetts: Basic Service changes February 1

In Massachusetts, Eversource's Basic Service changes on February 1 and August 1. Eastern and western Massachusetts have different prices.

The state's Energy Switch Massachusetts site lists the next period, February through July 2027, with no price yet. The price appears there once Eversource files it. It will show on our pages too, and on Massachusetts price changes.

What offers looked like on October 12, 2026:

  • Eastern Massachusetts: 42 fixed offers. 27 were below Eversource's 17.323¢.
  • Western Massachusetts: 28 fixed offers. 3 were below Eversource's 15.934¢.

Many Massachusetts towns also run their own electricity programs. If your bill shows your town's program, that's your price now, not Basic Service.

New Hampshire: Default Service changes February 1

Eversource's New Hampshire Default Service also runs in six-month periods, changing February 1 and August 1. Today's price, 14.009¢, runs from August 2026 through January 2027. The New Hampshire Public Utilities Commission's rate page and the Department of Energy's supplier list show the new price once it's set. Watch New Hampshire price changes.

What offers looked like on October 12, 2026: the state's list had 31 plans for Eversource customers. 6 of the 28 fixed plans were below 14.009¢.

Should I lock in a price before the change?

Only if the numbers work. Before you sign:

  1. Compare with today's price, and wait for the new one if you can. Once the new price is announced, you can compare against the real number instead of a guess.
  2. Read the term and the fee to leave early. A fixed price that beats a high winter price may not beat the next one.
  3. Ignore "prices are going up" pressure. Until the new price is announced, a seller doesn't know it either.
