About Eversource in New Hampshire

Eversource Energy is a publicly traded utility holding company (NYSE: ES) with operations in Connecticut, Massachusetts and New Hampshire. The NH operating subsidiary was chartered in 1926 as Public Service Company of New Hampshire (PSNH) and is still legally referred to as PSNH d/b/a Eversource Energy. The brand consolidation took place in 2015 following the 2012 merger of Northeast Utilities and NSTAR.

PSNH/Eversource owns and operates the wires, substations and meters that move electricity to roughly 211 communities in central and southern New Hampshire, Manchester, Nashua, Portsmouth, Concord (north of the Capital district), Salem, Derry, Keene, Lebanon and most of the I-93 and I-89 corridors. Liberty Utilities serves the Salem-area and Seacoast pockets, and Unitil serves the Capital-Concord and Seacoast/Hampton clusters. New Hampshire Electric Co-op (NHEC) covers most of the rural north.

Since 2003, Eversource has been a wires-only utility in NH: it no longer owns generation. The power on your bill comes from a default-service auction held twice a year (rate resets 1 February and 1 August), a Community Power program, or a competitive supplier you chose.

PSNH default service rate, Feb-Jul 2026

In December 2025, Eversource filed new default service rates with the NH PUC. The small-customer rate (residential and small business) replaces the previous six-month rate that ran from August 2025.

What it means for you

The default service charge is only the supply half of your bill. Delivery (poles, wires, public-benefits adders) is a separate line item set by the PUC. As of May 2025, about 45% of Eversource NH residential customers no longer take default service, they buy supply from a Community Power program or a competitive supplier. Compare your last 12 months on the Eversource portal before locking in a contract.

Frequently asked questions

Is PSNH the same company as Eversource?
Yes. The legal entity is still Public Service Company of New Hampshire, doing business as Eversource Energy since the 2015 brand consolidation. Old paperwork that says PSNH is still valid.
Can I shop for a cheaper electricity supplier in NH?
Yes. New Hampshire deregulated retail electric supply in 1996. You can stay on Eversource Default Service, join a municipal Community Power program (Lebanon, Portsmouth, Nashua, Hanover, Exeter and 50+ others) or pick a licensed competitive supplier. Delivery stays with Eversource either way.
What is the Eversource NH default service rate right now?
For small (residential) customers, the all-in default service rate is $0.11303/kWh from February 1, 2026 through July 31, 2026. Large customers are billed at a different rate that resets monthly. The next small-customer reset is August 1, 2026.
Who do I call for a downed power line or outage?
Call Eversource 24/7 at 1-800-662-7764. If a wire is on the ground or anyone is hurt, dial 911 first, then Eversource. Do not approach a downed line; assume it is energized.
Does Eversource deliver natural gas in NH?
No. In New Hampshire, Eversource delivers electricity only. Natural gas distribution is handled by Liberty Utilities (most of the state) and Unitil Northern Utilities (Seacoast).
How do I start service when I move in?
Call 1-800-662-7764 or use the online start-service form at least 2 business days before move-in. You will need your name, the service address (apt, street, ZIP), move-in date, and a government-issued ID. A deposit may apply for non-homeowner accounts without a prior payment history.
