Why your address matters
Two kinds of utility, two sets of rules
In New Hampshire, the type of utility that serves your town decides whether you can shop your supply or not. There is no third option.
Investor-owned · IOU
Eversource, Liberty, Unitil
Private companies regulated by the NH Public Utilities Commission (PUC). They own the wires (delivery), set the auction-priced Default Service rate (default supply) and let you swap that supply line for a competitive offer.
- You can choose a competitive electricity supplier (residential retail choice since 2003).
- Your town may also run a Community Power aggregation you are enrolled in by default.
- Outage and gas-emergency response is run by the IOU, 24/7.
Roughly ~650K NH meters fall in IOU territory.
Municipal · MLP
13 town-owned utilities
The town owns the wires and the supply, and sets the rate through a local Electric Commission. Ashland, Wolfeboro and Woodsville are typical examples. Rates are often lower than the IOU side, but choice is off the table.
- No competitive supplier choice. Retail choice does not apply in MLP towns.
- Rates are usually 20 to 40 percent below the IOU equivalent, set at cost.
- Local outage response, local billing, local board you can vote for.
Roughly ~2% of NH meters are in MLP towns.
Save these
Every NH utility outage & gas line, one table
Always call your delivery utility for outages and gas emergencies, never your competitive supplier.

CallMePower explains
What your NH utility actually charges for
Every NH electric bill has two halves. Your utility owns one, the market owns the other.
Supply (you can shop this)
The cost of the kilowatt-hours you actually use, billed in ¢/kWh.
- • Default Service (Energy Service on Eversource) from your IOU if you do nothing. Reset every 6 months.
- • Competitive supplier if you shop. Same kWh, different price line.
- • Community Power if your town has joined the program. Opt-out anytime.
Delivery (utility-only)
The cost of moving electricity through the utility's wires and meters. Cannot be shopped.
- • Customer charge, a fixed monthly fee. Paid even if you use zero kWh.
- • Distribution, the ¢/kWh wires charge.
- • Transmission, stranded-cost, energy-efficiency, system-benefits, small per-kWh adders set by the NH PUC.
Quick answers
Common questions households ask before calling.
Look at the top of your last bill. If you do not have one yet, the answer is set by your town. Eversource (PSNH) covers Concord, Manchester, Nashua, Salem and most of southern and central NH. Liberty Utilities covers the Lakes Region for electric, and Greater Nashua / Manchester for gas (see the Tilton office). Unitil covers the Seacoast and Capital area for electric, and Concord / Laconia / Tilton for gas (see the Kensington office). Thirteen NH towns run their own Municipal Electric Department, the three indexed here are Ashland, Wolfeboro and Woodsville.
An Investor-Owned Utility (IOU) is a private regulated company, like Eversource, Liberty and Unitil. A Municipal Light Plant (MLP) is owned by the town itself. The practical consequence: in IOU territory you can pick a competitive electricity supplier; in MLP territory you cannot, the town supplies and bills you directly at rates it sets locally.
No. The delivery utility is set by where you live, you cannot change it. You can, however, switch the supply portion of your bill to a competitive supplier (in IOU territory), or enroll in a Community Power program if your town offers one.
Always your delivery utility, 24/7. Eversource NH: 1-800-662-7764. Liberty Utilities: 1-855-849-9455. Unitil: 1-888-901-5711. Ashland: (603) 968-3083. Wolfeboro: (603) 569-6975. Woodsville: (603) 747-2442.
Leave the building first, then call the gas emergency line from outside. Liberty NH gas: 1-855-849-9455. Unitil gas: 1-866-900-4115. Eversource does not deliver gas in New Hampshire. Service at the meter is free.
Investor-owned utilities are regulated by the New Hampshire Public Utilities Commission (PUC), which approves delivery rates and sets the Default Service auction rules. Municipal Electric Departments are not under PUC jurisdiction for rate-setting, they answer to their local Electric Commission and the town meeting.
