A note on New Hampshire's market: Residential retail choice is available statewide and a large and growing share of households are served by municipal Community Power aggregations.
What the Average Electric Bill in New Hampshire Actually Is
The average New Hampshire household pays about $169.17 a month for electricity, roughly 6 percent above the national average of $159.14. But the two numbers underneath tell a far more interesting story than the total does. The state's rate is 27.33 cents per kilowatt-hour as of May 2026 — about 48 percent above the national average of 18.44 cents — while consumption averages just 619 kilowatt-hours a month, roughly 28 percent below the national 863.
New Hampshire households are, by national standards, extremely frugal users of electricity. They simply pay a great deal for each unit. That combination has consequences that run through everything else on this page: efficiency measures return more per kilowatt-hour saved here than in almost any state, and the remaining consumption is already lean enough that finding further reductions is harder than the advice columns suggest.
The critical caveat is that this bill is not the household's energy cost. New Hampshire heats overwhelmingly with fuel oil, propane, and wood, with natural gas available only in limited parts of the state. A typical household's largest annual energy expense arrives by delivery truck and never touches the electric meter. A New Hampshire family looking at a $169 electric bill and concluding that energy is manageable is looking at perhaps half the picture, or less, in a cold winter. Air conditioning, meanwhile, is modest and short-lived, so unlike most of the country the summer is not the peak. Feed your own numbers into the electricity bill calculator and treat the result as one line in a larger household energy budget.
Why New Hampshire Pays 27.33 Cents per Kilowatt-Hour
New Hampshire sits inside the New England regional grid, and the region's cost problem is structural rather than a matter of local mismanagement.
Generation depends heavily on natural gas, and the pipelines are constrained. New England has limited pipeline capacity into the region, and on the coldest days that capacity is prioritised for heating customers over power generators. Generators then bid at much higher prices, or burn oil, and because wholesale electricity markets clear at the price of the most expensive unit needed, the entire region's power price rises with them. A handful of very cold days can shape a season's costs.
Transmission is expensive. New England has invested heavily in transmission over the past two decades, and those costs are allocated across the region and recovered from customers. The transmission component of a New Hampshire bill is a larger share of the total than most customers realise.
Delivery is expensive. New Hampshire is heavily forested, hilly, and dispersed. Overhead lines through mature tree canopy in a state with ice storms, nor'easters, and heavy wet snow require constant vegetation management and frequent restoration work. Line-miles per customer are high outside the southern tier.
The market is unbundled. New Hampshire has residential retail choice, so your bill separates the supply charge (the cost of the electricity itself, from whichever supplier you use) from the delivery charge (what you pay the wires company to move it to you, regardless of who generated it). Only the supply half is competitive. Delivery is set by the regulator and is the same whoever supplies you — a fact that a great deal of marketing in this state depends on you not knowing. The supply versus delivery guide is worth reading before evaluating any offer.
Why New Hampshire Households Use Only 619 kWh a Month
619 kilowatt-hours a month is a low figure by any standard, and the reasons are almost entirely about what electricity is not being asked to do here.
- Heating is not electric. Fuel oil, propane, and wood dominate, with natural gas in limited service areas. The single largest energy load in a New Hampshire home is bought by the gallon or the cord, not the kilowatt-hour. This one fact accounts for most of the gap between New Hampshire and states with electric heat.
- The cooling season is short and mild. Central air conditioning is far from universal, window units and mini-splits are common where cooling exists at all, and the number of days demanding continuous cooling is small. Nights cool off reliably.
- Rates this high change behaviour. When electricity costs nearly half again the national average, households notice. Over time, high prices push out resistance water heaters, incandescent lighting, and electric dryers faster than in cheap-power states.
- Efficiency programs have a long history in the region. New England utilities have run ratepayer-funded efficiency programs for decades, and the cumulative effect on the housing stock is real.
The wrinkle worth flagging is that this is changing. Cold-climate heat pumps and electric vehicles both move energy consumption from a delivered fuel or a gas pump onto the electric meter. A household that installs heat pumps will see its electric bill rise sharply while its total energy cost potentially falls — a distinction that causes a lot of confusion and a lot of misplaced regret. If you are considering that switch, compare annual dollars across all fuels, not electric bill to electric bill.
Shopping for Supply: What Works and What Is a Trap
New Hampshire has statewide residential retail choice, so the supply half of your bill is genuinely contestable. It also means an active competitive marketing industry whose offers range from good to predatory. What to understand before signing:
- The default is not nothing. If you choose no supplier, your utility provides default service at a rate set periodically through regulated procurement. Beating that benchmark is not automatic, and competitive offers are frequently compared against a stale default rate rather than the current one.
- Community Power is now the other default. A large and growing share of New Hampshire households are served by municipal Community Power aggregations, in which a town or city procures supply on behalf of its residents. Enrolment is automatic in a participating municipality unless you opt out, and you keep the right to leave or to choose a competitive supplier. These programs typically publish rates and terms openly and do not charge early termination fees — a materially different proposition from a door-to-door contract.
- Teaser rates expire, and the rollover is the point. The standard trap is a low introductory rate on a short fixed term that converts automatically to a variable rate. That variable rate is where the supplier makes its money, and it can run far above default service. Diary the end date the day you sign.
- Read for minimum-usage fees and bill credits. Some plans advertise a low per-kWh price but add a monthly fee unless you exceed a usage threshold. In a state averaging 619 kWh a month, a plan built around a 1,000 kWh benchmark is designed to be missed. Bill-credit plans have the same shape: the headline rate only holds at a usage level most New Hampshire households never reach.
- Early termination fees turn a bad contract into an expensive one. Check the number before signing.
- Switching supply never changes your delivery charge, your wires company, your reliability, or who restores your power. Anyone implying otherwise is misrepresenting the product.
Shopping supply here can save money, but the saving is a percentage of roughly half your bill, and it evaporates the moment a contract rolls to variable.
The Utilities Serving New Hampshire and How They Differ
Whoever supplies your electricity, one of four distribution companies owns the wires to your house, and that determines your delivery rate, your reliability, and your restoration times.
Eversource Energy is the largest, serving most of the southern tier and a broad share of the state's customers. As the biggest distribution company it spreads fixed costs across the most meters, but it also carries an extensive rural overhead network with heavy tree exposure.
Liberty Utilities serves a smaller electric territory and is also a natural gas distributor in parts of the state, one of the few places in New Hampshire where a household can choose gas heat at all.
Unitil serves a compact territory including the Seacoast area and Concord. It is a small company with a concentrated, relatively urban service area, which produces a different cost structure from a sprawling rural network.
New Hampshire Electric Cooperative is member-owned, governed by a board its members elect rather than being structured to earn a shareholder return, and serves a large, rural, heavily wooded territory across much of the state's centre and north. Sparse rural distribution is expensive to build and maintain, and the co-op's cost structure reflects that geography.
The structural point is that delivery charges are not comparable across these four, and neither are the outage statistics. A household in Unitil's Seacoast territory and a household on a co-op line in Coos County face very different physical systems. When comparing bills with someone in another town, check the distribution utility before concluding anything about who is using electricity more carefully.
Heat Pumps, Electrification, and the Bill That Is About to Change
New Hampshire's electricity profile — very low usage, very high price — is the product of a household energy system built around delivered fuels. That system is now shifting, and the arithmetic is genuinely non-obvious.
Cold-climate air-source heat pumps work in New Hampshire winters, delivering more heat energy than the electrical energy they consume even at low outdoor temperatures. Against fuel oil or propane at typical prices, that efficiency advantage can more than offset a 27.33-cent electricity rate. But the effect on the bill is dramatic: a household that heats with heat pumps might double or triple its winter electric consumption while cutting or eliminating its fuel deliveries. The electric bill goes up. The total energy bill may well go down.
Two consequences follow. First, never evaluate an electrification decision from the electric bill alone — the comparison is annual dollars across every fuel the household buys, before and after. Second, once heating is on the meter, your supply arrangement matters far more than it did, because you have moved a large load onto the highest unit price in the household. A contract worth a few dollars a month at 619 kWh is worth considerably more at 1,500.
The same logic applies to electric vehicles, which shift fuel spending onto the electric meter. In a state with prices this high, the household that thinks in total energy dollars rather than individual bills comes out ahead. The appliance energy cost calculator will price specific loads at New Hampshire's rate, which is the fastest way to see how quickly high per-kWh prices compound.
Frequently asked questions
Why is New Hampshire's electricity rate so high?
The state sits in the New England regional market, where several costs stack. Natural gas sets the wholesale power price much of the time, and pipeline capacity into the region is constrained, so on cold days gas is scarce and expensive for generators and the whole region's price rises. Transmission investment across New England is substantial and recovered from customers. Distribution is costly in a forested, hilly, dispersed state with severe winter weather. At 27.33 cents per kWh, the rate is about 48 percent above the national average of 18.44 cents, and very little of that gap is within any one utility's control.
Should I switch electricity suppliers in New Hampshire?
Possibly, but only after comparing against the right benchmark. Your alternative is either your utility's current default service rate or, in many towns, a municipal Community Power rate — not the stale figure a marketer quotes. Check the contract term, whether it converts to a variable rate at expiry, whether there is an early termination fee, and whether the advertised price depends on a minimum monthly usage. In a state averaging 619 kWh a month, plans built around a 1,000 kWh benchmark are designed so that most households miss the threshold and pay more.
What is Community Power in New Hampshire?
It is municipal aggregation: a town or city procures electricity supply on behalf of its residents and businesses, using collective buying power in place of individual contracts. A large and growing share of New Hampshire households are now served this way. Residents of a participating municipality are enrolled automatically unless they opt out, and you can leave at any time or choose a competitive supplier instead. Programs generally publish their rates and terms openly and do not impose early termination fees, which makes them a considerably more transparent option than most door-to-door supply offers.
Why is my New Hampshire electric usage so low compared to other states?
Because your house probably does not heat or cool with electricity. New Hampshire heats mainly with fuel oil, propane, and wood, so the household's largest energy load never reaches the electric meter, and the cooling season is short enough that air conditioning adds little. The result is average consumption of 619 kWh a month against a national 863. The important implication is that your electric bill is not your energy bill. Add your fuel deliveries to it before deciding whether your household energy spending is high or low.
Will a heat pump raise my electric bill in New Hampshire?
Yes, and that alone does not mean it was a bad decision. A cold-climate heat pump moves heating energy from delivered fuel onto the electric meter, so winter electricity consumption rises substantially while oil or propane deliveries fall or stop. Because heat pumps deliver more heat than the electrical energy they consume, the total annual energy cost can fall even at 27.33 cents per kWh. Judge the decision on combined annual spending across all fuels, before and after. And once heating is on the meter, your supply contract and rate structure matter far more than they did.
