Why Massachusetts pays what it pays

It is easy to blame Massachusetts rates on the price of power. The larger share of the story is the delivery side. The state runs an ambitious set of programmes through the electric bill: energy efficiency through Mass Save, solar incentive recovery, storm and grid resilience investment, and low-income discount subsidies. Each is a line item on delivery, and delivery has been growing faster than supply for several years.

The supply side still matters in winter. Massachusetts sits at the end of the same constrained pipeline network as the rest of New England, and the region's marginal generator is usually gas. Basic-service supply prices are procured twice a year, so the winter rate and the summer rate can differ by a wide margin even when nothing about the underlying market has changed.

The state is also a large offshore-wind buyer. Those contracts are long-dated and their costs enter rates gradually, which affects the trajectory more than the current figure.

Where Massachusetts power comes from

Massachusetts generated 23 TWh in 2025, the 41th largest output of any state. Natural gas supplied 77.3% of it, enough that the price of that fuel largely sets the price of electricity here. Renewables accounted for 15.8%, against 23.8% nationally, which ranks Massachusetts #28 of 51.

Net generation by fuel, 2025
  • Natural gas 18 TWh
  • Solar 3 TWh
  • Hydroelectric 827 GWh
  • Petroleum 402 GWh
  • Wind 210 GWh
  • Other 1 TWh

What Massachusetts households actually pay

Average monthly bill $183 +18.0% vs the U.S. average of $155

Massachusetts looks cheaper on paper than it is in practice. It has the 47th cheapest rate in the country but only the 5th highest bill from the bottom, because households there use 603 kWh a month against a national average of 871. See how every state compares on bills.

Heating in Massachusetts: gas, heat pump or resistance

Residential natural gas in Massachusetts averaged $21.90 per thousand cubic feet in 2024, about $2.11 per therm, against a national average of $14.50. Put on the same scale as the state's electricity rate, the cost of delivering one million BTU of heat works out as follows.

Gas furnace $23.47 at 90% efficiency
Heat pump $28.15 at a seasonal COP of 3
Electric resistance $84.46 baseboard, wall or electric furnace

In Massachusetts, gas remains cheaper to run than a heat pump by about $4.68 per million BTU at these assumptions, roughly $281 over a 60 million BTU season. A heat pump can still be the better purchase once cooling, equipment age and incentives are counted, but not on heating cost alone.

What each Massachusetts utility charges

The statewide average hides a wide spread. Across the 26 Massachusetts utilities reporting to the EIA, rates run from 13.39¢ at Town of Hudson to 40.08¢ at Fitchburg Gas & Elec Light Co . Together they serve 1.3 million residential customers.

Who sells electricity in Massachusetts

Eversource and National Grid serve most of the state, with Unitil in a smaller territory. Massachusetts has full retail choice and the most developed municipal aggregation market in the United States, with several hundred communities buying supply on behalf of residents.

The competitive residential supplier market has been a persistent problem for the state's Attorney General, whose office has repeatedly found that individual residential customers who switched paid more in aggregate than they would have on basic service. Aggregation, negotiated by a municipality at scale, has generally performed better than door-to-door individual switching.

Massachusetts sits in New England. Six states sharing one constrained gas pipeline network, which sets the winter price for all of them. Read the regional analysis.

What you can actually do about it

Read the delivery section of a Massachusetts bill before you shop for supply. If most of the charge is delivery, a supply switch cannot move the total much.

Mass Save's no-cost home energy assessment is the highest-leverage first step for most households. Its insulation and air sealing incentives are unusually generous, funded by the same bill charge you are already paying.

Closest states by price

These jurisdictions charge within a fraction of a cent of Massachusetts, which is useful if you are comparing a move or a multi-state operating cost.

Massachusetts electricity rates: common questions

Your own bill depends on the size of your home, your heating and cooling equipment and your rate schedule.

Why is the Massachusetts bill ranking different from its rate ranking?

A bill is the rate multiplied by usage, and usage varies between states more than price does. Massachusetts ranks #5 of 51 on price but 5th on the actual bill, because households there use about 603 kWh a month against a national average of 871. Climate and heating fuel drive most of that difference.

Have electricity rates in Massachusetts gone up?
