Priciest vs cheapest
Massachusetts has no single electricity rate — your utility sets it, and we track 45 of them. Current 2026 all-in residential rates run from about $0.13/kWh at South Hadley Electric Light Department to $0.4814/kWh at Unitil, so the priciest utility costs roughly 3.7× the cheapest. Most residents are served by Eversource ($0.3736/kWh) or National Grid ($0.4178/kWh). Enter your town or ZIP below for the rate that actually applies to you.

Every rate is the all-in bundled figure from that utility's own tariff — not a state average.
All 45 utilities, sorted cheapest to most expensive. Each figure is the all-in bundled residential rate (delivery + supply + customer charge) as it lands on a typical bill, with the effective date it took hold. Municipal light plants cluster at the low end; the investor-owned utilities sit at the top.

Source: each utility's own published residential tariff. Effective dates reflect the last confirmed rate change on file; some smaller municipal plants publish annually, so an older date is not a stale figure.
Two things determine your rate: which kind of utility serves your town, and how that utility builds its bill. Both vary enormously across Massachusetts.
About 41 Massachusetts towns run their own municipal light plant(MLP) — a town-owned, non-profit utility that buys power at cost and answers to residents. The rest are served by investor-owned utilities (Eversource, National Grid, Unitil) that must earn a regulated return for shareholders and carry much larger delivery-charge structures. That structural split is the single biggest reason a customer in an MLP town can pay roughly 3.7× less than a neighbor 20 miles away.
Every bill has three parts. Supply is the electricity itself. Delivery is what the utility charges to move it over the wires, plus policy surcharges. The customer chargeis a fixed monthly fee. The all-in rate on this page adds all three together, because that combined number — not the supply-only “price to compare” — is what actually determines your bill.
Eversource, National Grid, and Unitil serve most of the state and carry the highest rates — driven by delivery charges and New England supply costs.
Town-owned, non-profit, and typically the cheapest electricity in Massachusetts. Each sets its own rate locally.
Eversource resets its supply rate twice a year; National Grid once. Municipal plants set their own calendars, so effective dates vary across the table.
Eversource updates its Basic Service supply rate twice a year, so its all-in bundled rate can move on August 1, 2026. We don't publish a projected number before the filing is final — the Eversource figure in the table above updates from the utility's own tariff once the new rate takes effect. Check back after August 1 for the confirmed rate, or use the lookup to see the current figure any time.
Structurally, Massachusetts is a high-cost electricity region — but only for the investor-owned utilities most residents are on. The reasons are the same ones that keep New England near the top of the national tables year after year.
New England generates roughly half its power from natural gas but has limited winter pipeline capacity, so cold snaps spike wholesale supply costs.
ISO New England’s forward capacity auctions and grid-reliability requirements flow through to delivery charges for every investor-owned-utility customer.
Grid modernization and offshore-wind contract costs are recovered through delivery charges that climb regardless of what supply prices do.
We deliberately don't reduce Massachusetts to one “state average” number — it would misrepresent both the municipal-light-plant town paying near 13¢/kWh and the Unitil customer paying over 48¢/kWh. For how these rates have moved over time and where they're headed, see our Massachusetts electricity rate trends analysis.
The higher your utility's rate, the more each self-generated or avoided kilowatt-hour is worth. Your rate is the single biggest input to solar payback and heat-pump running-cost math — which is exactly why it has to be your utility's rate, not a state average.
Every kWh your panels produce offsets your full retail rate. An Eversource, National Grid, or Unitil customer offsets far more per kWh than a low-rate municipal customer, so the same system pays back faster on the investor-owned utilities. Run your own numbers on your exact rate:
See your solar savingsA heat pump's operating cost is its electricity use times your rate, so the switch from oil or propane pencils out differently in an MLP town than on Eversource. Massachusetts pairs high rates with Mass Save rebates for investor-owned-utility customers — see how that changes the math:

There is no useful single average. Massachusetts electricity rates are set per utility, and the spread across the 45 utilities we track is enormous — from about $0.13/kWh at South Hadley Electric Light Department to $0.4814/kWh at Unitil in 2026. Blending those into one “state average” would hide the fact that two towns 20 miles apart can differ by roughly 3.7×. The only rate that means anything is your own utility’s — look it up above.
