How MA customer choice works
From the meter to the supplier in 3 moves
Every Massachusetts bill has two halves: delivery (the wires, owned by your utility) and supply (the kilowatt-hours, where the market opens up). Here is how to navigate both.
Identify your utility
Look at the top of your bill or use your ZIP code. In MA the two big investor-owned utilities are Eversource and National Grid; the rest are town-run Municipal Light Plants.
Pick your utility aboveCheck Basic Service
If you don't shop, your utility supplies you at the auction-set Basic Service rate. Residential rates reset on 1 January and 1 July. Always benchmark against the current rate, not last winter's.
See current MA pricesSwitch or aggregate
Sign up directly with a competitive supplier, or enroll in your town's municipal aggregation (Boston CCE, Cambridge CCE, and dozens more). Same wires, same meter, just a different supply line.
Compare suppliersThree reasons MA households shop their supply
Same electrons. Same gas. Same outage line. The only thing that changes is the supply price on one line of your bill.
Beat the Basic Service drift
Because Basic Service is locked in 6 months ahead, it lags the spot market. When wholesale prices fall, your utility keeps charging the old rate until the next reset. A competitive fixed plan can capture today's price.
Lock a rate for 12 to 36 months
A fixed competitive plan removes the 1 January / 1 July surprise. Useful if you remember the winter 2022 to 2023 Basic Service shock when residential rates briefly doubled past 17 ¢/kWh.
Go beyond the default green mix
Massachusetts mandates a baseline renewable share in every supply mix. Competitive 100% renewable plans (or green municipal aggregation tiers) push above that floor, often at parity with Basic Service.
Quick answers about MA energy
The most common questions households ask before they pick up the phone.
Your utility is set by your home address. The two large investor-owned electric utilities are Eversource (Greater Boston, South Shore, Cape and the Pioneer Valley / Berkshires) and National Grid (Central, MetroWest, North Shore, South Shore, Cape Cod and parts of the South Coast). If you live in one of the 41 Municipal Light Plant towns, your town runs its own utility.
Basic Service is the supply price your investor-owned utility charges if you do nothing. It is set at auction by the utility, regulated by the Department of Public Utilities, and resells the power at cost (no profit margin). For residential customers, the rate is reset on 1 January and 1 July. Commercial customers see new rates on a quarterly cycle.
Sometimes yes, sometimes no. Door-to-door pitches often quote a teaser rate that flips to a much higher variable rate after a few months. Always compare a fixed-rate offer to the current Basic Service rate, including any monthly fees, and check the termination clause. When the spread is real and the contract is clean, MA households can shave 10 to 25 percent off the supply line.
It is a town-run competitive supply program. Your city negotiates a bulk supply contract for everyone in town, and you are enrolled by default unless you opt out. Boston Community Choice Electricity, Cambridge CCE, Brookline, Somerville and dozens of other MA towns run aggregations. They usually offer a "standard" tier near Basic Service price and a "100% green" tier slightly above.
Always your delivery utility, never your competitive supplier. Eversource: 1-800-592-3000. National Grid: 1-800-465-1212. HG&E (Holyoke): (413) 536-9300. The outage and gas emergency lines stay the same whether or not you have switched suppliers.
