Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Homes in MA counts only the customers in this state. Price and bill cover the utility's whole territory and bundled customers only. Delivery only means the utility carries power but does not sell it.
Who owns Massachusetts's electric companies
| Type | Utilities | Homes in MA | Share of homes |
|---|---|---|---|
| Investor-owned utility | 4 | 2,546,096 | 90.8% |
| Municipal utility | 16 | 258,300 | 9.2% |
Each type is run differently. An investor-owned company answers to shareholders and a state commission. A municipal utility answers to a city. A cooperative answers to its members. That is why the same state can have very different prices and service from one address to the next.
What Massachusetts utilities charge, by type
| Type | Utilities with a price | Average cents per kWh |
|---|---|---|

| Municipal utility | 16 | 16.88 |
Source: U.S. Energy Information Administration, Form EIA-861 (final 2025 data). Customer-weighted average of the prices utilities report for bundled residential service. It leaves out delivery-only customers and retail providers.
Outside the investor-owned companies, the largest municipal utility is City of Taunton (34,952 homes).
Price differences between types come from costs, customer density and the way each type is financed, so a lower average does not decide which is better for your home.
