Massachusetts Electricity

What Massachusetts's Electricity Data Tells Us

Residential customers in Massachusetts pay 29.35¢/kWh in 2024, spread across 2.9M metered households, placing the state 78.1% above the national residential average of 16.48¢/kWh. Commercial rates sit at 20.90¢/kWh while industrial buyers pay 18.19¢/kWh, reflecting the cost differentials that come from voltage level, load factor, and contract length across EIA Form-861 survey respondents. Annual residential sales total 20.0M MWh on roughly $5867.8M in utility revenue, a useful yardstick for sizing local demand against the grid mix that serves it.

The generation mix is led by natural gas at 62.8% of in-state production, with solar providing 24.0% and other supplying 3.6%. Renewable fuels, solar, wind, hydro, geothermal, and biomass, collectively account for 31.1% of Massachusetts's electricity output, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. A portfolio this clean typically carries lower marginal generation costs once capacity is built, though transmission upgrades can offset part of the saving.

Looking back across EIA records, residential prices in Massachusetts moved from 19.00¢/kWh in 2016 to 29.35¢/kWh in 2024, a 54.5% shift over that window. Comparable-priced neighbors include Connecticut, Rhode Island, California, which gives a peer set for sanity-checking local quotes. For anyone negotiating a supplier contract, weighing an energy-efficiency upgrade, or modeling a household budget, the combination of current rate, multi-year trend, and generation mix offers a sturdier footing than any single data point on its own.
