Maryland Electricity

What Maryland's Electricity Data Tells Us

Residential customers in Maryland pay 17.86¢/kWh in 2024, spread across 2.5M metered households, placing the state 8.4% above the national residential average of 16.48¢/kWh. Commercial rates sit at 12.96¢/kWh while industrial buyers pay 10.01¢/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 27.3M MWh on roughly $4880.1M in utility revenue, a useful yardstick for sizing local demand against the grid mix that serves it.

The generation mix is led by nuclear at 40.0% of in-state production, with natural gas providing 37.7% and solar supplying 6.8%. Renewable fuels, solar, wind, hydro, geothermal, and biomass, collectively account for 14.1% of Maryland's electricity output, a figure that matters because each renewable megawatt-hour displaces fuel costs that otherwise flow through to retail bills. Expansion headroom remains: cost curves for wind and solar have fallen faster than fossil alternatives for most of the last decade.

Looking back across EIA records, residential prices in Maryland moved from 14.23¢/kWh in 2016 to 17.86¢/kWh in 2024, a 25.5% shift over that window. Comparable-priced neighbors include Pennsylvania, District of Columbia, Wisconsin, 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.
