Maryland Electricity
As of May 2026, residential electricity in Maryland costs 21.77¢ per kWh (+14.6% vs May 2025). EIA publishes these figures monthly and this page follows them. Maryland's 2025 annual residential electricity rate is 19.48¢/kWh, 12.6% above the US average. Both figures point the same way: an above-average rate and only 14% of generation from renewables. The fuel-by-fuel and sector detail is below.

The verdict · 2025
Maryland's residential electricity runs 19.48¢/kWh - 12.6% above the 17.30¢/kWh national average, pricier than 74% of other states, with 14% of its power from renewables.

What Maryland's Electricity Data Tells Us
Residential customers in Maryland pay 19.48¢/kWh in 2025, across 2.5M metered households, placing the state 12.6% above the national residential average of 17.30¢/kWh. Commercial rates sit at 14.74¢/kWh while industrial buyers pay 12.50¢/kWh. These sector averages describe recorded revenue per kWh; this dataset alone does not establish why they differ. Annual residential sales total 28.0M MWh on roughly $5.5B in utility revenue. Sales and revenue are reported retail-series measures and should not be treated as a local load forecast.
Maryland prices its sectors in step: 14 of 51 residential against 11 industrial. A state this consistent is the exception rather than the rule, and it means the residential figure above is a fair proxy for how the whole grid is priced. No single fuel reaches half of Maryland's in-state generation. Natural gas leads at 40.8%, with nuclear at 37.6% close enough behind that the mix reads as a balance rather than a clear lead. It is the leading fuel in 26 states. Renewable fuels (solar, wind, hydro, geothermal and biomass) account for 14.0% of Maryland's electricity output. These shares describe in-state generation, not a utility-specific customer bill.
Looking back across EIA records, residential prices in Maryland moved from 14.23¢/kWh in 2016 to 19.48¢/kWh in 2025, a 36.9% shift over that window. States charging a similar rate include Pennsylvania, Michigan, Wisconsin, a useful peer set for a sanity check. Because gas sets the price of the marginal megawatt-hour on a grid built around it, Maryland's residential rate tracks the fuel market with a lag: a gas-price winter shows up on bills months later, and a cheap gas year works its way through the same way. Above-average does not mean uniformly expensive. The figure blends every utility in Maryland, and in a state priced at this level the difference between its cheapest and dearest service territories usually matters more to a given bill than the state's rank does.

Maryland Average Price by Sector and Year (¢/kWh)
The chart above tracks households only. In 2025, Maryland households paid 19.48¢/kWh while businesses paid 14.74¢/kWh, a 32.2% residential premium, a wider household-versus-business gap than most states. Every year EIA has published is below, so a single year can be read across all three sectors rather than assembled from three separate EIA queries.

Using Maryland's numbers
With renewables still a small share of generation here, the figures above describe a mix that has further to travel than most. Watch what Maryland builds when its existing thermal capacity retires, because that is the decision the next decade of rates is made of.
- Maryland sits 12.6% above the national average, see exactly where it lands among all 50 states. See the rankings
