Electricity rates & appliance costs in Maryland

Why electricity costs 21.41¢/kWh in Maryland

Summer cooling across the state, winter heating in the western counties.

PJM wholesale markets with regulated delivery; rates above the national average. Retail energy supply is effectively no longer shoppable, so the regulated rate is what most customers pay.

At 21.41¢/kWh, Maryland sits slightly above the 18.3¢ U.S. average. That works out to $214.10 for every 1,000 kWh used — so a 1,500 W space heater costs $0.32 an hour to run, and a family heating with electric resistance instead of gas feels that difference in every winter month.

How Maryland compares with neighbouring states

Maryland ranks 15th of 51 jurisdictions by residential price, from Hawaii at 48.00¢ down to Louisiana at 12.72¢ — a spread of about 3.8× across the country. Identical appliance habits can therefore cost several times more in one state than another.

Across South Atlantic — the regional grouping the EIA itself uses for comparison — the average rate including Maryland is 17.82¢/kWh, so Maryland pays $3.59 more per kWh than that regional average. On a 1,500 W space heater running 6 hours a day, that gap alone is about $984.27 a month.

• Florida15.0¢
• North Carolina15.2¢
• South Carolina15.5¢
• West Virginia15.8¢
• Georgia16.3¢
• Virginia17.6¢
• Delaware18.5¢
• District of Columbia25.2¢

What Maryland households actually pay

A typical U.S. household uses around 30 kWh a day, about 900 kWh a month. At 21.41¢/kWh that is roughly $193 a month in electricity, or $2,312 a year. That is about $28 more per month than the same usage at the national average — a recurring bill difference, not a rounding detail.

Because the rate is a per-kWh price, the fastest savings come from the biggest loads: cutting a 1,500 W space heater from 6 hours a day to 3 saves about $29 a month in Maryland. That is why the calculators here use your state rather than a national guess.

Reading your Maryland utility bill

The EIA figure is a state average across utilities, not your tariff. Your bill shows your exact "price to compare" in ¢/kWh plus fixed customer charges, and sometimes tiered or time-of-use pricing. In a deregulated market you may also have chosen a retail supplier whose rate differs from the utility default.

The calculators use the published state average, which is the right basis for comparing appliances against each other. For a figure that matches your own bill, take the "price to compare" line and use it as your rate.
