How Maryland compares
At 20.6¢/kWh, Maryland has the 13th-highest residential electricity price of the 50 states and DC — 12% above the 18.4¢ US average. That's close to typical for the US — neither a bargain nor a burden by national standards. For context, the cheapest power in this data is Idaho at 12.3¢, and the most expensive is Hawaii at 41.1¢.
Over the period in the chart above, Maryland's average rate has risen about 37% — in line with a long national trend of electricity prices climbing faster than they used to, driven by grid upgrades, fuel costs and surging demand.
What your rate means for the big decisions
Your electricity price is the single number that drives whether solar, an EV, or electric heating saves you money. At Maryland's 20.6¢/kWh:
- Rooftop solar pays back in about 10.2 years for a typical home here — roughly the national middle. See the full breakdown on the Maryland solar payback page, including local utilities, net metering and incentives.
- Charging an EV at home costs about 7.5¢ per mile here, versus roughly 12.2¢/mile for a typical petrol car — see the Maryland EV charging breakdown.
- Cooling and heating swing with this rate too — check what running your AC costs in Maryland, or whether a heat pump beats gas at 20.6¢/kWh.
