Where the electricity in Maryland comes from
The largest source of the electricity generated in Maryland in 2024 was nuclear power, according to the Energy Information Administration's state profile. Nuclear plants are expensive to build but cheap and steady to run, so they tend to hold prices stable. They run around the clock regardless of the weather or the price of gas.
Power plants here generated 35.4 million MWh in 2024, less than the 59.0 million MWh sold to customers, so part of the electricity used is brought in from neighboring states.
How the climate shapes bills
Maryland has both a real winter and a hot, humid summer, so homes run heating and cooling in different seasons. Electricity use usually peaks in July and August, with a second, smaller peak in winter for homes with electric heat or heat pumps.
That is why the same price per kWh can produce very different bills in two homes: the price tells you what each kWh costs, and the weather and your heating and cooling equipment decide how many you use. To see the effect of one appliance, compare a window air conditioner, a space heater and a heat pump in the table above.
Can you choose your electricity supplier?
Yes. Maryland is one of the places where households can choose the company that supplies their electricity, while the local utility still delivers it. If you have signed up with a supplier, the price on your bill can be noticeably higher or lower than the state average shown here. Check the supply rate on your latest bill and type it into the calculator. The Energy Information Administration counts 13 states and the District of Columbia with active residential retail choice programs, plus Texas, where choosing a retail provider is mandatory in most of the state.
