In 2022, Maryland had a total summer capacity of 11,908 MW through all of its power plants, and a net generation of 37,139 GWh.
[2] In 2023, the electrical energy generation mix was 42.5% natural gas, 41.6% nuclear, 5.2% hydroelectric, 4.7% coal, 2.7% solar, 1.3% wind, 0.9% biomass, 0.2% petroleum, and 0.9% other.
Small-scale solar, which includes customer-owned PV panels, delivered an additional net 1,404 GWh of energy to Maryland's electrical grid in 2023.
This was nearly 50 percent more than the generation of the state's utility-scale PV plants.
