Maryland Power Plants and the Environment (CEIR-18)

2.1Electricity Generation in Maryland

Currently in Maryland, 55 power plants with generation capacities greater than 2 megawatts (MW) are interconnected to the regional transmission grid. Table 2‑1 lists the individual power plant sites; Figure 2‑1 shows the plant locations (with the exception of solar installations under 10 MW). In aggregate, Maryland power plants represent over 13,753 MW of operational capacity. The largest portion of Maryland's generating capacity comes from fossil fuels (see Figure 2‑2), with the remainder attributed to nuclear and renewables.

Note: EIA data for generation contains the fossil fuel category, “Other,” which is not included in EIA data for capacity.

MW is equal to 2 million watts, enough power to meet the simultaneous peak demand of about 500 homes.
The generating capacity of a power plant is the maximum amount of power it can instantaneously supply to the grid and is measured in megawatts (MW).Electricity generation is the amount of power supplied through time (energy) and is measured in megawatt-hours (MWh).
Constellation Energy Group merged with Exelon Corporation on March 12, 2012
Through a joint venture with Électricité de France (EDF) called Constellation Nuclear Energy Group, Constellation Energy (which merged with Exelon Corporation) owns 50.1 percent of the Calvert Cliffs nuclear facility.
GenOn Energy, Inc. merged with NRG Energy, Inc. on December 14, 2012.
