1Municipal Solid Waste net generation is allocated according to the biogenic and non-biogenic components of the fuel; however, all Municipal Solid Waste summer capacity is classified as Renewable.
Notes: Totals may not equal sum of components due to independent rounding.
Other: Blast furnace gas, propane gas, other manufactured and waste gases derived from fossil fuels, non-biogenic municipal solid waste, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, tire-derived fuel, and miscellaneous technologies.
Other Renewable: Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal, photovoltaic energy, and wind.

Operator: Calvert Cliffs Nuclear Power Plant, LLC

Location and Service Territory: Calvert Cliffs Nuclear Power Plant is located in Lusby on the western shore of Chesapeake Bay.

Construction Cost: $2.206 billion (2007 USD)2

Reactor Descriptions: Both units are Combustion Engineering two-loop pressurized water reactors.

Cooling System: The Chesapeake Bay is used as a heat-sink in the plant’s once-through cooling system.
