| 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.

Plants in State
Operator: Dominion Nuclear Connecticut
Location and Service Territory: The power plant is located on Millstone Point, a peninsula near Waterford, Connecticut. The 500-acre site was formerly a granite quarry.
Construction Cost: $8.845 billion (2007 USD)2
Reactor Descriptions: Millstone 2 and Millstone 3 are pressurized water reactors. Millstone 2 was supplied by Combustion Engineering. Millstone 3 is a Westinghouse four-loop reactor.
Cooling System: The Millstone plant draws water from Long Island Sound for its once-through cooling system.
