The North Anna Nuclear Generating Station is a nuclear power plant on a 1,075-acre (435 ha) site in Louisa County, Virginia, in the Mid-Atlantic United States. The site is operated by Dominion Generation company and is jointly owned by the Dominion Virginia Power corporation (88.4%) and by the Old Dominion Electric Cooperative (11.6%).
The plant has two Westinghouse pressurized water reactors which went on-line in 1978 and 1980, respectively. Together the reactors generate 1.79 gigawatts of power, which is distributed mainly to the greater Richmond area and to Northern Virginia. In March 2003, the Nuclear Regulatory Commission approved 20 year license extensions for both Units 1 & 2.[2][needs update] Subsequent license applications for both units were submitted in 2020. The Nuclear Regulatory Commission approved the license for both Units 1 & 2 in August, 2024.[3] Unit 1's license will expire on April 1, 2058 and Unit 2's license will expire on August 21, 2060.[3]
An artificial lake, Lake Anna, was constructed on the North Anna River to provide a reservoir of water coolant for use with the nuclear plant.
Dominion Energy currently owns nuclear power plants in Virginia (North Anna, Surry), Connecticut (Millstone), South Carolina (Virgil C. Summer Nuclear Generating Station), and Wisconsin (Kewaunee). North Anna is similar in design and appearance to Surry Power Station.
