North Anna

North Anna Power Station is a Dominion Energy nuclear generating facility located in Louisa County, Virginia, on the southern shore of Lake Anna. It comprises two Westinghouse pressurised-water reactors: Unit 1 (883 MW net) online since 1978 and Unit 2 (900 MW net) online since 1980, giving a combined capacity of approximately 1,892 MW. The plant accounts for roughly a quarter of Dominion's Virginia generating capacity and supplies carbon-free baseload power to the Northern Virginia grid, which includes the data-centre corridor.

The station uses Lake Anna as its primary condenser-cooling source: large volumes of lake water are drawn through intake structures, passed over the condenser coils, and discharged back into the reservoir at higher temperature. Dominion applied for a 20-year operating licence extension from the Nuclear Regulatory Commission (NRC); Units 1 and 2 are currently licensed through 2038 and 2040 respectively. A second licence renewal would extend operation into the 2050s. The site also stores spent nuclear fuel in an Independent Spent Fuel Storage Installation (ISFSI) on the plant footprint.

Amazon's proposed 150-acre data-centre campus in Louisa County sits directly adjacent to North Anna. The co-location is deliberate: proximity to the plant's switchyard reduces transmission losses for the high-power campus. It also brings the two facilities into the same water-use environment: both draw on Lake Anna's cooling capacity, and Amazon's VPDES permit application proposes discharging up to 280,000 gallons a day of non-contact cooling water into Sedges Creek, a Lake Anna tributary, raising questions about cumulative thermal and chemical loading on the reservoir that Dominion must manage for NRC-regulated cooling-water standards .
