Construction of the two Westinghouse pressurized water reactors began in 1974. Unit 1, originally rated at 1,084 MWe, came online on April 17, 1990. In July 2024, the 40-year operating license, which was valid until February 8, 2030, received an early extension for another 20 years, until 2050.[1] Unit 2, 1,124 MWe, followed on April 6, 1993 and is licensed to operate until 2053. Of the nuclear plants to begin construction prior to 1979, Unit 2 was among the last power reactors to come online in the United States, followed only by Units 1 and 2 at Watts Bar. Vogtle Units 3 & 4 were brought online in 2023 and 2024, respectively.
In June 2008, the U.S. Nuclear Regulatory Commission (NRC) approved a request to increase the generating capacity of Units 1 and 2 by approximately 4.5% each.
