Millstone Power Station

Millstone Power StationMillstone Power Station, located in southeast Connecticut, generates enough electricity from its two operational units to power about 500,000 homes.

Unit 1 began commercial operation in December 1970, and ceased operating in July 1998. It is being decommissioned. Unit 2 began commercial operation in December 1975, and it generates 869.5 megawatts. Unit 3, which began operating in April 1986, generates 1,210 megawatts. Dominion acquired the station in March 2001.

Situated three miles west-southwest of New London, Millstone was named after the site’s historic granite quarry that produced high-quality millstones and structural building granite.
