21 Maine Yankee Atomic Power Plant

The Maine Yankee nuclear electrical generation plant is located on an 820-acre site in Lincoln County in the Town of Wiscasset, within the mid-coast region of the State of Maine, about 27 miles northeast of Portland. The plant is owned by a consortium of ten New England electric utilities and was operated by the Maine Yankee Atomic Power Company (MYAPCO). During its 24-year operating lifetime, Maine Yankee generated and distributed more than 125 million MW-hours of electrical power.

The construction permit for Maine Yankee was issued on October 21, 1968. The operating license, issued on September 15, 1972, authorized operation of the pressurized water reactor (PWR) facility until October 21, 2008, with power levels up to 75% rated thermal power. Commercial operation began on December 28, 1972. The license granted in June 1973 allowed for operation at 100% rated thermal and at power levels up to and including 2440 MWt.
