The Maine Yankee Atomic Power plant was built between 1968 and 1972 at a reported cost of $231 million in Wiscasset. The site offered access to fresh and salt water, rail and highway connections, nearby electrical demand and transmission lines, and bedrock suitable for foundations.
Power and local prosperity
During its operating life, the plant was Maine’s largest generator of electricity. It produced approximately 119 billion kilowatt-hours for Maine and the wider New England power system.
The facility also transformed municipal finances. Its property-tax payments supported local services and helped fund improvements to schools, parks, roads, public safety, a community center, and ambulance service. Its workforce of roughly 480 full-time employees contributed additional spending to the local economy.
Debate, shutdown, and closure
Maine Yankee operated from 1972 to 1996. It remained open after three statewide citizen-initiated ballot measures in 1980, 1987, and 1992 sought to close it.
The plant shut down in 1995 after cracks were found in steam-generator tubes. It did not return to sustained operation. In August 1997, the company chose permanent closure and decommissioning.
Dismantling the station
Major dismantling continued into the next decade. In 2004, remaining structures were demolished and material was transported to disposal facilities outside Maine. The reactor pressure vessel traveled by barge to a low-level radioactive-waste facility in Barnwell, South Carolina. The reported decommissioning cost was approximately $568 million.
Spent nuclear fuel remained in secure interim storage at the former plant site after decommissioning. This distinction is important: dismantling a generating station does not by itself resolve the long-term disposition of its spent fuel.
Economic aftermath
Closure removed a major source of tax revenue and employment from Wiscasset. The town consequently faced budget reductions and higher taxes while adjusting its services and finances to the loss of the plant.
The Maine Yankee story connects energy production, industrial regulation, local government, employment, environmental management, and the long obligations that follow a nuclear facility’s operating life.
