Pilgrim Nuclear Power Station (PNPS) is the only nuclear power plant operating in Massachusetts. It is located in the Manomet section of Plymouth on Cape Cod Bay, south of the tip of Rocky Point and north of Priscilla Beach. Like many similar plants, it was constructed by Bechtel, and is powered by a General Electric BWR 3 boiling water reactor inside of a Mark 1 pressure suppression type containment and generator. It has a 690 MW production capacity. Pilgrim Station produces about 14% of the electricity generated in Massachusetts.
On October 13, 2015, plant owners announced that it would close by June 2019, citing "market conditions and increased costs," which would have included tens of millions of dollars of necessary safety upgrades.
Built at a cost of $231 million in 1972 by Boston Edison, it was sold in 1999 to the Louisiana-based Entergy Corporation, part of a complex deal that is the result of deregulation of the electrical utility industry.
On April 11, 1986, a recurring equipment problem forced emergency shutdown of the plant.
Pilgrim keeps its spent nuclear fuel in an on-site storage pool, waiting for federal direction on the correct disposal process. The Yucca Mountain site in Nevada was being considered for this purpose until its deselection in 2009.
