Satsop is known for the unfinished Satsop Nuclear Power Plant, a facility designed to house two 1250 megawatt pressurized water reactors. Construction of the Satsop Nuclear Power Plant began in 1977 and was halted in 1983 after a $961 million budget shortfall, leaving the plant 76% complete. The plant was maintained, ready for construction to be resumed, until 1994, when it was finally canceled. In 1995, a demolition plan was finalized that eventually turned the site into the Satsop Development Park.
Because of the controversy surrounding the construction and cancelation of the power plant, the facility is known locally as "Whoops", a play on its official acronym, WPPSS (Washington Public Power Supply System).
