Diablo Canyon Nuclear Power Plant, California

Operated by Pacific Gas & Electric (PG&E), the plant hosts two 1,100MW pressurized water reactors, producing around 18,000 gigawatt-hours of electricity a year. Construction began in the late 1960's, with Units 1 & 2 becoming operational in 1985 and 1986 respectively. Long plagued by controversy due to its location along a particularly scenic stretch of coastline, as well as its proximity to multiple known earthquake faults, it is currently the only functioning nuclear power plant in California. In 2016, PG&E announced its intention to close the plant by 2025, due in large part to changes in California's energy marketplace, which have rendered electricity produced by nuclear power noncompetitive with various renewable sources.
