Under a proposal announced on June 21, 2016 by Pacific Gas and Electric, the Diablo Canyon Power Plant, the states last operating nuclear facility, would be shuttered by PG&E after its current Nuclear Regulatory Commission operating licenses expire in November 2024 and August 2025. The power produced by Diablo Canyons two nuclear reactors would be replaced with investment in a greenhouse-gas-free portfolio of energy efficiency, renewables and energy storage, PG&E said in a statement. The power output loss would be compensated by using technologies that do not emit greenhouse gases, including renewable energy.
