California's last nuclear power plant to close by 2025

California's only remaining nuclear power plant, the Diablo Canyon plant near San Luis Obispo, will begin closing in 2025, state regulators announced.

The closing by utility Pacific Gas and Electric Co. will likely mean a rise in monthly consumer electric bills. PG&E spokesperson Blair Jones estimated a 0.5 percent annual increase on Thursday. The power plant is San Luis Obispo County's fourth-largest employer, with 1,500 employees, and PG&E will shift payment of $241.2 million in shutdown costs to consumers, the San Francisco Chronicle reported on Thursday.

The two 1,100-megawatt reactors went online in 1985 and 1986, and produce nearly nine percent of the state's electricity, serving three million people. The reactors will be deactivated in 2025 and 2026, when their U.S. Nuclear Regulatory Commission operating licenses expire.
