Diablo Canyon Power Plant Decommissioning

In 2021, Pacific Gas and Electric Company (PG&E) filed a land use permit application and additional informational supplements to the County of San Luis Obispo (County) for the planned decommissioning of PG&E’s 2,200 MW Diablo Canyon Power Plant. The power plant’s Nuclear Regulatory Commission operating licenses currently expire in 2024 and 2025, for Unit 1 and Unit 2, respectively.

On September 2, 2022, Governor Gavin Newsom signed SB 846 (Dodd, 2022) into law, providing PG&E a path to continue operating the Diablo Canyon Power Plant through 2030.

The County has been actively engaged in the state legislative and regulatory processes regarding the future of DCPP. As the host community for the plant, the County continues to work with federal, state, and local partners to plan for the future of DCPP and the lands that surround it. The plant plays a significant role in the County’s economy and community, and the County is working to ensure the community’s interests are represented in the safety, environmental, and other regulatory processes and decisions that lie ahead.

The County has also been moving forward with preparing the Environmental Impact Report (EIR) for the decommissioning of Diablo Canyon Power Plant.
