Diablo Canyon Power Plant, which sits on approximately 1,000 acres on the Pacific coast, has operated safely since 1985 with its two Westinghouse Pressurized Water Reactor (PWR) units that are licensed until 2024 and 2025 respectively.
The two units produce a total of 18,000 gigawatt-hours of clean and reliable electricity annually, which is enough energy to meet the needs of more than three million Northern and Central Californians (nearly 10% of California's energy portfolio and 20% of the power that PG&E provides throughout its service area).
For 30 years, Diablo Canyon has continued to safely produce clean and reliable energy without greenhouse gases (GHG), avoiding 6 to 7 million tons per year of GHGs that would be emitted by conventional generation resources. Built to withstand extreme natural disasters, including earthquakes, Diablo Canyon’s design features state-of-the-art seismic supports.
The facility is continually inspected and assessed by Nuclear Regulatory Commission inspectors, to ensure that the facility’s systems are operating safely and efficiently each and every day.
