Pacific Gas and Electric Company (PG&E) announced on March 20, 2023, that its customers received 96% of their electricity from greenhouse gas-free sources in 2022, making PG&E’s mix among the cleanest electricity portfolios in the world.[1] About 40% of PG&E’s total electricity mix came from renewable resources such as biopower, small hydroelectric, solar, and wind power in 2022. 49% of electricity came from nuclear power generated by Diablo Canyon Power Plant and 7% came from large hydroelectric power.
According to the press release, PG&E was the first energy company to support the California Global Warming Solutions Act of 2006, which set the stage for the state's transition to a sustainable, low-carbon future. PG&E is also planning to exceed the state's requirements under Senate Bill 100, which requires 60% renewables by 2030 and 100% renewables and zero-carbon resources by 2045. PG&E’s Climate Strategy Report outlines the company’s plan to meet California's carbon neutrality goals five years early in 2040 and remove more greenhouse gases than it emits by 2050. Going forward, PG&E plans to deploy thousands of battery energy storage projects through 2025 and beyond. PG&E has contracts for battery energy storage projects totaling more than 3,000 MW of capacity being deployed through 2025. The company is also working to enable electric vehicles to participate in vehicle-to-grid integration programs to support grid reliability and climate resilience.
