AB 305

This bill makes significant changes to California's nuclear energy policy by exempting small modular reactors (SMRs) from the state's existing prohibition on certifying new nuclear fission thermal power plants, effectively allowing these smaller nuclear facilities to be built and operated in California. Additionally, the bill mandates the Public Utilities Commission to develop a plan by January 1, 2028, that increases electricity procurement from nuclear facilities while phasing out electricity generated from natural gas plants. This represents a major shift in California's energy strategy, positioning nuclear power—particularly through SMRs—as a key replacement for natural gas in the state's transition to zero-carbon electricity, complementing the existing goal of achieving 100% renewable and zero-carbon electricity by 2045.
