4 Environmental Analysis 4.6 Energy manufacturing, and put the U.S. on a pathway to achieving the Biden Administration's climate goals, including a net-zero economy by 2050. 4.6.2.2 State Warren-Alquist Act The 1975 Warren-Alquist Act (Public Resources Code § 25000 et seq.) established the California Energy Resources Conservation and Development Commission, now known as the CEC. The act established a state policy to reduce wasteful, uneconomical, and unnecessary uses of energy by employing a range of measures. Renewables Portfolio Standard California's Renewables Portfolio Standard (RPS) Program was enacted in 2002 with Senate Bill (SB) 1078 and accelerated in 2006, requiring investor-owned utilities to obtain 20 percent of their electric supply from renewable energy sources, such as solar, by 2010. On April 12, 2011, Governor Brown signed SB 2X, requiring California retail electric providers, such as PG&E, to procure 33 percent of their retail energy sales from eligible renewable sources by 2020. In October 2015, Governor Brown signed into legislation SB 350, which requires retail sellers and publicly owned utilities to procure 50 percent of their electricity from eligible renewable energy resources by 2030 (CPUC 2021 a). On September 10, 2018, Governor Brown signed SB 100, establishing that 100 percent of all electricity in California must be obtained from renewable and zero-carbon energy resources by December 31, 2045. SB 100 also created new standards for the RPS goals that were established by SB 350 in 2015. Specifically, the bill increases required energy from renewable sources for both investor-owned and publicly owned utilities from 50 percent to 60 percent by 2030. Incrementally, these energy providers also are required to have a renewable energy supply of 33 percent by 2020, 44 percent by 2024, and 52 percent by 2027. The updated RPS goals are considered achievable, since many California energy providers are already meeting or exceeding the RPS goals established by SB 350. Governor Brown signed Executive Order B-55-18 with a new statewide goal to achieve carbon neutrality (i.e., net-zero GHG emissions) by 2045 and to maintain net negative emissions thereafter. On September 16, 2022, Governor Newsom signed SB 1020, the Clean Energy, Jobs and Affordability Act, which adds interim targets to the policy framework originally established in SB 100. The interim targets require renewable energy and zero-carbon resources to supply 90 percent of all retail electricity sales by 2035 and 95 percent of all retail electricity sales by 2040. The bill also requires all state agencies to rely on 100 percent renewable energy and zero-carbon resources to power their own facilities by 2035 and encourages better information sharing and coordination between agencies for transmission planning. Energy Storage Assembly Bill (AB) 2514, passed in 2010, resulted in the CPUC setting a 1,325-megwatt (MW) storage target by 2020 for investor-owned utilities. The three major investor-owned utilities in the state, including PG&E, have exceeded the AB 2514 target of 1,325 MW. AB 2868, passed in 2016, requires California's three major investor-owned utilities to propose programs and Griffith Energy Storage Project 4.6-3 Tetra Tech/SCH 2022120675 Draft Environmental Impact Report August 2023
