454.53.
(a) It is the policy of the state that eligible renewable energy resources and zero-carbon resources supply 100 percent of all retail sales of electricity to California end-use customers and 100 percent of electricity procured to serve all state agencies by December 31, 2045. The achievement of this policy for California shall not increase carbon emissions elsewhere in the western grid and shall not allow resource shuffling. The commission and Energy Commission, in consultation with the State Air Resources Board, shall take steps to ensure that a transition to a zero-carbon electric system for the State of California does not cause or contribute to greenhouse gas emissions increases elsewhere in the western grid, and is undertaken in a manner
consistent with clause 3 of Section 8 of Article I of the United States Constitution. The commission, the Energy Commission, the State Air Resources Board, and all other state agencies shall incorporate this policy into all relevant planning.(b) The commission, Energy Commission, State Air Resources Board, and all other state agencies shall ensure that actions taken in furtherance of subdivision (a) do all of the following:
(1) Maintain and protect the safety, reliable operation, and balancing of the electric system.
(2) Prevent unreasonable impacts to electricity, gas, and water customer rates and bills resulting from implementation of this section, taking into full consideration the economic and
environmental costs and benefits of renewable energy and zero-carbon resources.
(3) To the extent feasible and authorized under law, lead to the adoption of policies and taking of actions in other sectors to obtain greenhouse gas emission reductions that ensure equity between other sectors and the electricity sector.
(4) Not affect in any manner the rules and requirements for the oversight of, and enforcement against, retail sellers and local publicly owned utilities pursuant to the California Renewables Portfolio Standard Program (Article 16 (commencing with Section 399.11) of Chapter 2.3) and Sections 454.51, 454.52, 9621, and 9622.
(c) This section does not affect a retail seller’s obligation
to comply with the federal Public Utility Regulatory Policies Act of 1978 (16 U.S.C. Sec. 2601 et seq.).
(d) The commission, Energy Commission, and State Air Resources Board shall do all of the following:
(1) Use programs authorized under existing statutes to achieve the policy described in subdivision (a).
(2) In consultation with all California balancing authorities, as defined in subdivision (d) of Section 399.12, as part of a public process, issue a joint report to the Legislature by January 1, 2021, and at least every four years thereafter. The joint report shall include all of the following:
(A) A review of the policy described in subdivision (a) focused on
technologies, forecasts, then-existing transmission, and maintaining safety, environmental and public safety protection, affordability, and system and local reliability.
(B) An evaluation identifying the potential benefits and impacts on system and local reliability associated with achieving the policy described in subdivision (a).
(C) An evaluation identifying the nature of any anticipated financial costs and benefits to electric, gas, and water utilities, including customer rate impacts and benefits.
(D) The barriers to, and benefits of, achieving the policy described in subdivision (a).
(E) Alternative scenarios in which the policy described in subdivision
(a) can be achieved and the estimated costs and benefits of each scenario.
(3) In consultation with all California balancing authorities, as defined in Section 399.12, develop a strategy by ____ January 1, 2024, on how to achieve the policy described in subdivision (a) in a cost-effective and environmentally beneficial manner. The strategy shall do all both of the following:
(A)Consider the factors, including, but not limited to, interregional renewable power generation, short-term energy storage, seasonal energy storage, and carbon capture and storage, that affect the ability to achieve the policy described in subdivision (a). The energy storage methods considered by the strategy shall include, but are not limited to, batteries, pumped storage, hydrogen generation and storage, and other developing
technologies.
(B)Include a plan to promote the development of technologies that can help achieve the policy described in subdivision (a) to determine the feasibility of those technologies.
(C)Include a plan for how feasible technologies can be deployed in a manner that would achieve the policy described in subdivision (a).
(A) Achieve a target of at least five gigawatthours of operational long-term backup electricity by December 31, 2030, from resources that include long-duration energy storage facilities,
and a more robust combination of eligible renewable energy resources, such as geothermal generation and more reliable wind generation. The long-duration energy storage methods considered by the strategy shall include, but are not limited to, flow batteries, pumped hydroelectric storage, hydrogen generation and storage, and other developing technologies. Included in the strategy shall be a plan to promote the development of technologies that can help achieve the policy described in subdivision (a), the means to determine the feasibility of those technologies, and how the feasible technologies can be deployed in a manner that will achieve the policy described in subdivision (a). The strategy shall address carbon sequestration and storage of emissions from conventional powerplants.
(B) Achieve a target of at least an additional five
gigawatthours of operational long-term backup electricity in each subsequent year beginning 2031 through 2045, inclusive.
(e) This section does not authorize the commission to establish any requirements on a nonmobile self-cogeneration or cogeneration facility that served onsite load, or that served load pursuant to an over-the-fence arrangement if that arrangement existed on or before December 20, 1995.
