380.
(a) The commission, in consultation with the Independent System Operator, shall establish resource adequacy requirements for all load-serving entities.(b) In establishing resource adequacy requirements, the commission shall ensure the reliability of electrical service in California while advancing, to the extent possible, the state’s goals for clean energy, reducing air pollution, and reducing emissions of greenhouse gases. The resource adequacy program shall achieve all of the following objectives:
(1) Facilitate development of new generating, nongenerating, and hybrid capacity and retention of existing generating, nongenerating,
and hybrid capacity that is economic and needed.
(2) Establish new or maintain existing demand response products and tariffs that facilitate the economic dispatch and use of demand response that can either meet or reduce an electrical corporation’s resource adequacy requirements, as determined by the commission. In furtherance of this purpose, the commission shall do all the following by July 1, 2021:
(A)Charging of energy storage systems shall be treated as load in baseline calculations for demand response programs supporting this objective.
(B)The commission shall allow capacity from energy storage systems installed on the customer side of the meter to be aggregated for purposes of determining resource adequacy capacity, and shall allow electricity exported to the electrical grid from behind the meter to count toward the capacity obligations of load-serving entities in
support of this objective.
(A) Establish rules that allow demand response programs and resources procured by a load-serving entity to meet the load-serving entity’s resource adequacy requirements regardless of whether the program is integrated into the wholesale market overseen by the Independent System Operator.
(B) Adopt a baseline methodology that treats the charging of energy storage as load in baseline calculations for demand response programs supporting this objective.
(C) Allow customer-sited distributed eligible renewable energy resources and energy storage systems participating in a demand response program, or product developed pursuant to subparagraph (A), to deliver electricity to the grid for purposes
of providing resource adequacy.
(D) Ensure that the capacity valuation developed pursuant to subdivision (k) applies to demand response resources coupled with customer-sited hybrid or customer-sited storage resources.
(3) Equitably allocate the cost of generating capacity and demand response in a manner that prevents the shifting of costs between customer classes.
(4) Minimize enforcement requirements and costs.
(5) Maximize the ability of community choice aggregators to determine the generation resources used to serve their customers.
(c) Each load-serving entity shall maintain physical generating capacity and electrical demand response adequate to meet its load requirements, including, but not limited to, peak demand and planning and operating reserves. The generating capacity or electrical demand response shall be deliverable to locations and at times as may be necessary to maintain electrical service system
reliability, local area reliability, and flexibility.
(d) Each load-serving entity shall, at a minimum, meet the most recent minimum planning reserve and reliability criteria approved by the Board of Directors of the Western Systems Coordinating Council or the Western Electricity Coordinating Council.
(e) The commission shall implement and enforce the resource adequacy requirements established in accordance with this section in a nondiscriminatory manner. Each load-serving entity shall be subject to the same requirements for resource adequacy and the renewables portfolio standard program that are applicable to electrical corporations pursuant to this section, or otherwise required by law, or by order or decision of the commission. The commission shall exercise its
enforcement powers to ensure compliance by all load-serving entities.
(f) The commission shall require sufficient information, including, but not limited to, anticipated load, actual load, and measures undertaken by a load-serving entity to ensure resource adequacy, to be reported to enable the commission to determine compliance with the resource adequacy requirements established by the commission.
(g) An electrical corporation’s costs of meeting or reducing resource adequacy requirements, including, but not limited to, the costs associated with system reliability, local area reliability, and flexibility, that are determined to be reasonable by the commission, or are otherwise recoverable under a procurement plan approved by the commission pursuant to Section 454.5, shall be
fully recoverable from those customers on whose behalf the costs are incurred, as determined by the commission, at the time the commitment to incur the cost is made, on a fully nonbypassable basis, as determined by the commission. The commission shall exclude any amounts authorized to be recovered pursuant to Section 366.2 when authorizing the amount of costs to be recovered from customers of a community choice aggregator or from customers that purchase electricity through a direct transaction pursuant to this subdivision.
(h) The commission shall determine and authorize the most efficient and equitable means for achieving all of the following:
(1) Meeting the objectives of this section.
(2) Ensuring that investment is
made in new generating capacity.
(3) Ensuring that existing generating capacity that is economic is retained.
(4) Ensuring that the cost of generating capacity and demand response is allocated equitably.
(5) Ensuring that community choice aggregators can determine the generation resources used to serve their customers.
(6) Ensuring that investments are made in new and existing demand response resources that are cost effective and help to achieve electrical grid reliability and the state’s goals for reducing emissions of greenhouse gases.
(7) Minimizing the need for backstop procurement by the Independent
System Operator.
(i) In making the determination pursuant to subdivision (h), the commission may consider a centralized resource adequacy mechanism among other options.
(j) The commission shall ensure appropriate valuation of both supply and load modifying demand response resources. The commission, in an existing or new proceeding, shall establish a mechanism to value load modifying demand response resources, including, but not limited to, the ability of demand response resources to help meet distribution needs and transmission system needs and to help reduce a load-serving entity’s resource adequacy obligation pursuant to this section. In determining this value, the commission shall consider how these resources further the state’s electrical grid reliability and the
state’s goals for reducing emissions of greenhouse gases. The commission, Energy Commission, and Independent System Operator shall jointly ensure that changes in demand caused by load modifying demand response are expeditiously and comprehensively reflected in the Energy Commission’s Integrated Energy Policy Report forecast, as well as in planning proceedings and associated analyses, and shall encourage reflection of these changes in demand in the operation of the grid.
(k) The commission, in consultation with the Independent System Operator and the Energy Commission, shall establish a capacity valuation methodology for customer-sited energy storage resources and customer-sited hybrid resources. In determining this value, the commission shall incorporate the full electrical output of the resource, including
all electricity delivered to the grid. The commission shall adopt the capacity valuation methodology by no later than July 1, 2021, for the 2022 resource adequacy year.
(k)For purposes of this section, “load-serving
(l) For purposes of this section, the following terms have the following meanings:
(1) “Hybrid resource” means an energy storage system, as defined in Section 2838.2, that is paired with a colocated eligible renewable energy resource where the energy storage system
obtains charging energy from that colocated eligible renewable energy resource.
(2) “Load-serving entity” means an electrical corporation, electric service provider, or community choice aggregator. “Load-serving entity” does not include any of the following:
(1)
(A) A local publicly owned electric utility.
(2)
(B) The State Water Resources Development System commonly known as the State Water Project.
(3)
(C) Customer generation located on the customer’s site or providing electric service through arrangements authorized by Section 218, if the customer generation, or the load it serves, meets one of the following criteria:
(A)
(i) It takes standby service from the electrical corporation on a commission-approved rate schedule that provides for adequate backup planning and operating reserves for the standby customer class.
(B)
(ii) It is not physically interconnected to the electrical transmission or distribution grid, so that, if the customer generation fails, backup electricity is not supplied from the electrical grid.
(C)
(iii) There is physical assurance that the load served by the customer generation will be curtailed concurrently and commensurately with an outage of the customer generation.
