350.
(a) For purposes of this section, the following definitions apply:(1) “Avoided transmission cost” means all future transmission-related expenditures that would otherwise be incurred but for the role of distributed generation and storage, including both specific costs of avoided projects and generalized costs not incurred resulting from reduced use of the transmission system.
(2) “Distributed generation” means renewable energy generation interconnected on the utility side of any customer meter on the distribution system used to serve a local load.
(3) “Load serving entity” has the same definition as in Section 380, except that it includes a local publicly owned electric utility.
(4) “Local load” means energy consumption by customers located within the same distribution area below a single transmission-distribution substation.
(5) “Tariff” means a schedule of rates or charges of a business, public utility, or transmission operator.
(6) “Use,” in reference to the transmission system, means the contemporaneous use of the transmission system to deliver energy from generation that requires the transmission system to form an electrical connection to the customer served.
(b) It is the policy of the State of California that:
(1) Load serving entities should receive either direct financial benefit or indirect benefit for their ratepayers for any distributed generation that meets the local load in order to recognize the value of those resources in avoiding transmission costs. The value of avoided transmission costs shall reflect both historic and prospective investments in distributed resources that have mitigated or will mitigate the impacts on the transmission system and relieve the need for transmission investments to the benefit of all California ratepayers.
(2) Regulatory agencies, quasi-regulatory bodies, local agencies, districts, and corporations with jurisdiction or responsibility over transmission and delivery charges should exercise their authorities to provide for a mechanism for load serving entities to receive compensation to reflect the value of avoided transmission costs.
(c) (1) The commission, jointly with the Independent System Operator, and through consultation with all relevant stakeholders, may convene a stakeholder process for the purpose of developing modifications of the tariffs governing transmission access charges, wheeling access charges, or retail rate structures, as necessary to implement the policies specified in subdivision (b). These modifications may include any set of changes to any set of tariffs that is appropriate to implement those policies and conform to the standards set forth in this subdivision.
(2) The modifications of the tariffs developed pursuant to paragraph (1) shall ensure all of the following:
(A) The formulas for cost recovery reflect a combination of all of the following:
(i) Historic factors, drivers, or justifications for a transmission investment at the time the transmission investment is planned or approved.
(ii) Contemporaneous use of the transmission system.
(iii) Incentives to mitigate drivers of future transmission investment.
(B) Transmission system charges are predominantly assessed on use of transmission system capacity based on the amount of energy delivered across the transmission system.
(C) Supplying electrical load with distribution-connected generation or other distribution system technologies within the same substation area that offsets the contemporaneous use of transmission system capacity results in financial credits to the load serving entities responsible for the deployment of the resources or to their customers.
(D) The basis for applying access charges to each distribution utility, community choice aggregation program, local publicly owned electric utility, and electric service provider is consistent in a manner that fully compensates each of those entities for the distributed generation within the entity’s distribution grid, unless the commission and Independent System Operator each makes a finding, based on substantial evidence, that differential bases are in the best interest of all California end-use electricity customers and further the achievement of California’s environmental goals, including the California Renewables Portfolio Standard Program (Article 16 (commencing with Section 399.11)) and the California Global Warming Solutions Act of 2006 (Division 25.5 (commencing with Section 38500) of the Health and Safety Code).
(E) Transmission charges recognize the value provided by distributed energy resources including, but not limited to, the economic, environmental, and system resiliency benefits of distributed resources, and the potential to reduce the use of existing transmission infrastructure and the need for future transmission infrastructure and capacity.
(3) Any rate structure for allocating transmission costs shall be based upon factual findings supported by a preponderance of evidence, and the analytical path from evidence to finding shall be readily discernible. Evidence for these purposes shall not include argument, speculation, unsubstantiated opinion or narrative, or evidence that is clearly erroneous or inaccurate.
(4) (A) If the stakeholder process is undertaken pursuant to this subdivision, the final set of modifications to implement the policies specified in subdivision (b) shall be completed by July 1, 2020.
(B) Each commission, board, corporation, or agency with authority over modifications in the final set shall approve modifications to those tariffs or rules under its jurisdiction by October 31, 2020.
(C) Once approved, any element of the final set of modifications requiring approval by the Federal Energy Regulatory Commission shall be submitted by the relevant commission, board, corporation, or agency, by January 1, 2021, to the Federal Energy Regulatory Commission for approval.
(D) Within one year of the date of approval by the Federal Energy Regulatory Commission of submitted elements of the final set of modifications, the Independent System Operator, the commission, each electrical corporation, and any other load serving entity with jurisdiction over elements of the set of modifications shall fully implement all modifications to the tariffs and rules identified and approved to meet the policies specified in paragraph (b).
(d) (1) If no final set of modifications meeting the standards in paragraph (2) of subdivision (c) has been approved by October 31, 2020, each of the electrical corporations that recovers transmission charges from the customers of more than one load serving entity shall modify its rules and tariffs to accomplish the following:
(A) The customers of each load serving entity shall make up separate retail rate classes from the customers of any other load serving entity for the purposes of assessing transmission fees and cost allocation, for both transmission charges from the Independent System Operator and for the electrical corporation’s own transmission revenue requirements.
(B) Transmission charges shall be billed to customers clearly and understandably as a separate component from any other component of delivery or generation charges on customer bills.
(C) All customer transmission charges and components of those charges shall be reduced by the proportion of energy provided by that customer’s load serving entity as distributed generation serving a local load.
(D) Each electrical corporation recovering transmission charges from customers of more than one load serving entity shall recover a customer’s transmission charges reduced by the proportion of energy generated by distributed generation serving the local load of that customer’s load serving entity.
(2) The modifications and any attendant implementing rules required shall be submitted to Federal Energy Regulatory Commission no later than January 1, 2021.
