Publicly Owned Utility
Integrated Resource Plans

Senate Bill 350 (de Leon, Chapter 547, Statutes of 2015) (SB 350) requires publicly owned utilities (POU) with an average load greater than 700 GWh (in the 2013-16 period) to adopt Integrated Resource Plans (IRP) by January 1, 2019, submit them to the Energy Commission, and update them at least once every five years thereafter. Based on historical data, 16 POUs are required to file an IRP. The Energy Commission is required to review POU IRPs for consistency with Public Utilities Code 9621 and recommend corrections to deficiencies in the plans, and may adopt guidelines to "govern the submission of information" for this review. The Energy Commission formally adopted guidelines August 9, 2017. The current versions of the Publicly Owned Utility Integrated Resource Plan Submission and Review Guidelines and standardized reporting tables were revised in October 2018.

IRPs are electricity system planning documents intended to ensure that POUs lay out the resource needs, policy goals, physical and operational constraints, and general priorities or proposed resource choices of an electric utility, including customer-side preferred resources. These plans will provide a framework to evaluate how utilities have chosen to align with greenhouse gas emission reduction targets as well as energy and other policy goals outlined in SB 350, including but not limited to:

  • Reductions in electricity sector greenhouse gas emissions commensurate with economy-wide reductions of 40 percent from 1990 levels by 2030;
  • A Renewables Portfolio Standard of 50 percent by 2030; and
  • Energy efficiency, storage, vehicle electrification, and other electricity resources

Parties interested in information regarding actions, hearings, or meetings that publicly owned utilities (POU) will hold related to the development of their respective integrated resource plans (IRP) should visit the POU Planning Activities webpage.

Interested parties may sign up for the CEC Integrated Resource Plans List Serve (to the right). This list serve will provide notification of all documents, notices, and decisions posted to the docket of this proceeding.

Light-Duty Plug-in Electric Vehicle (LD PEV) Energy and Emissions Calculator
POUs are required to address transportation electrification in the IRPs adopted and submitted to the Energy Commission pursuant to SB 350. At the request of the POUs, Energy Commission staff has developed a spreadsheet-based tool to assist POUs in estimating and reporting on the energy and emissions impact of light-duty plug-in electric vehicle (LD PEV) deployment in their service territories. Use of this tool is to address transportation electrification is optional.
The calculator and a description of it can be found here Light duty PEV Energy and Emission Calculator (version 3.5-3, xlsx File, 5.2 MB)
