  • Application

    Evaluation of Distributed Energy Resources

  • Date

    March 2018
  • Details

    On May 16, 2019, the California Public Utilities Commission (CPUC) issued a final order requiring the use of the SCC for evaluating distributed energy resources (DERs). Specifically, utilities must conduct a societal cost test (SCT) in resource planning that is comprised of three parts, one of which is the "avoided social cost of carbon." The final order requires utilities to model the SCT using two SCC values, the 3% estimate and high-impact estimate.

  • SCC Value(s)

    e.g. $123/Mt CO2e for 2020 emissions (2016 IWG SCC high-impact values, 3% discount rate). 1

  • Reference

    Rulemaking 14-10-003: Order Instituting Rulemaking to Create a Consistent Regulatory Framework for the Guidance, Planning and Evaluation of Integrated Distributed Energy Resources.

  • Litigation


  • Status

    Order effective through December 2020.
