Current Proceeding

R.15-03-011

On April 2, 2015, the California Public Utilities (CPUC or Commission) opened this Order Instituting Rulemaking (OIR) in response to the enactment and ongoing implementation of legislation Assembly Bill 2514 (Skinner, Stats.2010 - ch. 469) and to continue to refine policies and program details as required or recommended by Decision (D.)13-10-040 and D.14-10-045, which established the Energy Storage Procurement Framework and Program and approved the utilities' applications in implementing the program.  This rulemaking considers recommendations included in the California Energy Storage Roadmap, an interagency guidance document which was jointly developed by the California Independent System Operator, the California Energy Commission and the CPUC.

Pre-Hearing Conference was held on May 20, 2015, at 10:00 a.m., in the Commission Courtroom, State Office Building, 505 Van Ness Avenue, San Francisco, California.

Proceeding information and Comments filed by the parties in R.15-03-011, can be accessed via Commission's Docket search link.

Chronology of events and Proceedings

In December 2010, the CPUC opened Rulemaking R.10-12-007 to set policy for California utilities and load-serving entities (LSEs) to consider the procurement of viable and cost-effective energy storage systems.

Under terms of state law embodied in AB 2514 (Skinner), by October 1, 2013, the CPUC shall adopt an energy storage procurement target, if determined to be appropriate, to be achieved by each LSE by December 15, 2015, and a 2nd target to be achieved by December 31, 2020.

In addition, the CPUC should consider a variety of possible policies to encourage the cost-effective deployment of energy storage systems, including refinement of existing procurement methods to properly value energy storage systems.

In October 2013, the CPUC adopted an energy storage procurement framework and established an energy storage target of 1,325 megawatts for PG&E, Edison, and SDG&E by 2020, with installations required no later than the end of 2024.

            → Read the press release

 

As required by D.13-10-040, on February 28, 2015, the three Investor Owned Utilities (IOUs) - PG&E, SCE and SDG&E, filed their Energy Storage (ES) Application containing a proposal for the first ES procurement period (2014-2016).

 

On October 16, 2014, the CPUC approved the ES Applications with modifications in D.14-10-045.

 

The IOUs will file their Applications with final ES request for offer (RFO) results for CPUC approval by December 1, 2015.

Events

  • The goal of the California Public Utilities Commission Rule 21 Interconnection Proceeding is to promote timely, non-discriminatory, cost-effectively, transparent interconnection of new facilities to the grid. (Order Instituting Rulemaking, 11-09-011, Sept. 27, 2011.)  The CPUC determined, in R.10-12-007, that appropriate interconnection policies are one of the major barriers toward the deployment of storage.  (R. 10-12-007 Energy Storage Phase 2 Interim Staff Report – January 13, 2014.)

    Energy Division staff has issued a document proposing Issues, Priorities and Recommendations for the Interconnection of Energy Storage in the interconnection proceeding in order to develop the record on this topic.

    The staff proposal was entered into the Interconnection Proceeding by a Ruling issued July 29, 2014. The Ruling set a schedule for comments and reply comments and also calendared a prehearing conference on the document.
     

    Parties to the Interconnection Proceeding may submit Comments by September 12 and Reply Comments by September 26.  The Prehearing Conference on the document is set for October 2, 2014 at 10 a.m.

    For information on becoming a party to the Interconnection Proceeding or submitting comments, please contact the CPUC Public Advisor.
