3. Agenda for the Workshop

4. Workshop Purpose and Goals To establish a record for decision making in R.10-12-007 to satisfy the terms of AB 2514 (PUC Section 2836) with regard to establishing potential energy storage procurement targets for load-serving entities (LSEs).

5. Workshop Purpose and Goals Responsive to AB 2514, which requires the CPUC: • To open a proceeding to determine appropriate targets, if any, for each load-serving entity to procure viable and cost-effective energy storage systems. • By October 1, 2013, to adopt energy storage procurement targets, if determined to be appropriate, to be achieved by each LSE by December 31, 2015, and a 2nd target to be achieved by December 31, 2020. • 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.

6. Evaluation of Procurement Targets AB 2514 specifically requires that the CPUC: (a) Consider existing operational data and results of testing and trial pilot projects from existing energy storage facilities. (b) Consider available information from the California Independent System Operator testing and evaluation procedures. (c) Consider the integration of energy storage technologies with demand-side management or other means of ensuring the most efficient use of generation resources and cost-effective energy efficient grid integration and management. (d) Ensure that the energy storage system procurement targets and policies that are established are technologically viable and cost effective.

8. Panel 1: Procurement Options • Janice Lin - Energy Storage Alliance • David Castle - Southern California Edison • Armando Infanzon - San Diego Gas & Electric • Daidipya Patwa - Pacific Gas and Electric

9. Procurement Options A) Procurement targets as a fixed percentage of load-serving entities’ load, may be structured as a capacity (Megawatt) threshold, or for specific applications for storage. B) Pilots or “Market Tests” focused on specific priority applications or end uses, to further develop tools for cost-effectiveness analysis. C) Portfolio - Setting aside a dynamically adjusted portion of procurement for need determination for “preferred” resources, specifically including storage. D) As noted by legislative analysis of AB 2514 he Commission’s determination could also result in a finding that no target level is appropriate. What additional information do we need to decide?

11. Panel 2: Operational Experience and Pilots • Jack Ellis, Independent Engineer and Consultant - Select Projects • Praveen Kathpal, AES Energy Storage – Lessons from the Field • Vic Romero, SDG&E Director – Asset Management & Smart Grid Projects – SDG&E Pilots

12. Energy Storage in EPIC plans • On November 1, 2012, the CEC, PG&E, SCE and SDG&E filed their required 2012-2014 Investment Plans for research & development programs funded via ratepayer contributions to the EPIC program. • Total $466.5 million for Applied Research, Technology & Demonstration (T&D), and Market Facilitation (2013-2016). • Utility spending is entirely in the T&D category. • As much as $60 million of the CEC project budget could be applied to energy storage research projects. Up to $15 million possible for IOU projects that could include storage.

13. Cost-Effectiveness Analysis Update Aloke Gupta, Regulatory Analyst, CPUC

14. Next Steps • Comments on this workshop may be incorporated with comments on January 4, 2013, Staff Interim Report and Use Cases. • Must be served to entire Service List for R. 10-12-007. • As per ALJ Ruling of January 10, 2013: • Comments are due February 4, 2013; • Response comments due February 21, 2013. • Ongoing work to conduct cost-effectiveness analysis.
