Energy Storage and Distributed Energy Storage ESDER Initiative
Energy Storage and Distributed Energy Storage (ESDER) Initiative California Independent System Operator CAISO – CPUC Energy Storage Workshop May 2, 2016 Tom Flynn, Storage and DER Policy Manager
Distribution connected resources are becoming an increasingly important part of the resource mix • Installed distributed solar PV – 3. 1 GW (U. S. EIA – Sep. 2015) – 3. 5 GW (California Energy Commission – Oct. 2015) – 3. 9 GW (Go Solar California – April 2016) • Forecasted distributed solar PV by 2026 – 9. 0 GW (CEC forecast) – 11. 6 GW (IOU forecasts) • Distributed energy storage by 2024 – 625 MW (CPUC procurement target) • Plug-in electric vehicles: 1. 5 million by 2025 (Governor’s goal) – 100, 000 PEVs sold in California (as of Aug. 2014) – 7, 687 PEV public charging outlets (as of Aug. 2015) Page 2
Integrating DER into CAISO markets will help lower carbon emissions and add operational flexibility • CAISO has developed models for DER to participate in its markets today – Demand Response (Proxy Demand Resource) – Non-Generator Resource (NGR) • CAISO is continuing to develop ways to enable DER – DER aggregation aka “DERP” (new structure enabling aggregated DER to participate in ISO market) – ESDER stakeholder initiative (Focus: Lower barriers and enhance ability of storage and DER to participate in CAISO markets) Page 3
ESDER Phase 1 stakeholder initiative • Topic areas 1. Enhancements to NGR model 2. Enhancements to demand response performance measures and statistical sampling 3. Clarifications to rules for non-RA multiple-use applications • Schedule – Launched in second quarter of 2015 – Provided forum for CAISO to follow-up on Energy Storage Roadmap – CAISO Board approved proposals on topics 1 and 2 – Stakeholder process to develop tariff amendments is underway Page 4
ESDER Phase 2 stakeholder initiative • Topic areas 1. Additional NGR enhancements 2. Additional demand response enhancements (ability to increase load consumption; develop alternative baselines) 3. Multiple-use applications (joint effort with CPUC) 4. Distinction between charging energy and station power (joint effort with CPUC) 5. Allocation of TAC to load served by DER • Schedule – March 22 Issue Paper – May 19 Straw Proposal (today’s workshop and May 13 comments will serve as additional input) – Targeting CAISO Board approval October 2016 Page 5
ESDER 2: Station power for energy storage devices • CAISO’s focus: Resolve the distinction between wholesale charging energy and station power • Topic of station power is inherently jurisdictional • Coordinating with R. 15 -03 -011 will economize staffing resources, avoid redundant efforts, and avoid conflicts • Today’s workshop, parties’ forthcoming comments, and the workshop report will help inform the CAISO’s proposals Page 6
