Box San Francisco, CA Fax: August 1, 2017 Advice 5119-E (Pacific Gas and Electric Company U 39 E) Advice 3640-E (Southern California Edison Company U 338 E) Advice 3103-E (San Diego Gas & Electric Company U 902 E) Public Utilities Commission of the State of California Subject: Update to Community Choice Aggregate and Energy Service Provider Load Data and Utility Investment and Procurement Information Purpose Pursuant to Ordering Paragraph (OP) 5 of California Public Utilities Commission (CPUC or Commission) Decision (D.) , Pacific Gas and Electric Company (PG&E), on behalf of Southern California Edison (SCE), and San Diego Gas and Electric (SDG&E), respectfully submits this advice letter to update Tables 3 through 6 based on the most current Community Choice Aggregator (CCA) and Energy Service Provider (ESP) load data and utility investment and procurement information. Background On October 21, 2013, the Commission issued D to establish the Energy Storage Procurement Framework and Design Program ( Energy Storage Program ). The Energy Storage Program set a procurement target of 1,325 megawatts of energy storage projects for the Investor-Owned Utilities ( IOU ) to procure through a series of solicitations from 2014 to All storage projects must be online no later than Additionally, the Energy Storage Program set a procurement target for all CCAs and ESPs to procure one percent of their 2020 load, with all storage projects being online 1 D , Appendix A, p.1 2 Ibid.

6 Advice 5119-E, et al August 1, 2017 no later than As determined by the Commission, the one percent procurement target for CCAs and ESPs is in addition to paying for a portion of IOU storage procurement via non-bypassable charges. 4 On January 5, 2016, the CPUC issued a Scoping Memo and Ruling in Track 2 of the Energy Storage Order Instituting Rulemaking (OIR) seeking parties comments on revision of energy storage procurement targets. 5 The Alliance for Retail Energy Markets and Direct Access Customer Coalition (AReM/DACC) argued that some CCA/ESP procurement obligations can exceed a utility s, and proposed to prohibit future cost recovery through non-bypassable charges and credit ESPs with any excess storage for procurement that is above what the IOUs are obligated to procure. 6 In D , the Commission ruled that revisions to cost recovery of storage procurement were beyond the scope of the proceedings, but that it was in scope to consider revisions to the CCA/ESP storage procurement targets. The Commission reviewed the extent to which the combined one percent procurement obligation and non-bypassable charges assigned to CCAs/ESPs compares with the utility procurement obligations, as a percentage of utility load. In the instance that a CCA/ESP procurement obligation exceeds that of the utility, the Commission adopted an automatic limiter that proportionately reduces each CCA/ESP one percent procurement obligation by the amount the load serving entity s procurement plus its customers share of non-bypassable charges exceeds the utility obligation by a percentage of load. 7 Comparing IOU and CCA/ESP storage procurement obligations as a percentage of load is done using Tables 3 through 6 of D D requires the IOUs to update Tables 3 through 6 on an annual basis beginning August 1, 2017 through The updated tables are provided. 3 D , p Ibid. 5 R Assigned Commissioner and Assigned Administrative Law Judge s Scoping Memo and Ruling Seeking Party Comments, p D , p D , p.27.

Storage projects resulting from the biennial storage solicitations have not yet come on-line, so their above market costs have not been identified, and PCIA costs have not yet been allocated to nonutility Load Serving Entities (LSEs). We do not include a requirement of a forecast of nonbypassable charges as suggested by CCA Parties in comments on the Proposed Decision as we find this too speculative and of limited value. 9 6 MW via distribution charge + 10 MW of customer-sited SGIP/PLS projects (R : Motion of PG&E to Further Update Information in its January 4, 2016 Report Regarding Energy Storage System Procurement Targets and Policies - July 7, 2017), and 0.5 MW for Browns Valley (A ; D ) MW via distribution charge MW of SGIP/PLS + 22 MW of Aliso Canyon Energy Storage (ACES) projects (Resolution E MW of original 27 MW authorization was cancelled) MW in West LA Basin via SCE 2013 LCR RFO to replace SONGs capacity (D ) MW via distribution rates MW of SGIP/PLS (D , Attach A) MW of ACES storage projects (Resolution E-4798) MW ACES Design Build Transfer project (Resolution E-4791) + Preferred Resources Pilot 2-60 MW (A ) MW (A LCR RFO Moorpark) + 20 MW ACES EGTs (A ) 13 A June 2017 data, available at Supplemental Direct Access Implementation Activities Report Statewide Summary June 15, Direct Access (DA) ESPs are responsible for non-bypassable charges based on load share for CAM and distribution rates.
