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.) 17-04-039, 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.13-10-040 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 2020.1 All storage projects must be online no later than
2024.2
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

Advice 5119-E, et al. -2- August 1, 2017 no later than 2024.3 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.17-04-039, 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.17-04-039. D.17-04-039 requires the IOUs to update Tables 3 through 6 on an annual basis beginning August 1, 2017 through 2020. The updated tables are provided. 3 4 5 6 7 D.13-10-040, p. 46 Ibid.

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. 6 MW via distribution charge + 10 MW of customer-sited SGIP/PLS projects (R.15-03-011: 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.16-03-001; D.16-09-007). 13.92 MW via distribution charge + 17.4 MW of SGIP/PLS + 22 MW of Aliso Canyon Energy Storage (ACES) projects (Resolution E-4804 - 5 MW of original 27 MW authorization was cancelled) + 263.64 MW in West LA Basin via SCE 2013 LCR RFO to replace SONGs capacity (D.15-11-041). 6.15 MW via distribution rates + 10.02 MW of SGIP/PLS (D.14-10-045, Attach A) + 37.5 MW of ACES storage projects (Resolution E-4798). 20 MW ACES Design Build Transfer project (Resolution E-4791) + Preferred Resources Pilot 2 - 60 MW (A.16-11-002) + 0.5 MW (A.14-11-016 - 2013 LCR RFO – Moorpark) + 20 MW ACES EGTs (A.17-03-020) A.17-04-017 June 2017 data, available at http://www.cpuc.ca.gov/General.aspx?id=6598. Supplemental Direct Access Implementation Activities Report – Statewide Summary – June 15, 2017. Direct Access (DA) ESPs are responsible for non-bypassable charges based on load share for CAM and distribution rates. This does not include PCIA for storage. ESPs comprise 13.0 percent of load share, based on the latest Direct Access Implementation Activities Report, published June 15, 2017, accessible at: http://www.cpuc.ca.gov/General/aspx?id=6598
