Vehicle-Grid Integration Activities
The CPUC has addressed vehicle-grid integration through a December 2020 “Decision Concerning Implementation of Senate Bill 676 and Vehicle-Grid Integration (VGI) Strategies” or Decision (D.) D.20-12-029. The August 2020 CPUC Energy Division VGI staff paper asks for comments (on a number of questions and/or identified potential venues regarding recommendations from the June 2020 VGI Working Group final report.
The Decision ordered three workshops:
- Energy Division staff hosted a January 2020 workshop on Automatic Load Management
- California IOUs hosted a March 2020 workshops on potential SB 676 VGI pilots and a March 2020 workshop on increasing EV participation in demand response programs.
As required by D.20-12-029 the California IOUs have released:
- VGI Pilots Stocktake March 2021
- VGI SB 676 Reporting Template Apr 2021
- VGI/demand response workshop report May 2021
- IOUs report with load profiles related to SB 676/VGI and cost data-March 2021
- PG&E, SCE, and SDG&E released their first interim VGI reports on September 15, 2021
(R.18-12-006), a new 2019 VGI Working Group will answer at a minimum:
- What VGI use cases can provide value now, and how can that value be captured?
- What policies need to be changed or adopted to allow additional use cases to be deployed in the future?
- How does the value of VGI use cases compare to other storage or Distributed Energy Resources?
Below are the VGI pilots proposed by the IOUs
- PG&E-VGI Pilot-Advice Letter 6259-E
- PG&E provided additional information in an October 15, 2021 Data Response to Energy Division staff and budget spreadsheet.
- In response, the CPUC released Draft Comment Resolution E-5192 on March 3, 2022. The draft resolution would, if adopted by the CPUC, approve three of PG&E's proposed pilots. The CPUC also provided instruction on providing public comments by March 23.
