A 2019 Ruling of the California Public Utility Commission tasked a Working Group with addressing the following questions:
(a) What Vehicle-Grid Integration (VGI) use cases can provide value now, and how can that value be captured?
(b) What policies need to be changed or adopted to allow additional use cases to be deployed in the future?
(c) How does the value of VGI use cases compare to other storage or DER?
The VGI Working Group worked collaboratively between August 2019 and June 2020 to address these three questions. The report identified 320 different VGI use cases that should be considered as able to provide value by 2022. The Working Group developed a set of 92 individual recommendations for policy actions that California state agencies, utilities, community choice aggregators, and CAISO could undertake to advance VGI in the short-term (2020-2022), medium-term (2023-2025), and long-term (2026-2030).
