Utility Collaboration Forum Valuing Vehicle-Grid Integration Programs Report
This report examines how utilities, regulators, and industry stakeholders can assess and operationalize the value of VGI programs and services. Valuing VGI is fundamentally a grid planning exercise aimed at managing accelerating load growth while protecting customer affordability.
Utility Collaboration Forum Best Practices for Vehicle-Grid Integration Program and Pilot Development
The document provides essential guidance for utilities and regulators designing and implementing VGI initiatives, addressing a critical gap in existing literature and fostering consistency across North America.
V2X Bidirectional Charging Systems: Best Practices for Service Connection or Interconnection
The study considers two V2X bidirectional charging system use cases: equipment that requires (1) service connection for load and non-parallel operation, or (2) interconnection for parallel operation. Additionally, the best practices and recommendations outlined in this paper offer guidance to utilities and regulators for overcoming technical and process barriers to V2X bidirectional charging systems.
