Utility Experience with Vehicle-to-Grid Regulatory and Technology Challenges, and the Final Hurdles to Large-Scale V2G Deployment

Advancements in electric vehicle charging equipment, vehicle battery improvements, and technical standards updates have led to a recent proliferation of vehicle-to-grid (V2G) demonstration projects that presages a dramatic increase in V2G deployments worldwide. This paper discusses one utility's initial experiences in developing a regulatory framework for customer participation in V2G. It also covers the technical barriers encountered when implementing several V2G demonstration projects, and considers the final barriers that remain before V2G chargers are widely installed across the power system.
