Electric Vehicle-to-Grid Integration: From Concept to Reality

Key Points

• While vehicle-to-grid (V2G) integration remains more concept than reality in the U.S., it will likely afford economic value to cost-conscious utilities and their ratepayers in the long term.
• Although relatively few in number today, electric vehicles (EVs) are becoming less expensive, more convenient to drive, more abundant, and therefore meaningful as potential utility resources.
• Though it is small now, the U.S. market share of EVs is projected to grow rapidly beginning in the mid- to late-2020s.
• Automobile manufacturers, various electric utilities, and research institutions are working to address multiple technical and non-technical hurdles to EVs’ widespread integration with the grid.
• Once these hurdles are overcome, electric utilities across the U.S. will be able to build V2G systems incrementally, commensurate with their consumer demand, budgets, and system characteristics.
