PEV Integration with Electrical Grid
Over time, many electric utilities have upgraded the electricity generation and distribution infrastructure to support increased electric load for air conditioning and other high-power loads. Electric vehicles could be the next major electric load for utilities to accommodate if deployment continues to expand nationwide. Integrating electric vehicles with the grid is a challenge for electric utilities. But utilities could also take advantage of the vehicles’ batteries for grid management.
To facilitate electric vehicle-grid integration, states have enacted policies to help utilities plan for the increased load, harness the potential grid benefits of electric vehicles, and ensure all customers can access home charging.
This map identifies which states have enabled notification to electric utilities of electric vehicle sales, have updated residential building codes to accommodate electric vehicle charging, and are piloting new technologies that enable electric vehicles to provide grid ancillary services (also known as vehicle-to-grid).
The PEV Dialogue Group recommends that states continue to protect the reliability of the electrical grid, minimize the cost of electric vehicle-grid integration, and treat electric vehicles similarly to other incremental electric loads.
