Influx of Electric Vehicles Accelerates Need for Grid Planning

A new PNNL report says the western U.S. bulk power system can reliably support projected growth of up to 24 million electric vehicles through 2028, but challenges will arise as EV adoption grows beyond that threshold. This study is the most comprehensive of its kind, integrating multiple variables not evaluated before, such as growth in commercial delivery fleets and long-haul trucks, as well as large-scale and long-term EV charging scenarios and strategies.
