This brief lays out the challenges and opportunities of vehicle-grid integration (VGI). Electric vehicles (EVs) can help increase the utilization of existing electrical grid assets and put downward pressure on electricity rates by decreasing the average cost of delivering electricity. Many aspects of VGI, including time-of-use (TOU) rates and demand response programs have similar characteristics to other grid management programs. As mobile energy storage systems, EVs also present unique challenges to grid integration. When applied effectively, VGI programs can minimize the impact of EVs on the distribution grid and lead to a more resilient and reliable power grid.
