This report explores issues policymakers, especially state utility regulators, face in forming policy and regulation in this dynamic landscape of charging companies, aggregators, municipalities, utilities, and auto manufacturers, among others. Regulators are critical decision makers because of their ability to accelerate or slow EV deployment through policy decisions. They also have an important role to play to enable effective EV integration—both for accommodating new loads from EV charging onto the grid, and for ensuring reliability as new variable resources come online. In this report, we first describe the range of possible benefits that state utility regulators can enable from smart charging beyond simply minimizing impact on peak. We then describe the cases of two leading states—California and Washington—working to unlock the benefits of EVs. Although both California and Washington have addressed EV policy in some way, neither has comprehensively prepared for the arrival of EVs en masse and their potential impacts on the transportation and electricity systems.
