Negative Electric Vehicle Emissions: Vehicle-to-Grid Can Incentivize Enough Wind and Solar Investment to Reverse EV Charging Emissions.

ABSTRACT: Consequential emission analyses of power system interventions typically overlook induced structural changes. We estimate the consequential power system emission effects of plug-in electric vehicle (PEV) charging due to both operational effects and induced renewable capacity investments. We study PJM, the largest U.S. grid operator, with a grid mix representative of North America, assuming 10% fleet electrification. We find that charging immediately after each day's final trip increases grid emission externalities and provides little incentive to increase renewable infrastructure investment. In contrast, flexible cost-minimizing charging creates economic incentives to increase wind and solar capacity investment by 4% for unidirectional charging or by 23% for bidirectional vehicle-to-grid (V
