To support AEP Ohio’s program application to the Public Utilities Commission of Ohio (PUCO), in which the company sought to install 1300 electric vehicle charging stations over four years, E3 performed a cost-benefit analysis of plug-in electric vehicle (PEV) adoption in the company’s service territory. To do this, E3 developed a statewide PEV adoption forecast and estimated costs of PEVs and charging stations as well as the electric grid costs of serving PEV charging loads. E3 also quantified the benefits of PEV adoption, which primarily result from reduced gasoline and vehicle maintenance costs. E3’s analysis — which found net benefits of $1,600 per vehicle in Ohio, and utility ratepayer benefits of $1,470 per vehicle — provided credible, independent support for AEP Ohio witness testimony.
