The District of Columbia Public Service Commission has granted in part and denied in part an application of the Potomac Electric Power Company (PEPCO) for approval of its transportation electrification program. Specifically, the commission: (1) approved the development of Residential Whole House Time-Of-Use Rate for electric vehicles; (2) directed PEPCO to provide “make-ready” infrastructure for public electric vehicle (EV) charging and public transportation charging to facilitate the deployment of public electric vehicle charging stations; (3) determined that PEPCO can only sell electricity from an EV charging station through an affiliate; and (4) established a temporary Transportation Electrification (TE) Working Group to further explore and develop offerings for a fixed price residential rebate and multi-dwelling unit EVCS deployment.
PEPCO had proposed that the costs of the residential offerings would be collected from all residential ratepayers, while the costs of the commercial offering would be allocated to commercial customers. The commission said that while it recognizes that the utility will seek cost recovery for all prudently incurred costs related to the approved tariff offerings, its plan to “socialize costs broadly” is likely not appropriate. Accordingly, it authorized PEPCO to establish a regulatory asset to track EV expenditures for the “make-ready” investments related to the approved offerings and for the coordination/management expenses such as billing, customer enrollment and outreach, program management, system interface and updates, analysis and reporting.
