Pepco (District of Columbia) GT LV + SOS — EV fast-charging electricity cost

Pepco DC GT LV + SOS is the filed rate schedule ForgeAsset models for DC fast-charging sites in Pepco territory in District of Columbia. Energy prices at 19.6¢/kWh–20.2¢/kWh by time of day; the demand side bills $31.09/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 87.4¢/kWh per dispensed kWh — rank 83 of 86 filed tariffs (1 = least expensive).

Modeled rates

Pepco's District of Columbia large general service rate with standard offer service supply: filed fixed seasonal time-of-use supply strips cover the entire large-commercial ladder — the Pepco DC book contains no hourly-priced service — against Rate Year 2 delivery. The demand figure folds the maximum-demand and transmission components plus a month-weighted summer noon–8 p.m. window component. The supply strip resets each June; a remand of the delivery rate case is pending with no 2027 delivery rates filed, which sets a mandatory re-derive, and two surcharge levels step on 2026-10-01.

The filed rate book for this territory records no EV-specific commercial rate, so the modeled cost is the standard schedule. Demand follows the model's conservative convention — 150 kW per stall billed every month, the worst-case coincident peak — so a site whose metered peak runs below that would see a lower demand line.
