Verdigris Valley Electric Cooperative GSL — EV fast-charging electricity cost

Verdigris Valley GSL is the filed rate schedule ForgeAsset models for DC fast-charging sites in Verdigris Valley Electric Cooperative territory in Oklahoma. Energy prices at 5.4¢/kWh flat; the demand side bills none. For one reference Supercharger site held constant across the whole library, that works out to 6.1¢/kWh per dispensed kWh — rank 2 of 94 filed tariffs (1 = least expensive).

Modeled rates

Verdigris Valley Electric Cooperative's general service large rate for the suburbs north and east of Tulsa — Owasso, Collinsville-area parcels outside the city system, and Catoosa. Demand is billed per kilowatt of the monthly peak, and energy prices in declining blocks keyed to each month's energy per kilowatt of demand, which the model expresses as load-factor tiers; at fast-charging utilization all energy bills at the higher first-block rate. Rates fold Oklahoma's 4.5% state sales tax; city and county sales taxes vary by site and are not included. A power cost adjustment applies whenever the cooperative's actual power cost deviates from its 62.088-mill base, with no published factor, and the cooperative's rate summary states that a 2% gross receipts tax on revenue is included on bills — stated here rather than folded. No dated tariff sheet is posted; the rates date to March 2023 via the cooperative's newsletters and were unchanged in the August 2026 issue. Oklahoma tax defaults apply on address resolve.
