Xcel Energy (South Dakota) General Service — EV fast-charging electricity cost

Xcel Energy SD General Service is the filed rate schedule ForgeAsset models for DC fast-charging sites in Xcel Energy territory in South Dakota. Energy prices at 28.5¢/kWh flat; the demand side bills none (energy-only). For one reference Supercharger site held constant across the whole library, that works out to 32.0¢/kWh per dispensed kWh — rank 41 of 86 filed tariffs (1 = least expensive).

Modeled rates

Xcel's South Dakota general-service schedule caps billing demand at monthly energy divided by 75 hours — at fast-charging utilization the cap binds and the entire demand charge folds exactly into the energy rate. The bundled figure carries the fuel and rider stack plus the 6.2% Sioux Falls tax fold, on compliance rates fresh as of July 2026 with a base-rate moratorium through 2029. Where utilization exceeded the cap's envelope the folded rate overstates rather than understates. The state sales-tax component steps to 4.5% in mid-2027 under enacted law.

What the reference site pays here

Reference site: 8 Tesla V4 stalls at 235 kWh/stall/day (57,183 kWh dispensed per month), a 150kW per-stall demand assumption, the model's default time-of-use mix, and a 12% loss gross-up — identical to the full utility ranking, where this tariff sits at position 41 of 86.

The rest of the South Dakota picture

The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in South Dakota covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.
