Commonwealth Edison (ComEd) Watt-Hour EV class — EV fast-charging electricity cost

ComEd Watt-Hour EV class is the filed rate schedule ForgeAsset models for DC fast-charging sites in Commonwealth Edison territory in Illinois. Energy prices at 14.1¢/kWh flat; the demand side bills none (energy-only). For one reference Supercharger site held constant across the whole library, that works out to 15.8¢/kWh per dispensed kWh — rank 5 of 86 filed tariffs (1 = least expensive).

Modeled rates

ComEd's Watt-Hour delivery class, elected by separately metered EV charging sites of any size and guaranteed through at least September 2033: per-kWh delivery with no demand charge. The bundled rate folds delivery, riders, the Illinois electricity excise tax, and a supply component set to ComEd's published Price to Compare — a market benchmark standing in for a competitive fixed supply contract, which large accounts purchase from a retail supplier. The supply benchmark resets each June and October.

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 5 of 86.

The rest of the Illinois picture

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