Louisville Gas and Electric (LG&E) Rate TODS — EV fast-charging electricity cost

LG&E Rate TODS is the filed rate schedule ForgeAsset models for DC fast-charging sites in Louisville Gas and Electric territory in Kentucky. Energy prices at 4.5¢/kWh flat; the demand side bills $23.87/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 55.1¢/kWh per dispensed kWh — rank 66 of 86 filed tariffs (1 = least expensive).

Modeled rates

LG&E's time-of-day rate for the Louisville area: very cheap flat energy against a heavy per-kVA demand charge assembled from three nested time windows that each coincide with a charging site's peak. Figures fold the fuel and post-order riders and Kentucky's 6% electricity sales tax; the demand charge is billed on kilovolt-amperes, so a low power factor raises it slightly above the modeled kilowatt peak. Kentucky's 3.2¢/kWh charging excise and Louisville's local net-profits tax are carried separately in the state tax profile. Base rates are frozen through August 2028.

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.

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 66 of 86.

The rest of the Kentucky picture

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

Louisville Gas and Electric (LG&E) Rate TODS — questions

What does Louisville Gas and Electric (LG&E) charge for energy on Rate TODS?

The modeled rates are 4.5¢/kWh flat. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 4.5¢/kWh.

Does Rate TODS carry a demand charge?

Yes: $23.87/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $28,642 per month.

What does electricity cost per kWh dispensed on this tariff?

For the reference site — 8 Tesla V4 stalls dispensing 235 kWh per stall per day, with a 12% loss gross-up — the all-in utility cost works out to 55.1¢/kWh per dispensed kWh, rank 66 of 86 tariffs in the library (1 = least expensive).
