AES Indiana Rate SL — EV fast-charging electricity cost

AES Indiana Rate SL is the filed rate schedule ForgeAsset models for DC fast-charging sites in AES Indiana territory in Indiana. Energy prices at 7.7¢/kWh flat; the demand side bills $26.47/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 64.2¢/kWh per dispensed kWh — rank 72 of 86 filed tariffs (1 = least expensive).

Modeled rates

AES Indiana's large secondary-service rate for Indianapolis: cheap flat energy against the heaviest demand charge in the covered set — about $26.47 per kilowatt-month after Indiana's 7% sales tax — billed on the average of the month's three highest 15-minute readings. The tariff's 60% trailing ratchet resolves to the current month for a site with a steady billed peak. A rate-case order issued June 2026 phases in about 3.7% across July 2026 and January 2027; the library re-derives when the new sheets post. No third-party EV-host schedule is filed in Indiana.

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. AES Indiana's EVX host tariff closed in 2024.

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 72 of 86.

The rest of the Indiana picture

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

AES Indiana Rate SL — questions

What does AES Indiana charge for energy on Rate SL?

The modeled rates are 7.7¢/kWh flat. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 7.7¢/kWh.

Does Rate SL carry a demand charge?

Yes: $26.47/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $31,766 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 64.2¢/kWh per dispensed kWh, rank 72 of 86 tariffs in the library (1 = least expensive).
