MidAmerican Energy Rate LS — EV fast-charging electricity cost
MidAmerican Rate LS is the filed rate schedule ForgeAsset models for DC fast-charging sites in MidAmerican Energy territory in Iowa. Energy prices at 6.3¢/kWh flat; the demand side bills $6.74/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 21.2¢/kWh per dispensed kWh — rank 15 of 86 filed tariffs (1 = least expensive).

MidAmerican's large-service rate across most Iowa metros: cheap flat energy — the tariff's first pricing block covers a charging site's whole monthly volume — against a light demand charge on the monthly peak with no ratchet and no time window. Figures fold the fuel, efficiency, and transmission riders, a filed annual credit, and Des Moines' combined 13.95% sales-and-franchise stack; Iowa City and Coralville run lower. Iowa's 2.6¢/kWh electric-fuel excise is carried separately in the state tax profile.

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 15 of 86.
The rest of the Iowa picture
The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in Iowa covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.
MidAmerican Energy Rate LS — questions
- What does MidAmerican Energy charge for energy on Rate LS?
- The modeled rates are 6.3¢/kWh flat. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 6.3¢/kWh.
- Does Rate LS carry a demand charge?
- Yes: $6.74/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $8,086 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 21.2¢/kWh per dispensed kWh, rank 15 of 86 tariffs in the library (1 = least expensive).
