We Energies Cg 3 — EV fast-charging electricity cost
We Energies Cg 3 is the filed rate schedule ForgeAsset models for DC fast-charging sites in We Energies territory in Wisconsin. Energy prices at 6.7¢/kWh–23.8¢/kWh by time of day; the demand side bills $12.28/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 39.1¢/kWh per dispensed kWh — rank 47 of 86 filed tariffs (1 = least expensive).
Modeled rates
| Peak energy | 23.8¢/kWh |
| Off-peak energy | 6.7¢/kWh |
| Super-off-peak energy | 6.7¢/kWh |
| Demand | $12.28/kW of monthly peak |
| Rates effective | 2026-01-01 |
We Energies' Milwaukee-area secondary demand rate: an expensive 9 a.m.–9 p.m. weekday on-peak energy price against a moderate demand charge, after the tariff's hours-use mechanism is decomposed exactly into those two parts at charging-site load factors. Figures fold Milwaukee's 7.9% combined sales taxes. Wisconsin's 3¢/kWh charging excise is carried separately in the state tax profile. A rate case filed April 2026 re-bases these figures around January 2027.

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 47 of 86.
The rest of the Wisconsin picture
The tariff is one layer. State taxes, incentives, clean-fuels programs, and the charging market shape the remainder — Tesla Supercharger ROI in Wisconsin covers them, and the US Supercharger Economics Map shows every US Supercharger over utility territories colored by this same effective-cost derivation.
We Energies Cg 3 — questions
- What does We Energies charge for energy on Cg 3?
- The modeled rates are 6.7¢/kWh–23.8¢/kWh by time of day. At the model's default time-of-use mix (30% peak, 45% off-peak, 25% super-off-peak) that blends to 11.9¢/kWh.
- Does Cg 3 carry a demand charge?
- Yes: $12.28/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $14,740 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 39.1¢/kWh per dispensed kWh, rank 47 of 86 tariffs in the library (1 = least expensive).
