Green Mountain Power Rate 63/65 TOU — EV fast-charging electricity cost

Green Mountain Power 63/65 TOU is the filed rate schedule ForgeAsset models for DC fast-charging sites in Green Mountain Power territory in Vermont. Energy prices at 12.5¢/kWh–16.5¢/kWh by time of day; the demand side bills $30.06/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 78.4¢/kWh per dispensed kWh — rank 81 of 86 filed tariffs (1 = least expensive).

Modeled rates

Green Mountain Power's commercial and industrial time-of-use rate, mandatory above 200 kilowatts of demand and serving every Vermont Supercharger metro outside Burlington city limits. Demand is billed as two additive components — a peak rate on the maximum inside a sixteen-hour weekday window and a smaller rate on the maximum over all remaining hours — summed here into one per-kilowatt figure that cannot understate the bill. Figures fold the multiyear-rate-plan percent surcharges, the fuel gross receipts tax, and the 7% South Burlington sales tax; the statewide energy efficiency charge is a separate bill line not yet included, roughly five percent of a bill at this scale. A filed 7.5% rate change takes effect October 1, 2026, and re-derives this row.

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 81 of 86.

The rest of the Vermont picture

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

Green Mountain Power Rate 63/65 TOU — questions

What does Green Mountain Power charge for energy on Rate 63/65 TOU?

The modeled rates are 12.5¢/kWh–16.5¢/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 13.7¢/kWh.

Does Rate 63/65 TOU carry a demand charge?

Yes: $30.06/kW of monthly peak. For a reference 8-stall site at 150 kW per stall that comes to about $36,077 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 78.4¢/kWh per dispensed kWh, rank 81 of 86 tariffs in the library (1 = least expensive).
