Green Mountain Power: current charging tariff not used

No current calculator-ready Green Mountain Power tariff resolves safely on 2026-10-01. CalcuRiver uses the Vermont EIA residential average for the visible fallback and does not present it as a Green Mountain Power rate.

What is being calculated?

Vehicle efficiency3.32 mi/kWh

Utility referencestate average fallback

Battery referencenot published in verified set

MPGe-backed vehicles use the EPA 33.7 kWh/gallon-equivalent conversion; EPA says the MPGe label value already includes charging losses, so CalcuRiver does not add another default loss. Where a manufacturer source gives usable battery and EPA-estimated range but not MPGe, the reference efficiency is battery ÷ range and a 10% wall-loss assumption is applied by default.
