As part of her work facilitating the technical group of the Alaska Electric Vehicle Working Group, organized by the Alaska Energy Authority, Michelle Wilber of ACEP developed an Excel calculator for the electrical costs of charging electric vehicles.

A user of this calculator can use preset electricity rate data for Alaska road system utilities (valid as of January 2020), or input custom rates, including energy and demand charges, as well as EV charger utilization and power use of the charger to calculate the addition to a monthly electric bill.

The calculator also shows the cost per hour of charging, the cost per 50kWh "fill-up," the electricity costs per mile of driving, and a comparison with an internal combustion vehicle. Individuals contemplating an electric vehicle purchase, or potential site host considering installing charging infrastructure can use this calculator to investigate the economics.
