Maui Electric (Hawaiian Electric, Maui County) Schedule P — EV fast-charging electricity cost

Maui Electric Schedule P is the filed rate schedule ForgeAsset models for DC fast-charging sites in Maui Electric territory in Hawaii. Energy prices at 38.0¢/kWh flat; the demand side bills $29.44/kW of monthly peak. For one reference Supercharger site held constant across the whole library, that works out to 104.4¢/kWh per dispensed kWh — rank 85 of 86 filed tariffs (1 = least expensive).

Modeled rates

Maui Electric's large power schedule: the same design as Oahu's with Maui's own fuel clause and a 17.77% revenue balancing adjustment, a 200-kilowatt billing floor, and the same inert mean-form demand ratchet; taxes are embedded in the filed rates. The energy cost recovery clause resets monthly, the fastest-moving component in the library.

The utility files an EV-specific rate or pilot that this model does not assume, so the modeled electricity cost reflects the standard schedule. A site that qualified for and enrolled in that program would see a lower demand line than the one modeled here. Maui Electric files the same Schedule EV-P pilot — capped at 500 accounts and sunsetting in March 2027, inside this model's 15-year horizon.

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 85 of 86.

The rest of the Hawaii picture

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