Maui Electric Company, Limited

Maui Electric does not offer a residential EV-specific time-of-use rate open to new customers in Maui County. Its general residential TOU options are closed: Schedule TOU-RI closed to new customers on October 31, 2022, and the Shift and Save TOU pilot closed to new enrollment on February 1, 2025. Residential EV owners therefore charge on their standard residential rate, which does not vary by time of day. Hawaii electricity prices are among the highest in the country, so households with rooftop solar can lower charging cost by charging during the day on their own generation.

There is no Maui Electric rebate for a home charger, so residential customers have no rebate to stack against a rate. On the commercial side, the Charge Up Commercial make-ready program covers the electrical infrastructure up to the charging equipment at eligible businesses, condominiums, office buildings, and fleet sites, though the utility is no longer accepting applications and is keeping a waitlist. Commercial charging on a dedicated meter can take service on the EV-J or EV-P time-of-use schedules, which reward mid-day charging.

Maui County spans three separate island grids (Maui, Lanai, and Molokai) with no interconnection to each other or the mainland, so charging load is balanced against locally generated solar and fossil generation rather than imported power. The commercial EV-J and EV-P pilot was extended by the Hawaii PUC through June 30, 2027, with the utility required to file successor tariffs by June 30, 2026. Hawaiian Electric, Hawaii Electric Light, and Maui Electric share program design under the Hawaii PUC, but enrollment and metering are handled by Maui Electric for each Maui County island.
