Electric Bus Facility

Hawaiian Electric's E-Bus pilot rates will enable bus fleet customers to benefit from lower prices that encourage charging during the Mid-Day period (9 AM – 5 PM) when there is abundant solar energy on the grid, and overnight during the Off-Peak period (10 PM – 9 AM) when electricity demand is low.

Putting more solar to use during the day by charging vehicles will also make room on the grid for new private rooftop solar systems as well as grid-scale renewable energy projects offering low-cost energy to all customers.

Demand charges typically paid by commercial customers are also eliminated during the Mid-Day and Off-Peak periods. These savings encourage operators to avoid the On-Peak period (5 PM – 10 PM) when there are higher rates and demand charges apply.


How to Enroll

We recommend contacting our Electrification of Transportation Department at GoEV@hawaiianelectric.com as early as possible in your planning process. A separate meter is required to enroll in this rate, and service upgrades may be needed depending on your facility and charging requirements.

If you are just getting started, the Edison Electric Institute's guide, “Preparing to Plug In Your Fleet: 10 Things to Consider” provides some helpful tips.

As part of the Volkswagen Settlement Environmental Mitigation Trust Agreement, the Hawaii State Energy Office proposed and received approval for the proposed allocation of trust funds:

  • $4.15 million, or 51 percent of Trust Funds, to projects which electrify Class 4-8 School Buses, Shuttle Buses, or Transit Buses (Environmental Mitigation Action #2)
  • $2.75 million, or 34 percent of Trust Funds, to projects eligible under the federal Diesel Emission Reduction Act grant program (Environmental Mitigation Action #10)
  • $1.22 million, or 15 percent of Trust Funds, to support projects which facilitate the deployment of Light Duty Zero Emission Vehicle Supply Equipment (Environmental Mitigation Action #9)

Visit the State Energy Office’s website for details or to join the VW mailing list for updates on upcoming funding assistance.

In addition, the U.S. EPA Diesel Emission Reduction Program has Clean Diesel National Grant opportunities and Clean School Bus Rebates.

Hawaii Energy is also administering electric vehicle charging station incentives funded by the State of Hawaii. First-time installation of new, multi-port, networked level 2 stations are eligible for $4,500 incentives. First-time installation of new, networked DC fast-charging stations are eligible for $35,000 incentives. Incentives are also available for retrofits. For more information, visit Hawaii Energy.
