Electricity Laws and Incentives in Hawaii
The list below contains summaries of all Hawaii laws and incentives related to electricity.
Laws and Regulations
Alternative Fuel Standard Development
The state of Hawaii is responsible for facilitating the development of alternative fuels and supporting the attainment of a statewide alternative fuels standard. According to this standard, alternative fuels will provide 20% of highway fuel demand by 2020 and 30% by 2030. For the purposes of the alternative fuels standard, cellulosic ethanol is equivalent to 2.5 gallons of non-cellulosic ethanol.
(Reference Hawaii Revised Statutes 196-42)
Alternative Fuel Vehicle (AFV) Registration
Owners of electric vehicles and AFVs must pay an annual fee of $50, in addition to standard registration fees. Fees contribute to the State Highway Fund.
(Reference Hawaii Revised Statutes 249-31)
Alternative Fuel and Advanced Vehicle Acquisition and Rental Requirements
State agencies must coordinate vehicle acquisition efforts to transition light-duty state fleet vehicles to 100% zero emission vehicles (ZEVs) by 2035. To support the state fleet transition to ZEVs, state and county agencies must purchase light-duty vehicles that reduce petroleum consumption. Vehicle purchasing priority is as follows:
- ZEVs;
- Plug-in hybrid electric vehicles (PHEVs);
- Other alternative fuel vehicles; and
- Hybrid electric vehicles (HEVs).
Exemptions may apply. State agencies must purchase the most fuel-efficient vehicle available that meets agency needs, use alternative fuels and ethanol blended gasoline when available, evaluate a purchase preference for biodiesel blends, and promote the efficient operation of vehicles. For the purpose of this requirement, an alternative fuel is defined as an alcohol fuel, an alcohol fuel blend containing at least 85% alcohol, natural gas, liquefied petroleum gas (propane), hydrogen, biodiesel, a biodiesel blend containing at least 20% biodiesel, a fuel derived from biological materials, or electricity generated from off-board energy sources.
State employees renting a vehicle for government business must rent either EVs or HEVs. Rental rates for EVs and HEVs must be comparable to that of a conventional internal combustion engine vehicle equivalent.

Electric Vehicle (EV) Charging Station Policies for Multi-Family Residences
A multi-family residential dwelling or townhouse owner may install EV charging stations on or near a parking stall at the dwelling as long as the EV charging station is in compliance with applicable rules and specifications, the EV charging station is registered with the private entity within 30 days of installation, and the homeowner receives consent from the private entity if the EV charging station is placed in a common area. Private entities may adopt rules that restrict the placement and use of EV charging station but may not charge a fee for the placement. The EV charging station owner is responsible for any damages resulting from the installation, maintenance, repair, removal, or replacement of the EV charging station. A private entity includes associations of homeowners, community associations, condominium associations, cooperatives, or any nongovernmental entity with covenants.
A working group within the Hawaii Department of Business, Economic Development, and Tourism identified and examined the issues regarding multi-family dwelling EV charging station requests to private entities. The group reported its findings and recommendations to the state legislature in December 2015.
(Reference Hawaii Revised Statutes 196-7.5)
Electric Vehicle (EV) Charging Station Rebate Program Authorization
The Hawaii Public Utility Commission (PUC) is authorized to establish an EV charging station rebate program. The PUC may contract with a third-party, non-government entity to administer, operate, and manage the rebate program. The PUC must prioritize rebate awards for EV charging stations that are publicly available; serve fuel cell electric vehicle fleets; serve multiple tenants, employees, or customers; support tourism; or serve low- or moderate-income or environmental justice communities. The Hawaii Legislature established a special fund within the PUC to support the EV Charging Station Rebate Program. The special fund receives $0.03 of the tax collected from each barrel of petroleum product sold by a distributor to any retail dealer or end user in Hawaii.
(Reference Hawaii Revised Statutes 243-3.5, 269-72 and 269-73)
Electric Vehicle (EV) Infrastructure Deployment Support
