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.
