Ways To Save
We’ve put together a list of incentives* designed specifically for water and wastewater facilities. Custom rebates and technical assistance are also available for technologies or projects not listed on our forms.
*Incentives are available to all commercial electric utility ratepayers of Hawaii, Honolulu and Maui counties. They are available on a first-come, first-served basis and are subject to availability of funds, restrictions, and subject to change and/or discontinuation without advance notice.
Start planning for a newer, improved and more energy-efficient system. Potential improvements include installing variable frequency drives (VFDs) on motors, replacing pumps and motors with newer, high-efficiency models, and installing energy-efficient lighting at pump stations.
Lighting is one of the simplest and most effective ways to reduce energy use and should be one of the first areas assessed for potential projects. Consider upgrading to new, more efficient lamps in interior and exterior applications. You can also maximize your savings by installing occupancy sensors that turn off lights in seldom-trafficked areas.
HVAC can make up as much as one-third of the energy consumed in a typical building. Consider variable frequency drives for fans or an inverter variable refrigerant flow (IVRF) air conditioning system. Hawaii Energy’s incentives can help offset costs and help you make investments that reduce your energy consumption and lower your energy bills.
Do you have any other ideas? If a measure at your facility can contribute to energy savings but isn't listed here, you may qualify for additional custom incentives. Examples include: air compressors, process controls, high-speed blowers and grit removal. Contact Keith Block at or (808) 839-8880 as you begin the planning process so we can ensure you get the maximum incentives available.
