This project was an off-grid development to house homeless families on O’ahu. Photonworks Engineering designed a microgrid to power a village of 153 housing units as well as community buildings consisting of preschools, daycare, laundry facility, management office, police station, community enter and sundry store. The system is sized to cover all the loads plus charge a central battery during daytime, and to deliver the stored battery power back to the residences and streetlights during night. The system has a backup propane generator for emergencies.
The microgrid model provides lower cost power along with added resiliency to the development. The residents all pay a flat rate for their utilities, and each house comes furnished with energy efficient fixtures. Cooling is provided by whole house fans in the residential homes and conventional air conditioning in the the community buildings. Solar water heaters with gas backup are in each home and the laundry facility.
In total, this project creates housing for over half of the State’s homeless families. By also providing jobs and on-site childcare, Kahauiki Village breaks the cycle of homelessness for the families who live there. We are extremely proud and grateful to have been part of this innovative project and will continue to deliver clean, dependable power for the rest of the Village’s operation.
