- Combined Cycle Cogeneration Plant
This 64-megawatt (MW) combined cycle cogeneration project near Honokaa, Hawai'i, was constructed by a joint venture of JA Jones Construction and Burns & McDonnell. The facility provides power for residents and businesses on Hawaii's Big Island. The plant is an independent power producer (IPP) that sells power to the island utility of Hawaii Electric Light Co. (HELCO), providing power to residents and businesses on the Big Island.
- Complete plant design
- Procurement support
- Complete substation and transmission line design
The project faced several hurdles: a tight schedule, with typical equipment shipment requiring 2 to 6 weeks; a shortage of qualified labor; staged construction requiring temporary simple cycle operation; and challenging geotechnical considerations. The site was on the side of a steep hill with underground voids from ancient lava flows.
