Honolulu International Airport Distributed Generation Power Plant


In 2006, we assisted Hawaiian Electric Company in conducting a feasibility study for the State of Hawaii Department of Transportation-Airports Division to evaluate the technical, operational, and cost considerations for the potential installation of an emergency power facility at the Honolulu International Airport. This study also included the evaluation of the potential costs and operational considerations of HECO’s use of these units as dispatchable standby generators.

Following the completion of the study, we recently completed the design for a new 10 MW DG power plant for the Honolulu International Airport including Fuel Storage Tank Farm with Containment Berm, oil water separator, and truck unloading rack which will also accommodate a future expansion to 20 MW.

The current scope of work for the first phase of the generator building design includes providing four 2.5 MW Caterpillar diesel generators with radiators and associated auxiliary equipment, with the design fitting within the allocated site adjacent to HECO’s Airport substation. This entailed identifying setback and spacing requirements, ass well as maintaining the Department of Transportation easement. Also included in the scope was ensuring that the building design and construction would survive hurricane conditions, have a configuration considering noise abatement requirements, and allowing for access clearances required to deliver gen-sets to the site and fuel truck deliveries.

We also designed a 7-day usable fuel storage tank farm to allow for future fuels (naptha, diesel/ethanol, or jet fuel). The fuel tank and foundation are designed in accordance with API 650 with El Segundo leak detection tank bottom, fuel containment wall, containment area lining for spill containment.
