    • Custom Field-Erected Fuel Tanks

    • Generator Engine Exhaust System

    • Distributed Power Generation

  • • Automated electric power

    • Monitoring, and distribution system allows for remote dispatch by HECO

    • Multi-story building design developed to fit within the available footprint

    • Sound attenuation silencers incorporated into the design to meet city and state noise limits.

    • Fuel system designed to use environmentally-friendly biodiesel fuel

Hawaiian Electric Company (HECO) and the Department of Transportation Airports Division (DOTA) each faced engineering challenges. HECO needed a solution to strengthen their electrical grid during peak demand periods, while DOTA aimed to construct a consolidated facility to provide emergency power to the Daniel K. Inouye International Airport.

As the prime consultant, InSynergy Engineering, Inc. developed engineering concept sketches for potential sites and evaluated their feasibility. Ultimately, a site near HECO’s existing electrical substation serving the airport was chosen for the construction of a multi-story emergency power generation facility. Our team provided mechanical, electrical, and fire protection design, as well as project management. This facility can supply up to 80% of the airport’s electrical demand during emergencies. In non-emergency periods, it supplements HECO’s electrical grids by providing up to 8MW of power with a single click from a remote dispatch location.

The building features four 2.5MW prime power-rated emergency generators, an intake and discharge air system, and an engine exhaust system meeting strict EPA emissions standards. Additionally, the fuel storage and delivery system includes two custom-built steel tanks capable of keeping the airport operational for at least 96 hours. Notably, the entire fuel system is designed to support biodiesel fuel. Furthermore, a sophisticated generator master control system automatically monitors power demands from over 10 electrical vaults throughout the airport, supplying emergency power based on priority demands identified by DOTA.

  • first of its kind shared photovoltaic (PV) system with battery energy storage,

  • gas for cooking, backup water heating and power generation,

  • a grid electricity tie for the battery trickle charging.

The integrated microgrid system design includes full mechanical, plumbing and electrical systems, as well as 1956 kw of PV, a 1.965 MWH BESS, and a 300 kw standby LPG generator. Completed in 2018, this innovative projects includes the implementation of a reliable and failsafe microgrid control system that accommodates all potential modes of operation due to a lack of proven off-the-shelf solutions. In addition, it utilizes larger, lower cost inverters that serve multiple housing units and distributed sewer lift stations, and uses three-phased balanced power distribution within housing units.

This project was awarded a 2019 ACECH Engineering Excellence Design Award.

The Queen's Medical Center

HONOLULU, HAWAII

In order to accommodate the growing need for emergency healthcare services, the Queen’s Medical Center took action by authorizing the design and construction of a new $10,000,000 emergency services ward.  The emergency services relocation involved renovating 25,000 sf of existing office space into an emergency ward which included fully equipped critical and trauma rooms, exam rooms, fast track triage area, a psychological disorder ward, dedicated infectious isolation rooms and waiting areas, and nursing stations.

As part of their ongoing facility improvement program, we recently designed the renovation of their entire chiller plant which included replacing two 1,000-ton chillers with two 1,350-ton high efficiency chillers, each equipped with VFD compressors.  A major system re-engineering was implemented to convert the old primary constant-flow chill water distribution loop to a new primary secondary variable flow chill water loop.  This conversion allowed the central plant to increase or decrease chill water flow based on actual cooling requirements.  These renovations resulted in an annual energy savings of $180,500.

Other renovation projects include:

  • OR Upgrade and Renovation, Queen Emma Tower, 3rd Floor

  • Replace Boiler Plant

  • New Linear Accelerator

  • Renovation of the air conditioning system for the main lobby

  • Hot Water Study for POB 1, POB 2 & Central Plant

  • Pauahi Tower Service Elevator Upgrade

  • Renovation of Iolani 1 and Kinau 1

  • Iolani 2 and 3 Renovation

  • New MRI Unit Addition

  • Diagnostics Lab, 4th Floor, Nalani Wing

  • Grease Interceptor Study
