    In West Oahu, the island’s two main transmission corridors are linked together by transmission lines between power plants and substations. However, no similar connection exists on the eastern side of the island.

    The Hawaiian Electric Company Inc. (HECO), based in Oahu, Hawaii serves 95 percent of the state’s 1.2 million residents.
    HECO was looking for an answer to address overload and reliability concerns in this region and ensure reliable power supply to its customers.
