With the closing of Oahu’s last coal-burning power plant less than two weeks in the rearview and a series of renewable energy goals on the advancing horizon, the new Kapolei Energy Storage facility in West Oahu is projected to both ease the transition from conventional power generation and serve as the backbone for the power grid of the future.


What You Need To Know

    • The 185 megawatt/565 megawatt hour battery storage project broke ground in April and is scheduled to be fully operational by May 2023
    • Located in an industrial area in Kapolei, KES is in proximity of a key Hawaiian Electric Co. substation
    • Once it is online, the facility will provide load shifting and fast-frequency response services to stabilize HECO’s electrical grid and allow it to immediately respond to fluctuations
  • Shaw said the facility will also help to limit curtailment, the intentional reduction of renewable energy output due to system constraints

Those are lofty visions for what at the moment looks like dozens of giant refrigerators lying on their sides in a 7-acre expanse of what, on a rainy September morning, is quickly turning into thick, shoe-sucking mud.
