Hawaiian Electric Co. proposes new energy storage projects

Hawaiian Electric Co. is planning a pair of new energy storage projects, which will total 120 MW in capacity.

A 20 MW project worth $43.5 million will be linked to a solar power array at the West Loch Naval Annex. Construction may begin at October 2019 with commercial operation at February 2020, according to HECO.

Another energy storage project, to be built at Hawaiian Electric’s Campbell Industrial Park Generating Station, will have a 100 MW capacity. This project will act as a reserve on the Oahu power grid and will start construction October 2019 and come online a year later.

Hawaii’s state public utilities commission will have to approve both projects.
