Hawaii gives green light to 185MW storage plan

S&P Global Market Intelligence ($):

As part Hawaii’s bid to wean itself completely off fossil fuel-fired power, state regulators approved Hawaiian Electric Co. Inc.’s 20-year power purchase agreement with an affiliate of San Francisco-based developer Plus Power for its 185-MW/565-MWh Kapolei Energy Storage Project in an industrial corner of Honolulu County.

The Hawaiian Electric Industries Inc. utility subsidiary pitched the contract in September 2020 as part of a package of solar farms and energy storage projects on the island of Oahu to help plug a power gap with the planned retirement in 2022 of its only coal-fired resource, AES Corp.’s 180-MW AES Hawaii facility.

The energy storage project is the biggest lithium-ion battery station Hawaii has approved to date, according to S&P Global Market Intelligence data. It is intended to initially provide load shifting and fast frequency response.
