September 10 (Renewables Now) - Hawaiian Electric Company Inc earlier this week said it has submitted two energy storage projects it plans to develop on Hawaii island and Maui for approval by the Hawaii Public Utilities Commission (PUC).

The Hawaii Island project is for a 12-MW/12-MWh battery energy storage system (BESS) at the Keahole power plant, designed to provide fast frequency response to improve grid stability by helping avoid customer outages.

On Maui, the company is looking to develop a 40-MW/160-MWh BESS at a company-owned site in Waena, which will store energy during periods of low demand to discharge it during periods of peak demand.

The two self-build projects were part of the 16 projects announced as winners in May in the largest renewable energy procurement in the state of Hawaii. Proposals for the generation of 460 MW of solar power and close to 3 GWh of energy storage were selected back then.
