Powin Energy will provide 2.4MWh of energy storage systems across seven sites in Hawaii.

The seven solar-plus-storage projects are being built by Adon Renewables. They will use Powin’s Energy Stack140 battery units plus the company’s Battery Pack Operating System (bp-OS) management software.

All seven will look to exploit Hawaii’s high peak electricity prices by shifting the solar system’s daytime generation to evening uses.

“Hawaii is a very important market for energy storage because of the state’s aggressive goal to run on 100% renewable energy by 2045, so we’re pleased to have built this partnership with Adon Renewables and secured the first of what we hope to be many projects with them on the islands,” said Geoffrey Brown, president, Powin Energy.

“The state has already installed a large amount of solar both residentially and commercially, but all of these distributed resources have created an urgent need for energy storage to maintain system frequency and voltage as well as energy shifting from daytime to peak periods in the evening when it is needed most,” added Brown.

Adon Renewables president Michael Chen cited Powin’s battery management software as a decisive factor in the company’s selection for the projects, which include a Boy Scouts of America property and the Aqua Kauai Beach Resort.

Hawaii is tipped as an important future market for energy storage with connectivity issues common for all islands, good solar penetration, favourable policy and high electricity rates.
