Independent power producer Clearway Energy Group has brought a 36MW solar PV plus 144MWh battery energy storage system project online in O’ahu, Hawaii, delivered by energy technology firm Wärtsilä.

AES Waikoloa solar PV and battery storage project on Hawaii Island is nearing completion.

Energy project integrator Ameresco and utility Bright Canyon Energy have broken ground on a solar and storage project with a 168MWh battery system at the Joint Base Pearl Harbor-Hickam West Loch Annex in Hawaii.

Clearway Energy Group has brought online the first ever utility-scale solar-plus-storage project on the Hawaiian island of O’ahu.

Construction has begun on two large-scale solar projects paired with battery storage in Hawaii from AES Corporation.

Energy technology company Wärtsilä is supplying 500MW/2,000MWh of battery energy storage systems (BESS) to PV projects operated by Clearway Energy Group in Hawaii and California, US.

A large-scale solar PV plant with four-hour duration battery storage could be built on underutilised land at a US Armed Forces Base in Hawaii.

Utility Hawaiian Electric has launched a 10-year programme of credits and incentives to its Battery Bonus scheme, which launched last year as a one-time cash incentive for adding battery storage to residential PV systems.

US$219 million of financing has been secured by developer Plus Power for the 185MW / 565MWh Kapolei Energy Storage (KES) project in O’ahu, Hawaii. 

Two pumped hydro energy storage (PHES) projects at very different stages of development in Hawaii and Wyoming would enable hundreds of additional megawatt-hours of clean energy use in each region.
