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. 

ENGIE will no longer proceed with a grid-scale solar-plus-storage project it was awarded in Hawaii, cancelling its order for 240MWh of battery storage from technology provider New HOrizons Ahead (NHOA). 

Hawaiian Electric is launching its newest “all-source” renewable energy procurement for capacity and grid services on the eastern side of Hawaii Island.

News in brief from around the world in energy storage.

Supply chain disruptions caused by the COVID-19 pandemic hit Canada-headquartered residential and small commercial battery storage company Eguana Technologies’ sales figures hard, the company has said. 

After the expansion of the biggest battery project in world, milestones have been recorded for three more major solar-plus-storage and standalone battery storage projects in California, Hawaii and Florida.
