Clearway Energy has withdrawn three hybrid solar and storage projects from Hawaiian Electric Co’s (HECO’s) latest renewable energy procurement, citing the investor-owned utility’s (IOU’s) “ongoing financial uncertainty”.

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.

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

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.

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).
