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.
The contracts cover three sites in California and two in Hawaii, all being operated or developed by renewable energy developer Clearway. The projects are all four-hour systems at different stages of development, with two set to come online this year.
Wärtsilä will supply its GridSolv Quantum BESS solution which will be controlled by its energy management system (EMS), the GEMS Digital Energy Platform. Gridsolv uses lithium iron phosphate (LFP) batteries.
In California, Wärtsilä has started construction on BESS units totalling 275MW/1.1GWh to adjoin the Daggett 2 and Daggett 3 projects in San Bernadino, California. The two total 482MWac of PV and are adjacent to the site of a retired coal and natural gas plant. The orders were booked in Q3/Q4 2021 and will be completed in 2023.
“We’re very proud of these deals and our relationship with Clearway, which has recently chosen us for their largest projects,” Wärtsilä’s VP energy storage and optimisation Andy Tang told Energy-Storage.news.
“The California projects will be doing load shifting through merchant market participation and resource adequacy (RA),” he added.
