Wärtsilä and AGL Energy of Finland have completed the Torrens Island grid-scale battery energy storage system (BESS) in South Australia. The BESS plant, the second-largest operational battery in the country, will have the capacity to supply an hour’s worth of power to 75,000 homes in South Australia.
In addition to balancing the energy produced by the renewable energy source, the battery also gives the grid stability and reliability. Furthermore, the project is also said to uphold the country’s decarbonisation objectives. As per the company’s statement, this project will help Australia in achieving 100 per cent renewable grid and its net zero emissions target.
In July 2022, Wärtsilä, won a contract from Clearway Energy Group to provide a 500 MWac/2 GWh energy storage portfolio for Clearway’s solar-plus-storage projects. The five solar-plus-storage sites were a combination of energy storage and solar PV resources, and they are situated in Hawaii and California. The Daggett II and Daggett III projects, with a combined solar PV capacity of 482 MWac and 275 MWac/1.1 GWh of energy storage, were also a part of the portfolio.
