Wärtsilä issued a press statement saying: “On a twelve-month rolling basis, the ES&O net sales by the end of Q3 2023 amounted to €983m ($1.04bn). On the same twelve-month rolling basis, the business turned to profitability.”

In August 2023, Wärtsilä and AGL Energy completed construction at the Torrens Island grid-scale battery energy storage system in South Australia.

The 250MW/250 megawatt-hour ESS installed at Torrens Island is expected to generate sufficient power to meet the needs of nearly 75,000 South Australian homes for an hour.
