Finnish marine and energy technology group Wärtsilä will deliver what it claims is “Australia’s largest DC-coupled hybrid battery energy storage system (BESS)” for the National Electricity Market (NEM).
The project will be Wärtsilä’s ninth BESS site in Australia, expanding the company’s local footprint to 1.5GW/5.5GWh of capacity. The battery storage system is expected to be operational in 2028. The order will be booked by Wärtsilä in Q4 2025.
The announcement builds on Wärtsilä’s previous DC-coupled project in Australia, the 64MW/128MWh Fulham Solar Battery Hybrid project for Octopus Australia. Announced in April 2025, the project represented one of the first large-scale DC-coupled hybrid battery systems in the NEM.
Wärtsilä has not disclosed what project or developer it will supply the battery storage system for. However, the largest announced DC-coupled hybrid battery storage system in the NEM at the time of writing is Lightsource bp’s 49MW/562MWh Goulburn River solar-plus-storage site, which recently started construction.
