Koorangie Energy Storage System (KESS)

The Koorangie Energy Storage System (KESS) is a 185MW / 370MWh lithium-ion Battery Energy Storage System (BESS) located near Kerang, in Northern Victoria (Australia). KESS serves as a cornerstone of the Murray River Renewable Energy Zone.

Originally developed by Edify Energy, a leading Australian renewable energy developer, the project was acquired by Sosteneo on behalf of clients in October 2023. It commenced commercial operations in June 2025.

KESS has been awarded a 20-year System Support Agreement with the Australian Energy Market Operator (AEMO) to deliver system strength services that enhance grid stability and increase renewable hosting capacity in the Murray River region. The project is also supported by a long-term offtake agreement with Shell Energy.

KESS is on the traditional land of the Barapa Barapa, Wamba Wamba and Yorta Yorta people. Sosteneo acknowledge the traditional custodians of this land, whose rich culture is deeply connected to the rivers, lagoons, creeks, and wetlands of their nation.

KESS achieved each of its sustainability commitments including support of the Victorian Aboriginal Enterprises. These businesses provided a range of goods and services including site huts, construction materials, general labour and traffic management.

KESS has also completed social safeguard screening in accordance with the EU Taxonomy. All major project suppliers and counterparties were analysed to ensure that the project meets robust social and ethical standards.
