Edify Energy and Sosteneo have announced the full operationality of the Koorangie Energy Storage System (KESS), located in the Gannawarra region of north-west Victoria.
Constructed by Consolidated Power Projects (CPP), the advanced battery system provides 185MW/370MWh of large-scale energy storage. A 15-year offtake agreement with Shell Energy is in place, and plays critical role in supporting the company’s decarbonisation and net zero future.

Through its System Support Agreement with AEMO, Koorangie ESS provides essential grid stability services and enables up to 300MW of new renewable generation in the Murray River Renewable Energy Zone (REZ).
Despite its rich wind and solar resources, north-west Victoria has faced grid constraints that limit renewable energy exports. Koorangie ESS addresses these challenges using Megapacks with Tesla grid-forming inverters, which maintain grid voltage and frequency—services traditionally provided by conventional generators. This technology plays a vital role in stabilising the network and unlocking the region’s full renewable energy potential.
Edify Energy executive chairman John Cole said, “This system seamlessly delivers critical system strength services to AEMO while dispatching clean, green electrons to the grid.
“It’s a powerful example of how advanced grid forming inverter and battery storage technologies can combine to solve some of the most complex challenges in Australia’s energy transition.

“Koorangie ESS is our third project in Kerang and our 12th major energy infrastructure development to reach commercial operation—an achievement that reflects the dedication, expertise, and resilience of the Edify team.”
Koorangie Energy Storage System is on the traditional land of the Barapa Barapa, Wamba Wamba and Yorta Yorta people, near the town of Kerang.
