Waratah Super Battery passes second critical grid test
Waratah Super Battery on NSW Central Coast discharged 700 megawatts over two hours in a second test of its grid security role.
The Waratah Super Battery, Australia's most powerful, completed its second test of the Security Integrity Protection Scheme on Friday. The scheme allows the battery to act as a shock absorber during grid stress.
The battery discharged 700 megawatts over two hours, proving it can stabilize transmission lines and boost power import capacity. The battery then charged at 850 megawatts, drawing record amounts from the grid.
Built by Akaysha Energy on the Central Coast site of the closed Munmorah coal power station, the 1,650-megawatt-hour battery has been operating on an interim basis since late last year. A transformer failure delayed its full contract by more than a year.

Why it mattersThe battery is key to moving more renewable energy from the regions to cities and stabilizing the grid as coal generators close.
AustraliaThe Waratah battery is part of Australia's plan to keep the electricity grid stable as it shifts toward renewable energy and moves away from coal.
