Waratah Super Battery reaches full operational capacity in Australia

The Waratah Super Battery, Australia’s most powerful energy storage facility, has completed its commissioning and is now operating at full capacity. Owned and operated by Akaysha Energy, the facility features a power rating of 850 MW and a storage capacity of 1,680 MWh.

Designed to act as a “giant buffer” for the New South Wales electricity grid, the battery serves the System Integrity Protection Scheme (SIPS). It is engineered to respond rapidly to grid disturbances by discharging electricity when lines fail or overload, helping to stabilize the system as aging coal-fired power plants are decommissioned. Recent tests successfully demonstrated the battery's ability to supply an average of 700 MW for two hours.

The project faced significant delays, including the financial collapse of a primary battery supplier and technical issues involving damaged transformers. However, the Australian Energy Market Operator (AEMO) has now granted final authorization for full operation. New South Wales Energy and Climate Minister Penny Sharpe stated that the project is a decisive step toward a reliable, modern, and renewable-friendly energy system.
