Waratah Super Battery
To ensure NSW continues to have reliable energy supply following the anticipated closure of the Eraring Power Station, the NSW Government is delivering the Waratah Super Battery project. The project includes the largest standby network battery in the southern hemisphere, providing a service of up to 850 megawatts of capacity dedicated to supporting the transmission grid.
The Waratah Super Battery will operate as part of a System Integrity Protection Scheme (SIPS) designed to monitor transmission lines and enable the battery to act as a 'shock absorber' in the event of any sudden power surges, including from bush fires or lightning strikes.
By supplying additional on demand capacity, the Waratah Super Battery provides a virtual transmission solution that will increase the transmission capacity of the existing network, allowing electricity consumers in the Sydney, Newcastle, Wollongong demand centres to access more energy from existing generators.
