New Energy Insights – Bulletin – EOI for Waratah Super Battery

The New South Wales Government is advancing its plan to build the “biggest network battery in the southern hemisphere” by 2025 as it looks to shore up a reliable energy supply ahead of the impending closure of the coal-fired Eraring Power Station.

The 1.4GWh Waratah Super Battery will, together with other minor transmission upgrades, allow Sydney, Newcastle and Wollongong consumers to access more energy from existing electricity generation.

The Energy Corporation of NSW (EnergyCo) has launched a competitive procurement process to identify suitable battery developers and appropriate site(s) for the development of the Waratah Super Battery. See indicative timeline below:
