Waratah battery proves grid-rescue role with 700-850 MW tests in NSW

Australia’s Waratah battery in New South Wales demonstrated its grid-safety role by delivering about 700 MW for two hours and then pulling roughly 850 MW, marking its second full‑power test in three days after a transformer failure sidelined it for almost a year. The tests rely on a System Integrity Protection Scheme to relieve stressed transmission lines by coordinating with nearby generators, showing batteries as real-time grid valves rather than mere price arbitrage assets. A replacement transformer was energized in September after the 2025 failure, and the project aims to bolster the grid as coal plants retire and more wind/solar reach cities.
