NSW's Waratah Super Battery hit final commercial ops - 850 MW on an old coal site, built to catch grid shocks in milliseconds
Akaysha Energy reached final commercial operations at the Waratah Super Battery in New South Wales on 28 September 2026: 850 MW / 1,680 MWh on the former Munmorah coal-fired power station site. NSW Government commissioned it; Akaysha builds, owns and operates; Transgrid's System Integrity Protection Scheme (SIPS) is the fast grid-protection layer it plugs into.
