Update regarding the Waratah Super Battery
Akaysha Energy recently notified the energy market of a temporary loss of capacity at the battery due to a transformer outage. The Waratah Super Battery is still operating at 350MW capacity and actively bolstering energy security for NSW’s grid.
The battery continues to meet its System Integrity Protection Scheme (SIPS) service requirements of 350 MW, which is the interim commercial operating capacity.
During ongoing Hold Point testing to transition the battery to full capacity, issues were identified with two transformers. There is no impact to the NSW electricity grid as the WSB remains operational and continues to meet its SIPS service requirements of 350MW.
The battery’s remaining capacity is expected to come online during 2026.
