Akaysha Energy’s Waratah Super Battery is now operating at 700MW and 1,680MWh following the successful return to service of High Voltage Transformer 2 (HVT2), the BlackRock-backed developer confirmed in a market update today (4 June).
The 700MW figure represents 82% of the facility’s total 850MW power output and its full rated energy capacity of 1,680MWh.
Of the 700MW now available, 350MW will continue to be committed to the System Integrity Protection Scheme (SIPS) service contracted with transmission operator Transgrid, with the remaining 350MW to be deployed on a merchant basis into the National Electricity Market (NEM).
