The Waratah Super Battery is now operating at 700MW—82% of its total capacity—following the successful repair and return to service of one of its transformers.
The $1 billion Waratah Super Battery is being built by Akaysha Energy approximately 25km south of the retiring Eraring coal-fired power station.

In November last year, Akaysha Energy notified the energy market of a temporary loss of capacity at the battery due to a transformer outage.
“Reaching 700MW represents a significant step in bringing one of Australia’s most important energy infrastructure projects online and enabling increased participation in the electricity market,” the company said in a statement.
“The Waratah Super Battery will continue to provide 350MW of the System Integrity Protection Scheme (SIPS) Service, with the other 350MW of capacity to be deployed into the National Electricity Market.
“The full 700MW SIPS service will be provided when High Voltage Transformer 3 (HVT3) is operating later this year and Waratah’s full 850MW/1,680MWh capacity is online.”
