Located about 100km north of Sydney and approximately 25km south of the retiring Eraring coal-fired power station, the Waratah Super Battery resides in a 138,000 square metre site (over 8 Australian Football fields).
The Waratah Super Battery is capable of providing a guaranteed continuous active power capacity of at least 700 MWs and a guaranteed useable energy storage capacity of at least 1400 MWh.
By operating as part of a System Integrity Protection Scheme (SIPS) to increase the transmission capacity of the existing network, the BESS will allow more power to flow from existing generators to meet the needs of the families and businesses of NSW.
The size of the Waratah Super Battery also allows Akaysha to trade the additional capacity in the electricity market placing further downward pressure on the cost to electricity users in NSW.
Akaysha Energy was appointed by Energy Corporation of NSW to develop the battery.
It's on track to be fully operating by mid-2025.
Project partners include: Powin for battery hardware and software, Consolidated Power Projects (CPP) for engineering, procurement and construction, EKS (now part of Hitachi Energy) for power conversion systems and Wilson Transformer Company for power transformers.
