The Waratah Super Battery project, based at the former Munmorah coal-fired power station, serves as a System Integrity Protection Scheme (SIPS) to absorb sudden power surges from events like bushfires or lightning strikes. It enhances transmission capacity, enabling consumers in the Hunter, Sydney, and Illawarra regions to access more energy from current generators.

The project includes a battery system ensuring a continuous active power capacity of at least 700 MW and a usable energy storage capacity of 1400 MWh, supported by paired generators across NSW for technical services.

TransGrid operates a communication system to detect network issues and swiftly adjust generator output and battery discharge, while network enhancements upgrade transmission lines and substations to increase overall capacity.

Consolidated Power Projects (CPP) is responsible for designing and constructing critical components of the Waratah Super Battery, including a 330kV substation, an overhead line (OHL) connection to the Munmorah Substation, and an 850MW Battery Energy Storage System (BESS). The specifics include:

• Landing of 145 Static Step Up Transformers (SUTs) on-site
• Landing of 288 inverters on-site
• Landing of 2352 Batteries
• Landing of 288 Combiner segments
• Landing and installation of 12 RMU Buildings
• Landing and installation of 3 Switchgear buildings and 1 Control Building
• Installation of the gantry
• Installation of all 330kv primary Plant within the substation
• Over 3000 Truck movements to install the BESS equipment
