Transgrid specialists deliver Australian-first control system to support Waratah super battery project

The $16 million (USD 10 million) System Integrity Protection Scheme (SIPS) Control System with paired generation has become operational following the first stage of commissioning of the New South Wales (NSW) government’s Waratah Super Battery Project.

Transgrid Executive General Manager of Delivery Jennifer Hughes said: “The SIPS Control System is the largest automated scheme of its kind in Australia, monitoring 36 transmission lines across NSW in real time, detecting overloading and responding in seconds. 

“In network contingency events such as lightning strikes, the SIPS acts as a shock absorber to return the network to a stable condition and maintain continuity of supply for consumers.”

“It’s like an insurance policy for NSW and the whole system is triggered automatically, making it fast and reliable in responding to a system event.”

The scheme, which was designed and installed by Transgrid specialist teams at 19 sites across NSW, helps transfer more power through existing transmission lines by temporarily increasing their capacity.

It can automatically detect potential line overloads and signals the Waratah Super Battery to discharge stored energy into the network. Simultaneously, the SIPS will signal hydro, wind and solar-paired generators in the New England and Snowy regions to reduce output to balance supply across the grid.

“The SIPS Control System represents a true feat in detailed design and innovation to provide real benefits to consumers,” Ms Hughes said.

“Transgrid is pleased to be working with EnergyCo and Akaysha Energy to deliver the Waratah Super Battery Project.”

The battery storage system that gives the Waratah Super Battery Project its name is situated at the former Munmorah Power Station site. The first 350 MW (700 MWh) of the project’s battery capacity have come online in the lead-up to full operation later this year.

At 850 MW/1,680 MWh, it is one of the world’s most powerful grid-scale batteries, allowing electricity consumers in the Hunter, Sydney and Illawarra to access more energy from existing transmission infrastructure in the state.

As Network Operator, Transgrid has connected the Waratah Super Battery to the grid via its existing Munmorah substation.

To support the project, Transgrid has also carried out upgrades to 22 substations and four existing transmission lines across NSW to deliver additional energy to consumers when required.
