- Ausgrid takes a significant step toward achieving its environmental goals, supported by Schneider Electric.
- The collaboration saw the introduction of alternate environmentally friendly SF6-free Distribution Switchgear into the Ausgrid Distribution Network.
- Ausgrid’s new SF6-free kiosk pad substation showcases Australia’s capability to create a greener network.
Ausgrid, the largest distributor of electricity on Australia’s east coast, has partnered with Schneider Electric, a leader in the digital transformation of energy management and automation, to decarbonise its grid operations.
As part of Ausgrid’s comprehensive sustainability strategy, this collaboration marks a significant step on the path toward achieving its environmental goals by introducing SF6-free Distribution Switchgear into the Ausgrid Distribution Network.
“Since the 1980s, Ring Main Units (RMUs) have used SF6 as the insulation medium due to its superior dielectric properties. Unfortunately, SF6 gas is 23,500 times more potent than CO2, posing a substantial environmental risk if leaked. Until now, no viable alternative existed. Our Pure Air SF6-free switchgear changes that, demonstrating our ongoing commitment to providing sustainable solutions for our partners,” said James Hunt, Vice President for Power Systems at Schneider Electric.
Engaged by Ausgrid, Schneider Electric developed an SF6-free kiosk pad substation, designed with internal arc containment to ensure any HV arcs or faults are contained within the kiosk. This crucial safety feature is designed to protect both operators and the public, requiring no modifications to Ausgrid’s existing enclosure.
“This is one of the first internally arc-rated SF6-free kiosk designs on the market, showcasing our capability to create a greener network across Australia. This solution will effectively prevent 35,000 kg of CO2-eq from entering Ausgrid’s network, while maintaining the same high levels of safety and operation,” added James.
Ausgrid’s Head of Design & Engineering Services Brett Hawkeswood said: “I am really delighted that we have had this opportunity to team with Schneider on our journey towards decarbonisation. Not only are we reducing our reliance on SF6 gas, we are also strengthening important safety features on the network.”
The new kiosk also features automation capabilities with Schneider’s T300 technology, allowing the control room to perform switching commands remotely. Additionally, it integrates seamlessly with Ausgrid’s Advanced Distribution Management System (ADMS) provided by Schneider Electric, ensuring optimal grid reliability.
