Australian energy infrastructure company Gateway Energy Pty Ltd has hit a significant construction milestone, successfully completing full-scale load testing to 110% of ultimate load on its 45-metre Atlas330 suspension structure — developed specifically for Powerlink Queensland’s CopperString 2032 project.
What Was Tested? The Atlas330 is a suspension structure designed for 220–330kV transmission applications. The full-scale load test, completed to 110% of ultimate load, confirms the structure’s structural integrity and readiness for real-world deployment across Queensland’s transmission network.
Why Does This Matter? While the structure was purpose-developed for CopperString 2032, Gateway Energy says the real breakthrough isn’t the geometry — it’s what it unlocks:
- 🚀 Faster construction timelines
- 💲 Lower project costs
- 🔄 Versatility across a broad range of 220–330kV projects
With Australia’s lattice tower builders in high demand on 500kV projects, having an efficient, proven solution for the 220–330kV space could be a genuine game-changer for Queensland’s transmission build-out pipeline.
The Bigger Picture CopperString 2032 is a ~1,000km, $5 billion transmission project connecting the North West Minerals Province to the National Electricity Market. Projects of this scale depend on innovative, cost-effective construction solutions — and successful milestones like this one give confidence that the delivery chain is maturing.
As Gateway Energy put it: “There’s no transition without transmission.”
