CopperString 2032: Officials and Experts Weigh In on What the Power Line Means for TownsvilleUpdated

The CopperString 2032 project, a proposed 1,500-kilometre high-voltage transmission line that would connect the North West Minerals Province to the national electricity grid via Townsville, has moved from engineering blueprint to urgent political conversation, with officials and energy specialists now publicly staking out positions on whether it can deliver what its backers promise.

The timing matters. Queensland's state government has committed $500 million toward the project's development costs, and a final investment decision is expected before the end of 2026. For Townsville, which already anchors the Copperstring corridor as its eastern terminus near the Powerlink substation at Stuart, the window to shape how the city benefits is narrowing fast.

Townsville Enterprise Limited, the region's peak economic development body based on Sturt Street, has been among the loudest institutional voices pushing for the project to lock in local procurement requirements. The organisation has pointed repeatedly to the Lansdown Eco-Industrial Precinct, the 7,300-hectare industrial park roughly 40 kilometres southwest of the CBD, as the site most likely to absorb the manufacturing and processing activity that a grid connection would enable. Without CopperString, Lansdown's hydrogen and green metals ambitions remain largely theoretical.

What the Experts Are Saying

Energy analysts have been less uniformly enthusiastic. Researchers at the Queensland University of Technology's Centre for Clean Energy Technologies and Practices have noted that the project's financial viability depends heavily on whether critical minerals production in the Cloncurry and Mount Isa region ramps up on the timeline the state government has projected. The minerals province holds an estimated $45 billion in untapped copper, cobalt and zinc, but global commodity prices and sovereign risk factors could slow mine development regardless of what happens with the grid.

The Townsville Chamber of Commerce has framed CopperString as inseparable from the city's hydrogen hub ambitions, which received a $2 million feasibility boost under the federal government's Regional Hydrogen Hubs program in 2023. Chamber figures have argued publicly that without transmission infrastructure, the Port of Townsville, currently undergoing a $233 million channel upgrade, cannot realistically position itself as an export gateway for green ammonia or hydrogen derivatives. That argument has gained traction with federal infrastructure officials who see the port expansion and CopperString as a package.

Defence industry representatives have raised a separate but related concern. With the 3rd Brigade at Lavarack Barracks and RAAF Base Townsville together employing more than 6,000 personnel and contractors across the northern suburbs, energy security analysts have flagged grid resilience as a national security issue, not merely a commercial one. A more robust northern Queensland grid, the argument goes, reduces the vulnerability of critical defence infrastructure to supply disruptions, a point that has found sympathetic ears in Canberra given the current focus on northern Australia defence posture.

What Happens Next

The immediate pressure point is a Queensland government review of the project's Environmental Impact Statement, which closed its public comment period in June. Powerlink Queensland, the state-owned corporation managing the EIS process, is expected to deliver its assessment to the Department of Energy and Climate by October 2026. If that assessment is favourable, the final investment decision could come before Christmas, setting up a construction mobilisation phase that Townsville's construction sector, still rebuilding capacity after the 2019 flood recovery works wound down, would need to absorb quickly.

For residents in the industrial western corridor between Bohle and Stuart, the more immediate question is what construction-phase activity looks like on the ground, how many workers, where they'll be housed, and whether local subcontractors on projects like the existing Townsville Ring Road upgrades can transition into CopperString supply chains. Townsville City Council has been asked to provide a workforce readiness submission to the state government by September 30. Whether local businesses are organised enough to make that case clearly will go a long way toward determining how much of a $5 billion project actually stays in the region.
