Construction on the EnergyConnect transmission line continues, with works ramping up on the project’s eastern alignment.
Transgrid and its construction partner Elecnor Australia are building the 700km New South Wales section of EnergyConnect from Wagga Wagga to the South Australian border and into Victoria.
Transgrid Executive General Manager of Major Projects, Gordon Taylor, said, “The Riverina is at the heart of the clean energy transition and is in the box seat for growth as construction of this nation-critical project advances.
“EnergyConnect is providing a wide range of social and economic benefits to the Riverina including jobs, skills development, education and training, local business support, and funding for not-for-profit organisations to boost community facilities and services.”
More than 1,000 workers are progressing construction of the 540km eastern leg of the project between Wagga Wagga and Buronga, including:
- Opening of a new 460-worker accommodation camp at Bundure, near Coleambally, with construction of another 250-bed camp underway on the Cobb Highway near Hay. These facilities will complement existing worker accommodation camps at Lockhart (240 beds), Balranald (268 beds) and Buronga (411 beds).
- Construction of a world-class substation at Bundure, with 225,000t of dirt and gravel imported to site. Crews have constructed the substation bench by shifting 1,700t of materials per day. The Dinawan substation will be home to sophisticated electrical equipment including shunt reactors, synchronous condensers, step down transformers, and capacitor banks. The 330kV substation will enable better power flows between New South Wales, Victoria and South Australia, and support the development of new electricity generation in nominated renewable energy zones in the region.
- Crews have drilled and poured concrete foundations for 412 tower sites, assembled 118 towers, and erected 45 towers on the two lines between Wagga Wagga and Buronga.
- Works are well underway to expand the existing Wagga Wagga substation with the extension of the existing bench, pouring of concrete foundations, and installation of cable trenches and the Earth grid.
Mr Taylor said that EnergyConnect has so far invested more than $158 million with 197 local and First Nations businesses along the 700km project alignment.
“In the Riverina more than 80 local businesses have been engaged as subcontractors or suppliers to the project, generating an investment worth $55 million. Procuring goods and services locally helps local businesses grow, develop skills, and create jobs.”
Local Riverina businesses supplying the project include:
- Kurrajong Timber (Wagga Wagga)
- Absolute Mesh and Steel (Wagga Wagga)
- Kennards Hire (Wagga Wagga)
- Sturt Motel (Balranald)
- BDS Automotive (Balranald)
- BIG4 Holiday Park (Deniliquin)
- Caruso Bros. Transport (Deniliquin)
“We are proud to be working with Riverina communities and businesses to deliver this nation-critical project which will provide cleaner and cheaper renewable energy to families and businesses, and help Australia meet its emissions reduction targets,” Mr Taylor said.
Elecnor Australia Project Director, Felipe Delgado, said that he was proud of the construction milestones being achieved on multiple work fronts along the alignment.
“We have now completed 55 per cent of the total project tower foundations and more than half of those have been completed on the eastern alignment since the beginning of this year,” Mr Delgado said.
“We are also moving ahead with tower assembly, erection and the preparation of stringing on this line.”
Meanwhile, works are nearing completion on EnergyConnect’s western alignment with construction of the 135km line between Buronga and the South Australian border completed. Commission testing is underway on one of the largest and most complex substations in the Southern Hemisphere at Buronga, while stringing works on the line from Buronga to Red Cliffs in Victoria is progressing.
