Project EnergyConnect to start power grid transformation

Construction has now started on a $2.3 billion project, EnergyConnect, an electricity transmission line linking South Australia with NSW. More than 9000 km of cabling, enough to span from Sydney to Perth three times, will be used to deliver Australia’s largest electricity grid project.

CEO Brett Redman commented on the start of construction on Transgrid’s $1.8 billion infrastructure investment in New South Wales’s far west.

“EnergyConnect is a once-in-a-generation transmission project that will help to revolutionise the National Electricity Market and we are really pleased to be getting underway with this critical infrastructure,” he said. “The project will be a key component of the future grid, which will enable the integration of renewable generation and support the decarbonisation of the nation’s economy.

“By increasing wholesale electricity competition, EnergyConnect will help drive down electricity bills and once completed, the project is expected to save NSW energy customers $180 million a year.”

EnergyConnect is a 900 km interconnector that will enable the sharing of energy between New South Wales, South Australia and Victoria for the first time. Transgrid is building the 700 km NSW section from the South Australian border to Wagga Wagga and South Australia’s ElectraNet has started building the remaining 200 km from the border to Robertstown, SA.

Early works have already commenced in western NSW to provide construction access points ahead of major works scheduled for July. Over the course of the project, Transgrid’s construction partner SecureEnergy will erect 1500 new transmission towers, using more than 30,000 tonnes of steel.

“We are excited to progress the project which is of enormous significance to the nation’s energy consumers,” said EnergyConnect Project Director Stephen Troughton. “SecureEnergy will soon start building the first stage in NSW, which includes construction of 135 km of new transmission line between Buronga and the SA border, a 33 ha expansion of the existing Buronga substation and further 22 km of transmission line to the Victorian border near Red Cliffs.”

SecureEnergy Project Director David Whatmough said, “The scale of the project means we will engage a workforce which is on an unprecedented scale for a transmission asset construction project in this country. EnergyConnect is one of the first of many that will change the industry across Australia and represents a significant part of the transition taking place in the energy sector. From a power engineering construction perspective, it provides a fabulous opportunity to grow the next generation of people who want to work in this industry.”

ElectraNet Interim Chief Executive Rainer Korte said, “EnergyConnect is a landmark project of national significance that will enable more renewable energy and improve the affordability, reliability and security of electricity supply. We are delighted to see the start of construction on this critical project in both South Australia and NSW.”
