New South Wales, Victoria, and South Australia are now directly connected by EnergyConnect, Australia’s largest transmission project, enabling renewable energy to flow between the three states.
EnergyConnect’s western section has been energised, with new transmission lines linking the Buronga substation in southwestern NSW to Red Cliffs in Victoria and the South Australian border.
The Australian Energy Market Operator (AEMO) has commenced testing to ensure 150 megawatts (MW) of power can be safely supplied between the states.
According to Transgrid, the project developer, for the first time, renewable energy can now be shared directly between the three states, marking a critical milestone in building a more reliable, secure, and sustainable energy network.
Transgrid CEO Brett Redman described EnergyConnect as a “gamechanger” for Australia’s energy future.
“Inter-network testing has commenced on these new lines, bringing us closer to transferring renewable energy directly between NSW, South Australia, and Victoria for the first time,” Redman said.
“EnergyConnect is our first major transmission project in 30 years and the flagship for Australia’s energy transition. It will enhance system security and deliver cleaner, cheaper electricity for consumers well into the future.”
Delivered by Transgrid in partnership with Elecnor, EnergyConnect includes a 700KM NSW section stretching from Wagga Wagga to the South Australian border, with an extension to Red Cliffs in Victoria.
Redman acknowledged the extensive efforts behind the project, praising the contributions of landowners and local communities.
“The energisation of these new lines has taken millions of hours, and I’d like to thank everyone who has played a role in delivering Australia’s largest transmission project,” he said.,
“I would also like to specially recognise the landowners and local communities along the western alignment who have worked closely with us to deliver this nation-critical project. We are pleased to have delivered social and economic benefits to them – including jobs, support for local businesses, education and training opportunities and community grants.”
Construction is ongoing for EnergyConnect’s 540KM eastern section between Buronga and Wagga Wagga, involving over 1000 workers.
This phase includes the development of two transmission lines and a major substation, further reinforcing the National Electricity Market.
