EnergyConnect is proud to announce its most significant milestone yet with the successful connection of the NSW, Victoria and South Australia power grids and integration into the National Electricity Market (NEM).
The EnergyConnect team has completed the first stage of the project, EnergyConnect West, an expansion of the Buronga substation the largest and most complex facility of its kind in Australia and delivery of new transmission lines from the substation to the South Australia border (Line 1) and Red Cliffs in Victoria (Line 4).
The energisation of Line 1 stretching 135km on 31 October followed the commissioning on Line 4 (24km) in September, with all three states now connected via the expanded Buronga substation.
Removal of the old tower structures on Line 4 has also now been successfully completed with rehabilitation works ongoing.
Works on EnergyConnnect East between Buronga and Wagga Wagga are progressing well. All transmission tower foundations are complete and tower, assembly, erection and line stringing activities are well advanced on Line 2 from Buronga to Dinawan substation, near Coleambally, and Line 5 from Dinawan to Wagga Wagga.
Works are also continuing across EnergyConnect's network of substations:
Wagga Wagga substation - An extensive program of civil, mechanical and electrical works to expand the substation and prepared for connection to the new transmission line was completed in June 2025.
Buronga substation – the second stage of the substation's expansion to prepare the site for connection to EnergyConnect East, and ultimately deliver the full 800mW transfer capacity of the interconnector is nearing completion.
Dinawan Substation – Civil and electromechanical works are well-advanced at the site. The machinery hall to house two synchronous condensors is complete and these units have been delivered to site for installation and testing.
