Canadian firm Hydrostor has struck a deal to provide back-up power to the remote New South Wales outback town of Broken Hill using a compressed air energy storage plant that will be built in an underground cavern at one of the region’s closed mines.

Australia’s largest electricity transmission project has hit a snag with a major union alleging transmission line workers delivering the New South Wales stretch of the $2 billion-plus (USD 1.32 billion) Project EnergyConnect electricity interconnector have been working in unsafe and non-compliant conditions.

Australia’s largest electricity transmission project EnergyConnect has taken another step towards completion with the arrival of two 120 MVA capacity synchronous condensers that will sit at the heart of the Buronga substation in western New South Wales.

Landowners in the path of the multi-billion-dollar HumeLink transmission project claim Transgrid is relying on flawed economics that favour overhead lines with a new report suggesting the network operator’s costings for putting the cables underground are out by almost 60%.

Australia’s largest transmission network operator Transgrid has struck a deal with Chinese manufacturer ZTT International for the delivery of more than 17,500 kilometres of high-voltage conductors as it looks shore up supplies of key electrical equipment needed to deliver critical transmission projects.

Transgrid, Australia’s major grid operator, plans to soon launch a competitive process to procure grid support services from third-party battery operators as it looks beyond traditional network infrastructure to help maintain the reliability of electricity supply in two growth regions in New South Wales.

Construction of Australia’s largest electricity transmission project continues to roll on with network operator ElectraNet announcing it has achieved more than 70% completion of the South Australian component of the 900-kilometre EnergyConnect project that will link power grids across three states.

New South Wales transmission network operator Transgrid plans to spend $16.5 billion (USD 11.22 billion) to grow the state’s power system over the next decade to ensure the “secure operation” of the grid at up to 100% instantaneous renewables.

Construction of the South Australian section of the $2.3 billion (USD 1.56 billion) EnergyConnect infrastructure project, which will link power grids across three states, is now more than 50% complete with ElectraNet announcing the high-voltage interconnector is on track for release of full power transfer capability by mid-2026.

Today marks a historic moment in Australia’s energy transition with AGL Energy completing the shutdown of its coal-fired Liddell power station in New South Wales with the last operating turbine having been switched off for the final time.
