Construction of Australia’s Largest Transmission Project Is Powering Ahead
The 16ha Buronga substation is set to become one of the largest and most advanced in the Southern Hemisphere.

Australia stands at the cusp of an energy revolution, with ambitious plans to shift from fossil fuels to renewable sources. However, a critical challenge looms: connecting these new clean energy sources to the existing power grid. This challenge is at the heart of the country’s energy transition strategy.
The Australian Energy Market Operator (AEMO) has outlined a bold vision in its 2022 Integrated System Plan. This roadmap calls for a nine-fold increase in grid-scale wind and solar capacity, coupled with a tripling of firming capacity from sources like batteries and pumped hydro by 2050. To achieve this, Australia needs to construct 10,000km of new transmission lines—a daunting task that comes with a hefty price tag of AUD 12.7 billion.
These new transmission projects are vital for several reasons:
1. They enable the connection of renewable energy zones to the main grid.
2. They strengthen interconnections between states, improving energy sharing and grid stability.
3. They replace ageing infrastructure, enhancing overall system reliability.
Key projects in the pipeline include HumeLink in New South Wales, VNI West connecting Victoria and New South Wales, and Marinus Link between Tasmania and Victoria. Each of these plays a crucial role in the broader energy transition strategy.
However, the path forward is not without obstacles. Community opposition to new transmission lines, often driven by concerns about visual impact and property values, has led to project delays and cost overruns. The industry is grappling with how to balance the urgent need for new infrastructure with legitimate community concerns.
Innovative approaches are being explored to address these challenges. These include:
– Underground cabling for portions of transmission routes
– Improved community engagement and benefit-sharing programmes
– Advanced technologies to reduce the visual impact of overhead lines
