First Super-Grid Tower Signals Major Progress in National Energy Plan
A critical and tangible step in Australia’s transition to a renewable-powered grid has been taken in regional New South Wales, with the installation of the first transmission tower for the nation’s inaugural Renewable Energy Zone (REZ). The 70-metre-high, 500-kilovolt (kV) tower marks a significant physical milestone for the Central-West Orana REZ, a landmark project designed to connect vast new renewable energy sources to the national electricity grid.
The tower, pre-assembled in 19 sections from 2,862 steel components and 6,252 bolts, was lifted into place by network operator ACEREZ, according to project lead EnergyCo. It is the first of many that will form a 240km network of new high-capacity transmission lines, acting as a renewable energy superhighway.
This development provides a concrete answer to the question many are asking: is the ambitious plan to rebuild Australia’s grid for the renewable era actually making progress? This first tower suggests the answer is yes. The Central-West Orana REZ is a cornerstone of the NSW Government’s energy roadmap and a key part of the broader national strategy to ensure grid stability as traditional coal-fired power stations retire.
Unlocking Billions in Renewable Investment
The Central-West Orana REZ, spanning a 20,000km² area, is projected to be a powerhouse for the National Electricity Market (NEM). Once operational from 2028, it is expected to unlock an initial 4.5 gigawatts (GW) of network capacity—enough to power more than two million homes. This new infrastructure is forecast to attract up to $25 billion in private investment for new wind, solar, and energy storage projects.
“Reaching this milestone reflects years of planning and collaboration with landholders, communities, industry and our delivery partner ACEREZ,” said EnergyCo Chief Executive Officer, Hannah McCaughey. “EnergyCo is focused on making sure this infrastructure is delivered safely, efficiently and in a way that creates lasting benefits for the Central-West Orana region and the state.”
The economic benefits are already being realised locally. The project is expected to create 1,850 direct construction jobs and around 930 ongoing operational roles. More than 110 local businesses are already engaged in the project, with over a third of the current workforce from the surrounding region.
A Blueprint for Australia’s Energy Future
The Central-West Orana REZ is the first of five such zones planned for NSW, with others designated for the New England, Hunter-Central Coast, Illawarra, and South West regions. These zones are strategically located in areas with abundant sun and wind resources, streamlining the connection of new-generation projects to the grid.
In addition to the economic and energy benefits, the project includes significant community investment. A $128 million Community and Employment Benefit Program is in place, with over $72 million already awarded to 75 local projects, ranging from housing and water infrastructure to skills training and sports facilities.
The successful rollout of this critical transmission infrastructure is seen by market operators and governments as essential for maintaining reliable and affordable electricity. By grouping generation and transmission development, REZs are designed to deliver large amounts of clean energy, which AEMO and other bodies state will place downward pressure on wholesale electricity prices through increased competition and supply. While this single tower is just the beginning, it represents a visible and vital step forward in constructing the grid of the future.
