REZ Transmission Line Rerouted to Protect Caves, Secures Support from 50 Additional Landowners
Breaking: Major Revision to Renewable Energy Zone Transmission Route
A critical revision to the planned transmission line for a key Renewable Energy Zone (REZ) has shortened the route by 2 kilometers, skirting sensitive cave systems and residential areas while gaining backing from 50 new landholders.

“These changes ensure minimal environmental and social impact without compromising the project’s essential role in Australia’s clean energy transition,” said Dr. Emily Tran, energy infrastructure analyst at the University of New South Wales. “The realignment reflects a balanced approach to community and ecological concerns.”
The updated corridor now avoids underground cave networks that could be disturbed by construction. Officials confirmed that 50 previously opposed landowners have shifted to supportive positions after the reroute was announced.
Route Adjustment Details
The original 200-kilometer path was trimmed by 2 kilometers in three separate segments. Project planners say the changes were driven by geological surveys and direct feedback from affected residents.
“We listened to community concerns about property proximity and cave preservation,” stated James Mitchell, project director for Transgrid. “The new alignment is a win-win for all stakeholders.”
The adjusted segment now runs along existing road corridors and farm boundaries, reducing the number of properties directly intersected by the line.
Background: Essential REZ Infrastructure
This transmission line is a backbone of the Central-West Orana Renewable Energy Zone in New South Wales. It will carry electricity from planned wind and solar farms to the national grid.

The project is deemed “essential” by the Australian Energy Market Operator (AEMO) to meet 2030 renewable energy targets. Without it, almost 3 GW of new renewable generation could be stranded.
Previous route drafts had faced strong opposition from landholders and environmental groups concerned about agricultural disruption and damage to fragile ecosystems, including limestone caves.
What This Means
The revision significantly de-risks the project. With 50 additional landholders now on board, compulsory acquisition notices for those properties will likely be avoided.
“This reduces legal challenges and accelerates the construction timeline,” noted Professor Kevin Ruddock, energy law expert at Sydney University. “It also sets a precedent for future REZ projects to engage proactively with communities.”
The remaining landholder negotiations continue, but the overall approval process is expected to move forward smoothly. Construction is slated to begin in the first quarter of 2026.
