The proposed route for the Western Victoria Transmission Network Project (WVTNP) has been announced, following 18 months of extensive investigations, field surveys and consultation.
WVTNP Executive Project Director, Stephanie McGregor, said the route for the 190km transmission line between Sydenham and Bulgana had been designed to run along existing transmission line easements and at a maximum distance from houses as much as possible, and to minimise impacts – including on Aboriginal cultural heritage, agriculture, and vegetation.
“Determining this proposed route is a positive step toward unlocking more clean, renewable energy as the state moves to sustainable green power in coming years,” Ms McGregor said.
There are three locations along the route where alternative options are still being investigated – at Hepburn Lagoon, Darley and Melton Aerodrome – due to potential visual, landscape, Aboriginal cultural heritage and aviation impacts.
Ms McGregor said AusNet Services had planned to finalise the route by the end of this year, but it was a complex project and it was important to take the time to investigate these alternatives.
“Sharing the proposed route now will ensure much-needed clarity for around 220 of the 465 landholders that were within the single corridor. They now have the confirmation that their property is not on the proposed route,” Ms McGregor said.
AusNet Services has also released the preliminary findings of its investigation into undergrounding the transmission line, including full and partial undergrounding.
The investigation has found that undergrounding the transmission line would:
- Require significant soil and vegetation removal and disturbance of Aboriginal cultural heritage
- Limit opportunities for future renewable development
- Not meet the technical availability and reliability requirements of the electricity system
- Cost approximately 16 times more
As a result, overhead construction has been recommended by the investigation.
AusNet is still investigating undergrounding in some sections as part of the visual amenity and landscape assessments currently underway as part of the Environment Effects Statement (EES).
The key findings of the investigation have been shared with the community and published on the WVTNP website, while the full report will form part of the EES for the project.
AusNet Services’ Land Liaison Officers are now contacting each landholder within the proposed route to discuss their specific land use and requirements, the proposed route, easements and compensation.
