Community invited to shape NSW’s renewable future through Mount Piper–Wallerawang transmission line upgrade

October 8, 2025

As the NSW community prepares for a greener future, it’s all hands on deck as residents from Wallerawang, Lidsdale and Portland are invited to voice their opinions concerning the Environmental Impact Statement (EIS) for the Mount Piper to Wallerawang Transmission Line Upgrade Project. Covered in a recent report, this transformative project supports NSW’s critical transition towards renewable energy sources.


The Mount Piper to Wallerawang Transmission Line Upgrade Project will forge a new 8km 330 kV transmission line between the two transmission substations. This essential upgrade is a step towards a more sustainable future, underpinning the NSW Government’s Central-West Orana Renewable Energy Zone. A project of this scale will help secure a stable supply of more affordable and cleaner energy to the people of NSW through the high-voltage grid.
The project’s commitment to sustainable progress and community inclusion is evident in their meticulous planning. As Jennifer Hughes, the Executive General Manager of Delivery, highlighted, “Transgrid would like to thank the local community for their help in identifying the preferred route, which uses an existing transmission line corridor and ensures the lowest possible impact on local residents, businesses and the environment.” The communal focus displayed here highlights the potential of public participation in addressing environmental concerns, fostering a sense of unity.


To mitigate potential environmental, economic and social impacts, the project team has prepared a detailed EIS. It meticulously maps out environment-related concerns across 15 technical areas, including heritage, biodiversity, land use, air quality, noise, traffic and transport, and visual amenity. The EIS is available for public exhibition, and to encourage openness and transparency, Transgrid is inviting the community to attend information sessions this month.

The opportunity for public to contribute their views is open until 24th September, it offers locals an empowering opportunity to shape their energy future. This level of community involvement is crucial, amplifying the importance of everyone’s role in transitioning towards a greener future. To check out the EIS or to make a submission, interested parties are encouraged to visit the DPHI website. For additional resources, including an accessible EIS guide, fact sheets and submission details, please visit Transgrid’s website.

On the path to a more sustainable future, projects like the Mount Piper to Wallerawang Transmission Line Upgrade are essential – and so too is your voice. By creating an accessible platform for community input, we all take a step toward a greener, more sustainable, and community-focused energy solution. This is a ringing testament to the transformative power of energy infrastructure when it’s grounded in and driven by the community it serves.
