Transmission Line 99M forms an approximate 73 km 132 kV single circuit connection between the Yass 330 kV substation and the Murrumburrah 132 kV substation, located in the Southern Tablelands region. To facilitate the grid connection of the Coppabella Wind Farm development, TransGrid is proposing to rebuild an approximate 39 km section of Line 99M between the Coppabella Wind Farm (at Structure 143) and Yass substation as a double circuit line (the project). The rebuilt section of Line 99M would comprise new 40 metre high steel or concrete pole transmission structures, which would be up to 20 meters higher than the existing wooden pole structures. The project would also involve the construction of a new switch bay and associated electrical and communications connection works at Yass substation.
