Transmission Line from Pinjar Gas Turbine to Cataby Substation

Proposal description: 

The proposal is to build a transmission line with a maximum capacity of 330 kV from the Pinjar gas turbine station to the Cataby substation. The transmission line, which is primarily lattice tower construction up to 60 m high, traverses State Forest 65 South (Gnangara Park), Bush Forever Site 380, Gingin Stock Route Nature Reserve, State Forest 65 North and private property.

The proposed line route is approximately 123 km long and involves the permanent clearing of up to approximately 2.9 ha of vegetation for the tower sites and tower access roads and the temporary clearing of up to approximately 38.4 ha for construction activities including line stringing. Of this, approximately 1.9 ha of permanent clearing and 23 ha of temporary clearing are within land managed by the Department of Conservation and Land Management (CALM).

The transmission line will be constructed in a 60 m management corridor where vegetation directly under the transmission line will be maintained at 9 m in height. The vegetation along the majority of the proposed route is less than 9 m in height and should not require management.
