The proposal is for a 330 kV transmission line from Harvey to Kwinana, a distance of approximately 102 km.
The first 51 km of the route parallels the existing Bunbury - Cannington 132 kV line from the Harvey Substation site almost to Pinjarra. There are a number of deviations to avoid major road intersections, dwellings and their environs and Pinjarra townsite. Following this , the route joins the existing Muja - Southern Terminal 330 kV line and follows it for most of the next 44 km. There is a deviation around existing domestic dwellings and small holdings at Anketell and the line then remains in a separate easement for the remaining 4 km to Mandogalup. The final 7 km of the line will be strung on the spare side of the double circuit structures presently carrying the Kwinana- Southern Terminal330 kV line.
