Northern Terminal to Neerabup Terminal 330kV Transmission Line

Project
Proposal description: 

The Northern Terminal (NT) to Neerabup Terminal (NBT) 330kV Transmission Line proposal (the Proposal) is located approximately 13 km north of Perth in the City of Swan and City of Wanneroo. The Proposal is for the construction of a new 330kV dual circuit transmission line between NT in Malaga and NBT in Pinjar, a length of approximately 29 km. The purpose of the proposal is to reinforce the North Region transmission network to remove constraints on existing connected generation and provide additional capacity to connect largescale renewable energy generation and meet future demand. The Proposal involves the following components: 

  • Construction of steel lattice towers, steel poles or hybrid of both options. For the purposes of this referral, it is assumed steel lattice towers will be used. 

  • Installation of 330kV overhead conductors, grounding wires and communications wires. 

  • Construction of a 4-m wide permanent maintenance access track centred on the line route. 

  • Establishment of a 60 m-wide vegetation clearance zone (ie, 30 m either side of the line route). Maximum vegetation height in this zone will be limited to 3 m.

In addition, the Proposal includes the following temporary construction activities: 

  • Construction access track. 

  • Break and winch sites every 6 km of line for stringing conductors. 

  • Clearing within a 20m wide corridor where necessary for turnaround areas, laydown/storage areas, laying of conductors and other construction activities.
