Project elements

Elements of the project include:

  • Installation of nine steel poles;
  • The replacement of old timber poles with new timber poles; and
  • Stringing of new power and earthing wires on poles.

Project background

Transmission lines transport high voltage electricity from generation stations to substations, where power is reduced to lower voltages for distribution to homes and businesses.

In preparation for the transmission line upgrade, Western Power has carried out work on the distribution line that traverses along a section of the transmission line route.

Construction and installation of the transmission line has been completed and was energized in December 2007.

Works to finalise the project are expected to be completed mid 2009.
