Project Summary

Blyth West substation is located near the Blyth township in South Australia and connected to the Snowtown Wind Farm (Stage 2) via a 275kV mono-pole overhead line.

The Blythe West substation was constructed as a three circuit breaker mesh bus arrangement allowing for a future upgrade to a full breaker and a half configuration over two diameters with relative ease.

The Blythe West substation construction involved:

  • The full design, procurement and construction of the 275kV network connection
  • The installation of 5kms of OPGW on the existing 275kV Pi Structured Para-Bungama overhead line which required structural upgrades to the affected Pi structures and the design and installation of a 275kV insulated lattice turn-in tower.
