Silverton Wind Farm 220kV Transmission Line

See all Projects

Silverton Wind Farm in NSW comprises of 200MW (58 wind turbines) of energy into the network at Broken Hill. It was developed by AGL and constructed in 2018.

The power generated by this wind farm connects to the Transgrid 220kV network (Broken Hill) which is 25km from the wind farm substation.

CPP designed and constructed the 220kV substation and constructed the transmission line required to connect the wind farm to the TransGrid network.

KEY CHALLENGES
  • The project has presented a considerable challenge with hard rock being found in most foundation locations. This has required us to redesign and certify foundations at short notice and use a variety of means to excavate foundations.
  • The remote location of this project has presented challenges in terms of logistic support. This led to the development of plans that considered the long lead times to deliver items as well as the capacity limitations of local suppliers.
  • Powerline Design and Review
  • Clearing and Access Track Preparation
  • 25km of 220kV Transmission Line Construction on steel monopole structures
  • Testing and Commissioning
