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.
Transgrid engaged fellow Quanta Services Company – Consolidated Power Projects (CPP) as the principal contractor. CPP designed and constructed the 220kV Sub Station and Quanta Lines constructed the transmission line required to connect the wind farm to Transgrid network.
The project has presented considerable challenge with hard rock being found in most foundation locations. This has required QL 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 has led NJC to develop plans that consider the long lead times to deliver items as well as the capacity limitations of local suppliers.
