The Challenger gold mine is located 740 km northwest of Adelaide in South Australia. It was operated by Kingsgate Consolidated Ltd until February 2016 when WPG Resources bought the mine.
At the time of the mine’s establishment, a reliable power supply was needed. The mine owners turned to Powerwest to deliver a build own operation (BOO) solution.
In 2002, Powerwest installed a 2.5MW power station at the site. Additional Cummins generators were installed in 2005, with a capacity of 5.6MW and, in 2010, a second power station was added with a capacity of 4MW.
In 2016, when WPG bought Challenger, all contractors were invited to retender. Powerwest was one of the few to win their tender. In 2016–17, both existing power stations were upgraded with new Cummins engines to further improve fuel efficiency.
