On video: Natural gas power at zinc and copper mine, Kalgoorlie, Australia

Four Cummins QSV91 generator sets are enabling IGO to reduce costs at its remote zinc and copper Jaguar Mine in Kalgoorlie.

After choosing gas-powered systems to take advantage of cost-saving natural gas,
Jabiru selected Cummins for the proven reliability of its generator sets: an imperative considering the mine’s isolated location.

The prime power solution is a fully integrated turnkey solution, designed and built by Cummins, which includes the gas generator sets powered by 91-liter, V18 units with turbocharging and after-cooling, 11 kV switchboard acoustic enclosures and remote monitoring system. A Cummins DMC300 Digital Master Control is used for load demand management.

A major benefit of the QSV91 is that the product is capable of load acceptance steps of 50 percent. This allows the mine loads and mill motors to be quickly reinstated with minimal generators running, providing higher efficiencies as the generator spinning reserve levels are significantly reduced.
