Gold mine

McArthur River Mine

Northern Territory, Australia

53 MW

The McArthur River Mine in Australia, is one of the world’s largest providers of zinc in bulk concentrate form. Global energy producer EDL is responsible for supplying power to the mine. Wärtsilä has been a trusted partner for EDL for many years now, delivering gas engines and providing lifecycle services for condition-based maintenance to the power plant. The end result is better fuel efficiency, a low levelised cost of electricity, lower OPEX and guaranteed availability.

EDL is committed to delivering on our customers' expectation for reliable, cost-effective and environmentally sustainable energy and Wärtsilä's approach should help us achieve this. We expect the new agreement will help us to increase efficiencies, which in turn benefits our customer with greater reliability and reduced downtime.
