Finland’s Wärtsilä is to supply engines, generators and associated auxiliary equipment to a power plant serving an iron ore mine in Western Australia.

The six 20-cylinder Wärtsilä 34DF engines selected for the project offer 50 MW of dual-fuel capability, giving the mine the option to use either natural gas or light fuel oil.

The contract was signed in July with Fortescue Metals Group Ltd, one of the world’s leading producers of iron ore. The power plant is needed to supply electricity for its Solomon Hub mine, which is part of the company’s expansion in the Pilbara region of Western Australia. The Fortescue Solomon Phase I project is scheduled to be in commercial operation by the third quarter of 2012.

Together with the six Wärtsilä engines, the first Wärtsilä dual-fuel engines to be installed in Australia, the power plant utilizes two gas turbines, primarily operating in constant power mode. The engines have the capability to handle the necessary fast stops and starts and variations in load, while maintaining high efficiency levels.
