Wärtsilä has been awarded contracts to supply two power plants to be installed at nickel facilities in the Madang region of Papua New Guinea.

The plants are to be equipped with exhaust gas heat recovery systems with the waste heat being utilized in the complex refinery process. Both installations are scheduled to be completed before the end of 2009.

The orders, placed by China ENFI Engineering Corporation, will see one plant located at the Ramu nickel mine, and the other at the nickel refinery in the port area.

The Ramu nickel mine is being developed by the China Metallurgical Group (MCC), a Chinese state-owned mining and natural resources exploitation concern, and its partners.

The combined output of the two power stations will be in excess of 90 MWe and will supply electricity to the entire nickel mining and refining project facilities.

Wärtsilä is contracted to supply the equipment together with an engineering and technical assistance package. Because of the remote location of the installations, the power plants will be installed with some spare capacity.
