Dec. 8, 2003 — Wärtsilä Corporation has been awarded a contract by PT Aneka Tambang Tbk (Antam) of Indonesia to supply a 102 MW diesel power plant for its ferronickel smelting plant at Pomalaa in South East Sulawesi, Indonesia. The value of the new order is 64.5 million US dollars.
The power plant will have six 17 MWe generating sets, each powered by a Wärtsilä 18V46 diesel engine. Initially the plant will run on heavy fuel oil and can be converted to run on natural gas at a later stage. The capability of converting the Wärtsilä engines to run on natural gas was an important factor in the choice of Wärtsilä for the new plant.
The diesel power plant is being supplied under an Engineering, Procurement and Construction (EPC) contract. It is the intention of Antam that the plant will then be operated by Wärtsilä under a separate Operating and Maintenance (O&M) contract.
The power plant is being installed as part of a major expansion project. The site currently has two ferronickel smelters and work has begun on building a third smelter. The first three generating sets are to be handed over in 14 months, at the beginning of 2005, and other three in 18 months so that the plant will be fully commissioned in the first half of 2005. After the first stage, the first three sets will supply power to the two existing smelters. When completed the new power plant will supply power to all three smelters.
The smelting plant has an independent electricity system. There are already two existing diesel power plants with a combined output of about 50 MWe. As they are mostly running on light fuel oil (LFO), some of the older generating plant will only be used as stand-by after the new plant is installed.
Wärtsilä Corporation is a global ship power supplier, and is also a major provider of solutions for decentralized power generation and of supporting services.
Wärtsilä provides power plants for baseload, peaking, and combined heat and power applications. Wärtsilä also supplies solutions for gas compression and for oil and gas pumping. The product range comprises gas- and oil-fired power plants with outputs from 1 MW to 300 MW and bio power plants with outputs from 1 to 10 MWe as well as bio thermal plants from 3 to 20 MWth.
Wärtsilä is headquartered in Helsinki with representatives in more than 60 countries. Production facilities are located in Finland, Norway, France and Italy with assembly plants in Spain, USA and India.
Wärtsilä supplied more than 1,400 MW of power to plants around the world in 2002.
