Wärtsilä has received contracts from three Brazilian independent power producers (IPPs) to provide conversions for their generating stations. The conversions will enable them to attain fuel flexibility and switch from heavy fuel oil (HFO) to gas operation.
The combined value of the three contracts, which were received in January 2009, is in excess of EUR 48 million. These combined plant conversions represent the biggest project of its kind ever undertaken by Wärtsilä Services. The converted plants are expected to be fully operational in October 2010.
In addition to the engine conversions, the scope of the contracts includes the installation of the main gas fuel system equipment and the gas compressor units, and the modification of the control and electrical systems. The electrical output from the plants will remain the same whether they run on HFO or gas. Furthermore, the fuel sharing system allows the engines to run on gas and liquid fuel in different proportions. This will optimize the operation of the plants according to the availability of the fuels.
