In 2008 Termelétrica Viana SA ordered a turnkey power plant comprising 20 Wärtsilä 20V32 engines giving 175 MW of installed electrical capacity and 170 MW of net electrical generation.
The Viana project is controlled by a Brazilian Private Equity Fund managed by BTG Pactual, who also owns another power plant in Brazil with five Wärtsilä 18V46 generating sets.
The Viana power plant burns high viscosity heavy fuel oil and is connected to the main national grid. Construction started in October 2008 and the plant was commissioned at the end of 2009. Wärtsilä also has a full operations & maintenance agreement to operate and maintain the Viana plant for 5 years after its completion.
The Viana installation is operated in hot stand-by mode with short notice switchover capability to baseload operation.
Contributory factors in Wärtsilä winning the power plant contract was the high total efficiency provided by Wärtsilä’s engines and Wärtsilä’s ability to provide a total power solution including turnkey delivery and full operations and maintenance of the plants after delivery.
