The Wärtsilä 50 is a four-stroke diesel engine generating set. High efficiency and power on any liquid fuel combined with high reliability and flexibility makes this solution perfect for flexible baseload applications including daily starts and stops. The dynamic features of the genset are also suitable for balancing power generation, especially in larger power plants where footprint needs to be reduced.
Wärtsilä 50 engine comes in 18V cylinder configuration producing up to 18.9 MW
electrical power. It uses direct fuel injection that results in high engine efficiency while
keeping emissions within limits set by the World Bank/IFC Guidelines.
