Gas Power Plant 52.3 MW with 6 x Wartsila 20V34SG gas generators and heat recovery steam boilers 

The main equipment was delivered and commissioned by Wartsila in year 2006 and today the units have approx 40 000 - 50 000 operating hours depending on unit. The equipment is in good operational condition but the engines need a 46 000 hour overhaul.

Generators are installed on common base frame with the engines and common base frame is isolated from the foundation by flexible mounting with steel springs. Most of the auxiliaries are in the factory built in large new type modules which enable easy relocation of the equipment. 

The engines are of the four stroke, lean burn, pre chamber, spark ignited, port injected, trunk piston, turbocharged and intercooled design. The engine automation is a complete embedded management system, integrated with an engine control system for electricity controlled fuel injection. The control system is distributed bus based system where monitoring and control function is placed close to measuring and control point. This leads to less wiring and improved performance. The engines are designed for continuous operation in gas mode in island mode at any load between 40 -100% of nominal power
