Finnish power plant to overhaul gas turbine

A power plant in Finland is to rebuild its gas turbine control system to increase its reliability.

Vantaan Energia (VE) will work with process technology provider Metso to replace the existing turbine control system that has reached the end of its life cycle at Martinlaakso.

The project will include overspeed and vibration protection for the turbine, plus changes to turbine hydraulics, among other things.

VE is one of Finland's largest urban energy companies and is owned by the cities of Vantaa (60%) and Helsinki (40%). The Martinlaakso power plant produces about two-thirds of VE's electricity output and most of its district heat. The total electrical capacity of the plant is about 195MW and thermal capacity is 330MW.

The rebuilt control system will be operational in November 2013.
