History

The power plant with 1 power generation line of 60 MWel (50 Hz) was commissioned in 1967 in Western Europe and shut down in 2008, after approx 230,000 operating hours. The plant design was for base load with local lignite fuel. In 1985 the steam turbine was equipped with a 0 - 100 % extraction for 114 °C / 80 °C district heating for up to 20 MWth. In 1997 the power plant was modified and refurbished to use Anthracite (hard coal), the power output increased from 60 to approx 70 MWel. At the same time, some new components have been installed (e.g., coal mills).
