Siemens commissions high efficiency steam power plant

World Coal,

The Lünen hard-coal-fired power plant, built as a turnkey unit by Siemens and IHI Corporation, has been on line in continuous operation since the beginning of December.

The plant, owned by Trianel Kohlkraftwerk Lünen GmbH und Co. KG, has an installed electrical capacity of 750 MW. With 7000 full load operating hours forecast for next year, the Lünen plant has the capacity to provide electricity for approximately 1.5 million households. It also supplies the city of Lünen with district heating. With an efficiency of almost 46%, Lünen is the cleanest and most efficient hard-coal-fired power plant in Europe. Using Siemens technology the plant is able to save up to a million t of CO2 every year.

The Lünen power plant is located on the Datteln-Hamm Canal in northwest Germany. The core feature of the plant comprises a model SST5-6000 steam turbine, a model SGen5-3000W generator, the complete electrical installations, and the SPPA-T3000 instrumentation and control system. The SST5-6000 high-performance steam turbine guarantees highly efficient operation in base load and is also ideally suited for highly responsive ramping.

"Despite difficulties arising from the special licensing situation for coal-fired power plants in Germany, we have managed to build a plant to the highest technical standards that by far surpasses the contractually agreed performance values for output and efficiency," explained Rainer Hauenschild, CEO of the Energy Solutions business unit at Siemens Energy.

"The energy transition in Germany we need the right balance between power plants delivering constant base load and fluctuating power from the renewables," added Manfred Ungethüm, managing director of the Trianel power provider. "The high-efficiency coal-fired power plant in Lünen is a mainstay of the energy mix in the state of North-Rhine Westphalia. The power from this plant is in demand."
