Siemens announced Wednesday it has commissioned the Lunen hard-coal-fired power plant, which went online and has been in continuous operation this month. The plant is owned by Trianel Kohlkraftwerk Lünen GmbH und Co. KG and was built as a turnkey unit under a consortium arrangement between Siemens and IHI Corp.
According to Siemens, the plant has almost 46 percent efficiency and is the cleanest and most efficient hard-coal-fired plant in Europe. The plant can provide electricity for around 1.5 million households and also supplies the city of Lünen with district heating.
The core feature of the plant comprises a model SST5-6000 steam turbine, a model SGen5-3000W generator and the SPPA-T3000 instrumentation and control system.
According to Trianel Managing Director Manfred Ungethüm, the plant will help provide the right balance between power plants delivering constant base load and fluctuating power from renewables required in Germany.
