As good as new: Siemens to modernize steam power plant in North Rhine-Westphalia
The Siemens Power Generation Group (PG) under contract to RWE Power AG is to modernize the Niederaussem steam power plant in North Rhine-Westphalia. Thanks to advanced turbine technology the plant’s CO2 emissions will be reduced by 600,000 t per annum with the same amount of electricity being generated.
Siemens PG is to upgrade the high- and intermediate-pressure turbines and two low-pressure turbines at the 620-MW coal-fired power plant units G and H in Nied-eraussem, which went on line in the mid-1970s. The turbines will be equipped with new advanced rotors and blading. The scope of services will include further efficiency-enhancement measures such as modernization of the condensers and the turbine I&C systems. The special high-precision components with a total weight of approximately 400 metric tons will be produced at the Siemens turbine manufacturing plant in Muelheim; the condenser modules measuring 3 x 6 x 8,50 meters and weighing 70 metric tons are the largest components involved. Modernization work is slated for completion in 2008 and 2009.
“Compared to new construction projects older power plants can be adapted more rapidly to future market conditions through customized modernization packages,” explained Harald Griem, head of the Service Product Line at Siemens Power Generation. “These measures not only increase plant efficiency and availability but also enhance operating economy and environmental friendliness.”
The Power Generation Group (PG) of Siemens AG is one of the premier companies in the international power generation sector. In fiscal 2006 (which ended September 30), Siemens PG posted sales amounting to more than EUR10 billion and received new orders totaling EUR12.5 billion, according to U.S. GAAP. Group profit amounted to EUR782 million. On September 30, 2006, PG had a work force of approximately 36,400 worldwide.
