21 December 2007 - First firing of Siemens SGT5-8000H, the world's largest and most powerful gas turbine, was achieved as scheduled on December 20, 2007. This marks the beginning of a planned 18-month trial operation period at the E.ON Irsching 4 power plant near Ingolstadt.
After successful completion of trial operation, Siemens will expand the plant to a high-efficiency combined-cycle power plant (CCPP) with a total output of about 530 megawatts and a peak load efficiency of over 60 per cent. Handover of the CCPP to E.ON Kraftwerke, a subsidiary of E.ON Energy, is expected to be made in 2011. E.ON and Siemens are investing a total of approximately €500m ($717m) in this endeavour.
"Climate change is one of the greatest challenges of the 21st century. Consequently the objective is to not only meet the continuously increasing demand for electrical energy reliably and economically, but above all in a manner that is climatically-compatible," said Dr. Uriel Sharef, member of the board at Siemens AG. Energy. Efficient, innovative products such as our new gas turbine play an instrumental role in this. "With E.ON, we have landed a strong partner for this pioneering project in Irsching. Together we underscore our claim to technological leadership in the energy industry in Germany and worldwide," Sharef added.
Dr. Klaus-Dieter Maubach, chairman of the board at E.ON Energie AG, pointed out the significance of further technological development in power generation: "Combating climate change has become one of the cardinal challenges in our business. E.ON is planning investments totaling 60 billion euros by 2010. The major part of this will be in new and environmentally benign generating capacities. The Irsching location is an outstanding example of this: Irsching 4 will achieve an efficiency of over 60 percent, in itself a quantum leap in power plant engineering. As a result, this power plant will emit approximately 40,000 tons of CO2 per year less than existing plants. In addition, we are investing in the latest technology for our advanced coal-fired power plants now under construction, and also for the renewable energy sector".
