Siemens Energy : Irsching 5 Combined-Cycle Power Plant, Germany

On May 17, 2010, after around two years of construction, the Irsching 5 combined-cycle power plant near Ingolstadt, Germany, was put into operation in an official ceremony. The owner of the new plant is Gemeinschaftskraftwerke Irsching GmbH (GKI), a project company consisting of E.ON Kraftwerke GmbH, N-ERGIE AG, Mainova AG and HEAG Südhessische Energie AG. E.ON Kraftwerke is responsible for plant operation.

Siemens built the 847 MW (net) plant as a turnkey project. “With its high efficiency level, and the associated low emissions, along with its short start-up times, this plant sets new standards for this performance class,” said Michael Suess, CEO of the Fossil Power Generation Division of Siemens Energy.

This new natural gas-fired plant is equipped with two SGT5-4000F gas turbines, one SST5-5000 steam turbine, three hydrogen-cooled generators with electrical systems and the SPPA-T3000 I&C system from Siemens. Thanks to its F-class gas turbine technology and the quadruple-flow low-pressure steam turbine, this plant now achieves an efficiency level of more than 59.5%, thus minimizing its CO2 emissions. The stateof-the-art burner technology used at the plant also keeps NOx emissions at a low level (<15 ppm). Irsching 5 is designed for 250 starts annually.

The plant reaches its full output in only 30 to 40 minutes to account for the more stringent grid requirements with regard to the integration of wind power. Combined-cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2010, revenue from the Portfolio totaled about US $36.7 billion (E28 billion).
