Siemens H-class gas turbines have exceeded 200 000 operating hours

The fleet of Siemens H-class high-efficiency gas turbines achieved more than 200 000 operating hours in January 2016. There are currently 19 turbines in the SGT-8000H series in commercial operation. Siemens has sold a total of 76 H-class gas turbines worldwide to date.

The most recent order for two H-class turbines came from Mexico in January 2016 for the?CFE Empalme II combined cycle plant. The SGT-8000H turbines are manufactured in Berlin, Germany, and Charlotte, US and shipped from these locations to sites around the globe.

The first SGT5-8000H gas turbine entered commercial operation in 2011 in Irsching near Ingolstadt, Germany, with the next SGT6-8000H units for the 60-Hz market following in 2013 at the Cape Canaveral power plant in Florida, U.S. and the Dangjin 3 plant in South Korea. Siemens is investing its expertise acquired from 200 000 operating hours, or roughly 23 years of operation, in the continuous development of the H-class machines.

“The SGT-8000H achieves a very high degree of efficiency and is marked by short startup times and fast load-changing capabilities,” said Theo Maas, Head of Large Gas Turbines and Generators in the Siemens Power and Gas Division. “The turbines have proven themselves extensively in daily power plant operation after more than 200 000 hours of operation: The reliability of the SGT-8000H fleet is over 99%, and availability is over 96%.”

Combined cycle power plants equipped with SGT-8000H gas turbines achieve an efficiency level of over 60%. The Lausward combined cycle plant at the Düsseldorf port has set three new world records at once. The plant is also able to provide 300 MW(th) of heat for the city of Düsseldorf’s district heating network. The installation of an H-class gas turbine in this kind of combined heat and power plant (CHP) has proven to be one of the most efficient ways to convert fuel into usable energy. The high fuel efficiency of the plant plays an important role in meeting economic requirements and reducing the environmental impact.
