Siemens H-class Gas Turbine Fleet Exceeds 200,000 Operating Hours

LCG, March 4, 2016--Siemens announced yesterday that its fleet of H-class gas turbines achieved over 200,000 operating hours in January 2016. Today there are 19 turbines in the SGT-8000H series in commercial operation.

The H-Class gas turbines, which have increased power output from the earlier F-Class turbines, have a gross power output of 296 MW. The high-efficiency gas turbines can achieve efficiencies greater than 60 percent in combined cycle power plants.

The head of Large Gas Turbines and Generators in the Siemens Power and Gas Division stated, "The SGT-8000H achieves a very high degree of efficiency and is marked by short startup times and fast load-changing capabilities. 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 percent, and availability is over 96 percent."

The first SGT5-8000H (50-Hz) gas turbine began commercial operations in 2011 in Germany, with the next SGT6-8000H units for the 60-Hz market following in 2013 at Florida Power & Light's Cape Canaveral power plant in Florida, U.S. and the Dangjin 3 plant in South Korea.

Siemens has now sold a total of 76 H-class gas turbines worldwide, and Siemens states that this makes it the most successful gas turbine in this efficiency category on today's market. Worldwide Siemens has sold 39 of the turbines on the 50-Hertz (Hz) market and 37 turbines on the 60-Hz market. The most recent order for two H-class turbines came from Mexico in January 2016 for the CFE Empalme II combined cycle plant.
