Siemens H-class gas turbines achieve one million operating hours

The SGT-8000H turbine's high combined cycle efficiency in conjunction with its maturity and reliability is especially valuable in metropolitan areas and countries with rapidly growing energy requirements like Mexico, Egypt, and Malaysia. The SGT-8000H achieves low NOx emissions over a wide load range, and is also highly flexible, thanks to its load-following capability of 60 MW/minute (SGT6-8000H for 60Hz)/ 80 MW/minute (SGT5-8000H for 50Hz). This makes the turbine ideal for simple cycle peaking applications as well. These operational flexibility features help balance the grid, which is becoming a challenge due to the increasing share of volatile renewable sources. The turbine can be also used in a combined heat and power plant (CHP). An example is the CHP at the location Lausward in Germany. There the overall fuel efficiency of the natural gas used thus climbs up to 85 percent.
The H-class is used worldwide: for example, many turbines are installed in the U.S. and Southeast Asia. With their rapidly growing energy requirements in small geographic areas, the tiger economies (South Korea, Republic of China (Taiwan), Singapore and Hong Kong), in particular often opt for the H-class. South Korea alone is operating 15 of the SGT6-8000H gas turbines.
A significant increase of the SGT-8000H fleet size was achieved by the win of the largest single order in Siemens history. In 2015, the Egyptian Electricity Holding Co. (EEHC) ordered 24 H-class gas turbines. In just 27 months, the turbines were installed in combined cycle power plants (CCPPs) in Beni Suef, Burullus, and New Capital. Siemens also served as the general contractor (EPC).
In 2017, Siemens launched its HL-class gas turbine, which builds on the proven design and the operating experience of the Siemens H-class. With a series of new, but already tested technologies, like super-efficient internal cooling features for blades or vanes and an advanced combustion system, these large machines achieve a CCPP efficiency of more than 63 percent. The power output of the 50Hz version is 593 MW. The 60Hz version of the HL-class with 405 MW, the SGT6-9000HL, has already been sold twice. The first 50Hz machine, a SGT5-9000HL, will be installed in the United Kingdom. The machines are currently in manufacturing process.
