Siemens celebrates H-class gas turbine milestone

Siemens is celebrating a milestone as its H-class gas turbine has exceeded one million fired hours of commercial operation.

There are now 70 turbines in operation on four continents, with the output rating of the SGT5-8000H having grown from 375 MW to 450 MW since its launch a decade ago.

Siemens said in a statement today that the SGT-8000H turbine’s high combined-cycle efficiency “is especially valuable in metropolitan areas and countries with rapidly growing energy requirements like Mexico, Egypt, and Malaysia”.

Indeed, Egypt accounted for a boost in the SGT-8000H fleet size when, in 2015, the Egyptian Electricity Holding Co ordered 24 H-class gas turbines – Siemens’ biggest ever single order. Some 27 months later, the turbines were installed in combined cycle power plants in Beni Suef, Burullus, and New Capital.

Elsewhere, the SGT-8000H is deployed in a state-of-the-art combined heat and power plant in Lausward, Germany, where the overall fuel efficiency of the natural gas used is up to 85 per cent.

In Asia, Siemens said that “with their rapidly growing energy requirements in small geographic areas, the tiger economies of South Korea, Taiwan, Singapore and Hong Kong often opt for the H-class. South Korea alone is operating 15 of the SGT6-8000H gas turbines.”
