Shown here is the SGT5-8000H gas turbine installed at the Irshing 4 plant. The Irsching test
center is property of Siemens and will remain so until the end of the combined-cycle test,
when the whole plant will be handed over to E.ON, which will run it as a regular power gen-
eration section of the Irsching power plant.
Official Launch of Siemens’
375 MW Gas Turbine
The June 2008 issue of Diesel & Gas
Turbine Worldwide reported the start of
the full-load test program of the SGT5-
8000H gas turbine. Rated at 340 MW,
this marked the beginning of the validation test at the Irsching 4 test center.
After 1500 fired hours and 174
starts, Siemens officially launched the
new product, rated 375 MW in simple-cycle and 570 MW in a single-shaft
combined-cycle configuration.
These figures are substantially higher
than the ones announced by the com-
pany at the start of the program. “No
surprise for us,” said Willibald J.
Fischer, project manager for the SGT5-
8000H. “These are the design figures
confirmed by the validation test. In the
past, we indicated lower figures to have
some margin, just in case, but now that
the turbine has been running up to
around 400 MW for testing purposes,
the 375 MW output is our official
introduction figure.”
The H class gas turbine is the first
frame developed since the merger of
Siemens and Westinghouse, combin-
ing features of the two established
product lines for 50 and 60 Hz grids.
This turbine was developed in strict
compliance with the company’s prod-
uct developing process using “Design
for Six Sigma” tools. The target was set
to deliver a competitive product
focused on low life-cycle cost, high per-
formance in combined cycle, good
serviceability, high flexibility, reliability
and low emissions.
