Collect further mid-long term operating experience, starts and hours, under semicommercial conditions
Test sensor data will still be recorded, however test requirements are no longer prime focus
Confirmation of „readyness for commercial service“, based on load regime required by grid operator
Operate by staff w/o special qualification (other than standard GT O&M experience)

Proven efficiency and output – proven economic advantages Voice of the customer: E.ON Energie AG, Germany
Bernhard Fischer Member of the Board of Management E.ON Energie AG, Germany
“
In actual operation, the SGT5-8000H has more than met our high expectations: During roughly 1,200 hours of testing in Irsching, Block 4, we were able to experience the performance of the world’s most efficient gas turbine for ourselves. Expansion is currently under way to a combined cycle power plant. With its commissioning in the year 2011, it will similarly set new standards when it comes to efficiency and output.
