103095 - Advanced Turbine Efficiency Package Upgrade for the SGT5-4000F Service Fleet 

In course of the energy transition natural gas as bridging energy source will have a significant importance. Therefore, in the next decades gas turbines also in combined cycle application will play a major role in the energy generation portfolio. As Original Equipment Manufacturer, Siemens Energy, is developing continuously products to adjust its capabilities to the current market requirements. In the present market environment for service fleet it is important to increase gas turbine performance. Out of the worldwide Siemens Energy gas turbine fleet the SGT5-4000F has with its 354 units majorly in combined cycle operation a significant contribution.

To improve our SGT5-4000F customers competitiveness, Siemens Energy offers support in all services especially in reaching their transformation targets towards decarbonization and cleaner energy generation. With the aim of meeting these market requirements, Siemens Energy has developed the advanced turbine efficiency package (ATEP) as upgrade package, focussing on increasing efficiency of currently operating gas turbine power plants. The ATEP turbine blades and vanes were successfully developed based on a multi-point and multi-discipline optimization of the turbine section.  

In doing so, it was possible to further increase in combined cycle application the power output up to 40 MW and to improve the efficiency up to 1.5 %-pts. With this values significant savings of fuel with its related costs go along. Depending on the engine baseline before upgrade implementation exemplarily a annual CO₂ reduction of 30.0000 tons is linked with the ATEP upgrade (iso conditions, 6000h/a baseload). In September 2022 ATEP upgrade was first time successfully implemented at customer site, accompanied with a validation instrumentation and testing program. Performance improvement was successfully demontrated in a first customer engine.

This paper and conference contribution will give technical details on the ATEP upgrade and its implementation.
