SGT5-8000H

Siemens Power Generation expands its product portfolio with the new, innovative 340+ MW gas turbine SGT5-8000H, featuring advanced H-class efficiency.

This innovative gas turbine is characterized by:

High efficiency
Low life-cycle costs
High reliability and availability
Operational flexibility
Low emissions

The world-class gas turbine combines the best features of the existing product lines and technology advancements. It will be the primary driver of the single-shaft SCC5-8000H combined cycle power plant, which will have an output of 530+ MW and an efficiency level exceeding 60%.

Technical features

H-class, 60% efficiency in combined cycle mode
Fast start-up and cycling capability to support intermediate load requirements
Improved turndown capability for high efficiency and low emission part-load operation
Reduced complexity as an air-cooled engine and parts leading to lower maintenance and operating costs
Advanced materials to increase firing and exhaust gas temperatures
Advanced sealing system for low leakage cooling air

Latest News

The completion of the SGT5-8000H 1st Fire in December 2007 and 1st Synchronization in March 2008 were successfully completed.
The testing program will continue with additional runs through May, with the next regular outage planned for completion in July of this year. The validation Program will continue with a series of planned tests and inspections where results are documented, analyzed, and deviations corrected in a controlled process. Improvements in part design will be installed and the unit subsequently tested in a commercial configuration.
Further testing will continue on and beyond the sales release, scheduled for August 2008. To validate the engine durability and reliability testing will continue until June 2009.
