Siemens Energy's H-class technology has been proven through extensive testing
Simple Cycle Power Generation (ISO)
Combined cycle efficiency: 61%
Powerful gas turbines for efficient combined cycle applications
SGT5-8000H is the first air-cooled H-class gas turbine on the market. With over 1.5 million hours of operating experience, it has become the most reliable H-class gas turbine technology available today.
The simple cycle power output is 450 MW, or the combined cycle operating power output is 665 MW, with a combined cycle efficiency of 61%. It is one of the most efficient and powerful gas turbines in commercial operation, with low operating and lifecycle costs.
Powerful and highly flexible in functionality
In combined cycle operation, the SGT5-8000H gas turbine can provide a power output of 665 MW and an efficiency of 61%. The internal cold air passage from the compressor to the turbine ensures rapid thermal response of the rotor during high load transients and rapid cold start conditions. A gas turbine designed specifically for fast start-up and high flexibility.
Convenient factory integration
SGT5-8000H can be easily integrated into single axis (SCC5-8000H 1S) or multi axis (SCC5-8000H 1x1 and 2x1) combined cycle equipment.
Our proven unit and factory concepts adopt standardization, pre assembly, and pre packaging to minimize the need for pipeline manufacturing during on-site assembly and construction. This can easily install the turbine and shorten the project duration.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
