request info call 303-809-1189 3 available now
The Siemens SGT-PAC 4000F is a complete 50 Hz heavy-duty gas turbine generator package built around the proven F-class engine platform, delivering roughly 280–330 MW in simple cycle. Supplied as a turnkey block, the package integrates the gas turbine, air-cooled generator, static starting system, controls, and full auxiliaries on structural skids for rapid site installation.
It is engineered for utility-scale simple-cycle peaking, baseload combined-cycle power plants, and industrial cogeneration duties on 50 Hz grids, with proven dual-fuel capability on natural gas and liquid backup fuels.
Why aren’t we more specific about price/quantity/source? Most of the generators we offer are from companies that need to unload their equipment quietly, because of canceled projects or failed financing. They only allow us to list them on the condition that we not display identifying information. More details are available — contact us.
Core Characteristics
- Power Output: Simple-cycle net output typically 280–330 MW at generator terminals depending on variant and site conditions.
- Frequency: 50 Hz three-phase synchronous machine designed for direct grid connection without an intermediate gearbox.
- Fuel Type: Dual-fuel capability on natural gas and light distillate liquid fuel with online changeover.
- Net Efficiency: Simple-cycle efficiency near 39–40 percent, rising above 58 percent in combined-cycle configuration.
- Heat Rate: Simple-cycle heat rate typically in the range of approximately 8,600 to 9,000 kJ/kWh.
Design & Performance
- Industrial Duty: F-class heavy-frame construction with disc-type rotor, Hirth serrations, and central tie bolt for durability.
- Fuel Flexibility: Annular combustor with hybrid burners supports natural gas and distillate operation with low NOx emissions.
- Modularity: Delivered as pre-assembled skid-mounted blocks covering turbine, air-cooled generator, controls, and full auxiliary systems.
- Operational Track Record: In service since the late 1990s with hundreds of units deployed and fleet reliability exceeding 99 percent.
