Description

SIEMENS SGT5-400DLE Gas Turbine – 290–540 MW - 2019

The SIEMENS SGT5-400DLE Gas Turbine, manufactured in 2019, is a robust, high-capacity turbine designed for both simple cycle and combined-cycle power generation. It offers exceptional fuel flexibility, including natural gas, LNG, and liquid fuels, and delivers output ranging from ~290 MW in simple cycle to ~540 MW in combined cycle, depending on configuration.

Featuring a two-shaft design, 15-stage axial-flow compressor, and DLE annular combustion system, the turbine ensures ultra-low emissions and high operational stability. Its combined-cycle thermal efficiency exceeds 60%, and it meets stringent NOx emission standards without water injection, achieving levels as low as 15 ppmvd at 15% O₂.

The SGT5-400DLE is ideal for large-scale grid power plants, CHP stations, or LNG facilities, offering high output, advanced combustion control, and low lifecycle costs.
