Gas power plants

Wärtsilä gas power plants use natural gas, the cleanest fossil fuel available, in the most economical way. This is possible thanks to their high efficiency at any load and unbeatable flexibility to start and stop exactly according to needs.

Besides the combination of efficiency and flexibility, these gas power plants also offer low emissions, and can provide a great amount of power in a reduced site, making it the optimal solution for locations where minimizing the environmental impact is a priority. As such, they can be placed close to consumption nodes, optimizing the power system.

Wärtsilä gas power plants can run on natural gas, LPG and various biogases.

The benefits

  • Plant electrical efficiency of up to 50% in simple cycle and 54% in combined cycle mode
  • Only 5 bar gas pressure requirements for operation, which means no gas compressor is needed at the plant
  • Lean-burn technology guarantees very low emissions by itself, complying with most regulations, including IFC (World Bank group).
    By adding an SCR (selective catalythic reduction) unit, even the most stringent standards worldwide can be met.
