The 60MW turbine combines the proven casing and turbine-generator package of the Siemens SST-400 steam turbine with the steam path technologies developed, tested and applied by the steam turbine service provider TurboCare.

The Siemens steam turbine can be deployed in geothermal power plants with different thermal fluids.

Live steam temperatures up to 250°C and steam pressures up to 12 bar absolute will be suitable for the steam turbine and it includes resource and turbine stage-specific high-grade materials and moisture removal features.
