Siemens Energy has developed a new steam turbine with a capacity of up to 120 MW for use in geothermal power plants.

The SST-500 GEO follows the SST-400 GEO turbine, which was introduced in the autumn of 2011, and is a single-casing, double-flow condensing machine.

The company said each unit is tailored to particular resource conditions by adapting the blade path within the standardized casing and can function in temperatures of up to 250°C and steam pressures up to 15 bar.

Siemens Energy Industrial Power Business Unit chief executive Markus Tacke said: “The SST-500 GEO will enable us to participate in the geothermal growth we currently see in regions such as the eastern coast of Asia, the western coast of the Americas and parts of Africa.”

Siemens Energy will have a booth at the GEA Expo run in conjunction with the GRC Annual Meeting, Sept. 29-Oct. 2 at the MGM Grand, Las Vegas, Nevada.
