Reconfigurable turbine for geothermal energy production

A method comprising:

• operating a turbine at a location in a power system using a first fluid having a first composition, wherein the turbine includes a first impeller having a first impeller configuration;
• operating the turbine with the first impeller using a second fluid having a second composition different from the first composition;
• removing the first impeller from the turbine while the turbine remains in situ at the location;
• installing a second impeller in the turbine while the turbine remains in situ at the location, wherein the second impeller has a second impeller configuration different from the first impeller configuration;
• and
• operating the turbine with the second impeller using the second fluid.
