- Geothermal plants producing electricity would typically require a substation with busbars, switchgear, transformers, circuit breakers, and connection to transmission lines to be able to export their power.
- Binary ORC turboexpander power generators would generate a certain level of voltage that would be transformed up to higher voltages for onward transmission depending on the requirements of the utility grid or distance to private power user.
- The site power generation equipment output rated voltage could be as low as 400V but for medium to large machines it could be between 6.6kV to 11kV. Some large scale systems directly connected to HV grids have been 20kV, 24kV, or even up to 36kV.
- Grid distribution line rated voltages could be from 33kV MV up to 132kV HV depending on the local power demand requirements / characteristics and distances to power users.
- Safety and control systems would help ensure the integrity of all this equipment.
