Top Use Cases
- Large-scale electricity production (steam or gas power plants): Turbo generators are widely used in major power plants, where a steam or gas turbine spins the generator shaft to produce electricity for the grid.
- Hydropower electricity generation: When water flows through a turbine (e.g. from a dam or reservoir), the turbine drives a turbo generator — converting water’s kinetic or potential energy into electrical energy for supply.
- Combined-cycle power plants for higher efficiency: In some gas-turbine setups, exhaust heat from the turbine is used to produce steam, which then drives a steam turbine connected to a turbo generator — boosting overall efficiency compared to simple-cycle plants.
- Standby or peaking power for variable demand: Turbo generators driven by gas or small turbines can act as standby or peaking plants — powering up quickly when electricity demand spikes or when other plants go offline, ensuring grid stability.
- Captive power for industrial or remote facilities: Factories, hospitals, or remote installations may use on-site turbo-generator units (especially gas-turbine ones) to generate their own electricity — helpful where grid supply is unreliable or unavailable.
- Power for ships or special-purpose installations: Turbo generators also serve in marine or mobile applications (e.g. steam-turbo-electric ships), where turbines drive generators to provide electrical power and propulsion — useful in settings without external grid access.
Recent Developments
- In September 2025, EBARA announced successful operational testing of its electric turbo pump for rocket engines, using actual liquid propellants (LNG and liquid oxygen).
