How it works

How gas turbines produce electricity

To generate electricity, the gas turbine heats a mixture of air and fuel at very high temperatures, causing the turbine blades to spin. The spinning turbine drives a generator that converts the energy into electricity.

The gas turbine can be used in combination with a steam turbine—in a combined-cycle power plant—to create power extremely efficiently.
