The cost efficiency comes not only from the generation of electricity, which can be used to reduce the expense of purchased utility power, but also from the fact that the generated steam is used twice. This waste fuels a boiler to generate steam. The high-pressure steam drives a turbine generator set that in turn produces electricity. The low-pressure steam output from the turbine can be used for a variety of process purposes.
