The cogeneration plants producing electricity and steam, also known as CHP (combined heat and power) plants, are designed for a nominal power-to-steam ratio. This means that the most efficient operation of the gas turbine-based cogeneration is in the base load mode. In this mode, the gas turbine operates at full load and all available exhaust heat is absorbed in a heat recovery steam generator. The generated steam is used for the bottoming power cycle and for the industrial process. Recently, many cogeneration plants have been installed in the US which contribute, with their power production, to the electric utility grid. Although the responsibility for the frequency control of the electrical grid lies with the electric utilities, the proliferation of the base-loaded cogeneration plants makes this task very difficult and forces large utility plants into cycling service. Some electric utilities recently have requested the cogenerators to provide a plant design which allows the plant cycle or to be electrically dispatched in response to the grid demand. In response to this need, Fluor Daniel is designing a gas turbine-based cogeneration plant capable of delivering anywhere from 0 to 100% of design electrical power output while maintaining an uninterruptible steam supply to the adjacent industrial plant.
