An Integrated Solar Combined Cycle Plant (ISCC), consists of the installation of a conventional combined cycle (CC), with a gas turbine and a steam turbine where the heat recovery and steam generator system  (HRSG) is connected to a solar field .

The fuel is usually burned in the combustion chamber of the gas turbine. The steam generated in the solar field is incorporated into the water-steam cycle of the CC plant, increasing the steam generation capacity and therefor boasting the production capacity.
