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.

CSP Integration with natural gas combined cycles is an attractive alternative to generate base load electricity with a greener footprint.
