A hybrid concentrated solar combined cycle (CSCC) power plant based on solar reforming technology, method of generating electricity using the system and a solar reformer for use in the system are provided. The system enables integration of a concentrated solar power plant (CSP) and a combined cycle gas turbine (CCGT) power plant, resulting in a hybrid system that corrects known issues related to large-scale concentrated solar power generation. The solar reformer provides for the storage of solar energy in a reformate fuel during the reforming reaction and subsequent release through a gas turbine combustion reaction. Fuels directed into the gas turbine power plant can be alternated between hydrocarbon fluid and the reformate fuel dependent upon available solar thermal energy.
