The growing global demand for clean and sustainable energy has prompted the development of sophisticated power generation technologies that can improve efficiency while reducing environmental effects. In this context, the combination of various thermodynamic cycles, such as gas turbines and organic Rankine cycles (ORC), with renewable energy sources shows enormous promise for increasing overall system performance. A combination of these technologies, particularly parametric optimization, can provide a more efficient way to use available resources, especially when powered by solar energy. The present paper studies the performance evaluation of an intercooled gas turbine with an ORC and a solar-assisted steam turbine for power generation. The ORC is used to intercool the gas turbine, and solar energy is utilized to augment steam generation in waste heat recovery from gas turbine exhaust. We carry out the mathematical modelling of the proposed cycle based on the laws of thermodynamics. The study reported that the thermal efficiency of a hybrid cycle is 61.87% at a gas turbine inlet temperature of 1500 K.
