Method for improving the combination between a gas turbine and a steam cycle with an another non fossile source of primary energy, consisting in recycling part of the residual heat of exhaust gases from the gas turbine (5) in order to reheat at intermediate pressure the main flow of the steam cycle. In order to complete the recycling, the remainder of the residual heat is used to heat liquids and, usually, steamings at maximum pressure of the cycle or at the characteristic intermediate reheating pressure. The steam cycle may be a water vapour cycle or a steam cycle which is a mixture of water and a less volatile fluid which vaporizes at the characteristic intermediate reheating pressure.
