Systems and methods for augmenting the power generation capabilities of combined cycle power generation systems by more effectively recovering heat from exhaust gases of peaking cycle gas turbines are provided in the disclosed embodiments. In certain embodiments, the present techniques may include receiving superheated steam from a heat recovery steam generation (HRSG) unit. Heated exhaust gas from a peaking cycle gas turbine may be used to transfer heat to the superheated steam received from the HRSG. The systems used to transfer heat to the superheated steam may include a supplementary superheater located in an exhaust path of the peaking cycle gas turbine. The superheated steam exiting the supplementary superheater may be delivered to a steam turbine of a combined cycle power generation system, where the superheated steam may be used as a power source. Optionally, a peaking cycle attemperator may be used to ensure that the temperature of the superheated steam delivered to the steam turbine does not exceed a predetermined temperature level, thereby protecting the steam turbine and associated equipment.
