Combined power augmentation system and method

An electrical generation system including a first gas turbine (324) and a heat recovery steam generator (330) coupled to the gas turbine and including high pressure super-heater (318) having a high pressure super-heater output. The electrical generation system also includes a second gas turbine (306), an output duct (308) coupled to the second gas turbine and a supplemental high pressure super-heater (312) within the output duct and thermally coupled to the high pressure super-heater output.
