Abstract: The present application provides a combined cycle system. The combined cycle system may include a number of gas turbine engines, a number of heat recovery steam generators with a selective catalyst reduction and/or oxidation catalyst system, and a catalyst heating system. The catalyst heating system directs an extraction from a first gas turbine engine of the number of gas turbine engines to the selective catalyst reduction and/or oxidation catalyst system of a second heat recovery steam generator of the number of heat recovery steam generators.
