A hybrid electric propulsion system 100 includes a gas turbine engine 102 and an electric machine 162 coupled to the gas turbine engine 102. A method for operating the propulsion system 100 includes determining, by one or more computing devices 410, a baseline power output for the gas turbine engine 102; operating, by the one or more computing devices 410, the gas turbine engine 102 to provide the baseline power output; determining, by the one or more computing devices 410, a desired power output greater than or less than the baseline power output; and providing, by the one or more computing devices 410, power to, or extracting, by the one or more computing devices 410, power from, the gas turbine engine 102 using the electric machine 162 such that an effective power output of the gas turbine engine 102 matches the determined desired power output.
