A hybrid-electric propulsion system (100) includes a motor drive (102) and a rechargeable energy storage system (104) electrically connected to the motor drive. A gas turbine engine (106) is operatively connected to the motor drive (102) and the rechargeable energy storage system (104). An emergency power source (108) is operatively connected to the motor drive (102). The emergency power source (108) is a primary battery (120) in electrical communication with the motor drive (102). A method for providing emergency power to a hybrid electric propulsion system (100) includes determining whether one of a main engine power source and a rechargeable energy storage system (104) are available for powering a motor drive (102). The method includes initiating a primary battery (120) for powering the motor drive (102) if the main engine power source and the rechargeable energy storage system (104) are unavailable.
