A gas turbine electric powerplant, preferably driven by an aeroderivative turbine engine of split shaft design. The gas turbine engine is coupled to a speed reducer, which is in turn coupled to an electric generator. An engine mount is provided that ensures that the gas turbine engine will remain in proper alignment with the speed reducer and generator, even during the thermal expansion or contraction thereof. Preferably, the components comprising the powerplant are mounted to a common, transportable base, so that the powerplant can be delivered to various locations. An overspeed control system is provided for ensuring that a runaway condition of the gas turbine engine does not occur should the gas turbine engine become disconnected from the speed reducer or generator. Sensors are used to monitor multiple operating conditions of the powerplant. A microprocessor-based control system communicates with the sensors, and is further adapted to activate the overspeed control system if an overspeed condition is detected.
