Abstract: Mobile power generation system and methods for dual-voltage generation include providing a trailer including a rear end, a front end, a bottom end, and a top end, a gas turbine housed inside the trailer, and an electrical generator coupled to the gas turbine to generate electricity and housed inside the trailer. The electrical generator is at least a dual-voltage generator configured to provide an auxiliary power to generator parasitic loads and a main primary load output power and comprising one or more taps configured to provide the auxiliary power to generator parasitic loads. The electrical generator is at least a dual-voltage generator comprising three-phase circuitry including three lines and one or more taps configured to provide auxiliary power to generator parasitic loads, ends of the three lines configure to provide a main primary load output power.
