1. A system for powering equipment used in a hydraulic fracturing operation, the system comprising:
at least one first generator in electrical communication with a first switchgear for providing power to primary components of a hydraulic fracturing operation;
at least one second generator in electrical communication with a second switchgear for providing power to backup components of a hydraulic fracturing operation; and
the at least one first generator being independent of the at least one second generator so that if the at least one first generator loses the ability to generate electricity, the at least one second generator can continue to generate electricity;
wherein the first and second switchgear channel electrical power from the at least one first generator and the at least one second generator, respectively, to a transformer.
