1. A method for performing hydraulic fracturing using power from a utility electric grid, comprising:
accessing power from the utility electric grid;
operating at least two transformer units, in parallel, to step down a line voltage of the power from the utility electric grid;
passing the power from the at least two transformer units through a plurality of switchgears to a plurality of electric motors using at least one open air relay cable; and
with each of the plurality of electric motors, driving one or more hydraulic fracturing pump.
