1. A system for fracturing a well, the system comprising:
a hydraulic fracturing unit comprising:
a chassis,
a pump connected to the chassis and configured to pump a fracturing fluid,
a powertrain connected to the chassis and configured to power the pump, and
auxiliary equipment driven by a motor to support operation of the hydraulic fracturing unit including the pump and the powertrain;

an electric power arrangement configured to power the auxiliary equipment, the electric power arrangement comprising an engine-generator set configured to generate electric power;
an electric power network configured to deliver electric power generated by the engine-generator set to the motor, the electric power network connected to the engine-generator set and the motor, the electric power network configured to connect to one or more of a utility power grid, a battery bank, or another engine-generator set responsive to a failure or fault of the engine-generator set of the electric power arrangement, and the electric power network comprising an electric bus positioned to connect the hydraulic fracturing unit to the electric power arrangement; and
a manifold connected to the pump, the manifold configured to deliver fracturing fluid from the pump to the well.
