Claim 18:
19. A hydraulic fracturing system, comprising:
at least one generator;
a first hydraulic fracturing unit, comprising:
a first support structure having a first length;
two or more first electric-powered pumps arranged on the first support structure, the two or more first electric-powered pumps being quintuplex pumps; and
at least one first electric motor to power the two or more first electric-powered pumps; and

a second hydraulic fracturing unit, comprising:
a second support structure having a second length;
a second electric-powered pump arranged on the second support structure, the second electric-powered pump having seven or more plungers;
at least one second electric motor to power the second electric-powered pump;
a variable frequency drive (VFD) connected to the at least one second electric motor, the VFD configured to control at least a speed of the at least one second electric motor; and
a transformer configured to distribute power for operation of the second electric-powered pump;

wherein a first pumping capacity of the first hydraulic fracturing unit is substantially equal to a second pumping capacity of the second hydraulic fracturing unit, and the power being received at the transformer from the at least one generator to power the second electric-powered power is at a voltage higher than an operating voltage of the second electric-powered pump.
