1. A system for hydraulically fracturing underground formations, comprising:
one or more transportable electric turbine generators;
an electric motor electrically connected to the one or more turbine generators;
one or more fracturing fluid pumps, wherein the one or more fracturing fluid pumps are configured to receive one or more conduit to deliver a fracturing fluid into a wellbore;
an electric blender system, operatively associated with a dedicated electric power source, capable of providing a blended fracturing fluid to a fracturing pump for delivery to a wellbore operation, comprising:
a blender tub;
a fluid additive system;
a fluid addition source hopper;
an inlet electric motor configured to drive an inlet pump, in communication with a fluid additive source and cable of pumping the fluid additive source into and out of the blender tub.
