One very important thing you are forgetting is the VFD (Variable Frequency Drive) that is where most of the cost is eaten up in a System 2.0. Electric motors function very differently than gas motors, but a comparison would be if you car did not have a gas pedal or transmission. Once you started your car it would immediately go to full speed as quick as possible, not brakes, no reverse, no neutral, no variable speed, just off and full speed. That is what the VFD does, it regulates the electricity going to the motor, that is what allows it to have variable speeds on the controller, programmed turn around points, limited top speed, forward and reverse, the ability to have software integrated to the System 2.0, etc.
Without it you have a really high powered electric winch that goes one direction only. When you look at what a VFD that integrates with an electric motor costs, plus having towers and anchors engineered to withstand all the forces being generated you really aren't going to save much or anything at all.
