Step up transformers raise the voltage greatly to reduce current needed and power loss. Taken from Wikipedia on electric power transmission: "a 100 mile 765 kV line carrying 1000 MW of power can have losses of 1.1% to 0.5%. A 345 kV line carrying the same load across the same distance has losses of 4.2%. For a given amount of power, a higher voltage reduces the current and thus the resistive losses in the conductor." (dhg again) MW is million watts kV is thousand volts Power is voltage times current. Raise the voltage and you can send more power using less current. Power loss due to resistance is the square of the current times the conductor resistance. Therefore, halving the current flow by doubling voltage reduces power loss to a quarter. Assuming 1%/hundred miles and 700 miles, you would lose roughly 7% of your input to line resistance. If you assume 4%/100 miles, you would lose about 28%. David trying to be helpful REGARDING

I obviously don't understand how the power grid works. Would that be a direct connection? Or is more of a "I put 178 megawatts into the pot, so I'm taking 178 megawatts out and let's call it even? RTR, thanks! I obviously don’t understand how the power grid works.
