What is the cost to transfer a KWH by high voltage DC transmission lines?
Clearly at each end of the line there is a fixed up and down voltage translation cost. The transformation ratio will have some impact on this fixed cost, as will the power level.
A big factor is the length of the transmission line.
What is an optimum voltage level?
Is it feasible to consider a 2000 mile line?
At 2000 miles, or some other long distance is $0.01 / KWH feasible?
Obviously the cost needs to include the lost energy in the transmission system as well as the cost of the system.
An associated question is --- what is the cost per KWH for pumped storage where the capacity is for 1 day of energy, and 7 days of energy? Energy being the total demand of the system.
