Selecting conductor for transmission line

How to calculate for transmission line conductor for a particular megawatt power?
Suppose 1000 MW power is transmitted through a particular conductor, first calculate the current for that megawatt power taking a voltage level as constant for this case we have taken 400 KV. The current comes to (1000x103)/0.732x400x1)=4018.00 amps, taking on account for double circuit (4018/2)=2009 amps; which is comparable to twin moose conductor which has 2056 amps current carrying capacity at 50oC.
