1. Whatever it is...
... they'll want to go with the 500 kv setup so they can build new coal plants at the end of it later.

I'm guessing a 500 kv line of equal capacity to a 115 kv line uses less raw materials overall, but the mandated clearances around the higher voltage lines are greater.

If we lived in a civilized nation, we might use more underground HVDC transmission lines:
