SO that makes me wonder how big is a 1GW transformer operating at 400kV?
And how much does one cost?
There are plenty of images and descriptions of 400kV transformers
on the web. You have to be an insider to get a fair idea of the
cost. These things are usually made to order. I'd guess a 1GVA
400kV transformer to be between 6 and 7 M$. I'm not an insider
though.

I should add dollars.
Thanks John, but that looks a bit pessimistic.

If I read it right that's 200lb=0.1T for 1kVA so 10^5T for a 1GVA unit.

My current best guess from 4.5T for 1MVA and so 4500T for 1GVA (plus a
bit extra supporting structure to deal with the extra weight).
