The Powerline Ekibastuz–Kokshetau in Kazakhstan holds the record for having the highest operating transmission voltage in the world, running at over 1 megavolt. Why did they choose to deliver energy this way?

EDIT:

If higher voltage means thinner wire can be used for transmission, why doesn't the rest of the developed world operate at transmissions this high?
