Well, infrastructure is built by the government in an environment where its use is regulated, and for essential things.

Electricity for data centers isn't essential. They should build their own parallel grids, a bit like Google and Facebook and such build their own infrastructure.

I'm not saying they shouldn't develop, but correct management from the governments here would be making them pay for their toys in full. That will also be optimal - they know best which infrastructure and how much they need. No loading the common grid with non-essential things that hurt lights, heating and basic connectivity.

EDIT: Perhaps even a centralized, but separate second grid, for that.
