I have never had to even think about the steps a firm with massive utility requirements would need to take to secure supply. So assuming you could wave a magic wand and instantly build out a datacenter in northern Virginia right now, the local power utility (Dominion Energy in this case) would not be able to provide power?
It isn't like you can snap your fingers and magically transport 10MW+ of power to your doorstep. Plus, as I said in other threads, it isn't just power... it is everything around supporting that power. Try ordering a transformer. Or getting EPA approval to install backup generators.
