Some of these are pipe dreams. A Microsoft datacenter at 2.5MW, another at 2MW. There's no way they're going to get generation capacity for that load.

Why is that a pipe dream? It’s BTM for at least one of the sites you are talking about. The only constraint, which is real, is availability of turbines but other than a delayed timeline i am not sure what’s a pipe dream.

2.5 MW / 2 MW are tiny. I think you are confused.

The office building I’m sitting in has a 2 MVA transformer feeding a 2500A 480V three-phase service, 2 MW is peanuts.

are you off by a K? from the article - 'As of early August, ERCOT was considering more than 474 gigawatts of requests to connect to the Texas electric grid, about 90% of which came from data center projects.'
