It’s a hard to answer because each grid will treat it differently. My own experience when trying to track some of this data down, DCs are largely having to do the same and that’s why a lot of the buildout includes behind the meter generation to make up for it.

There is not a good picture in aggregate though so it creates all kinds of narratives.

Depending on what an "AI datacenter" means, their loads don't fluctuate nearly as much as something like a smelter.

A lot of the problem right now is simply that new massive data centers are crying about being forced to.... pay their fair way.

They are mad that they aren't getting special treatment. They want to be treated better than the aluminum smelting plant.
