PJM has lost more than 5.6 net gigawatts in the last decade as power plants shut faster than new ones enter service, according to a PJM presentation filed with regulators this year. PJM added about 5 gigawatts of power-generating capacity in 2024, fewer than smaller grids in California and Texas. Meanwhile, data center demand is surging. By 2030, PJM expects 32 gigawatts of increased demand on its system, with all but two of those gigawatts coming from data centers.
So this is a combination of utter mismanagement by the power companies, combined with growth in data center demand. Data centers are not purely AI. And I would expect that if PJM continues to be a basket case with exceptionally high prices those data centers will move elsewhere, or at least not get set up so more in those locations. Data centers generally don't have to be located in specific places, by their nature. AI-specific ones in particular since the bandwidth required is a lot smaller than their processing power.
Reading will nevertheless help. It's not going to give you perfect form on your breast stroke, but that's not what OP is going for here. He wants to not die if he suddenly finds himself in deep water. There's plenty of benefit from reading about how to go about not dying under those sorts of circumstances.
