I don't think the mechanism is that different, and even if it was Europe, etc would have the same issue - data centers would still bid up the price for existing capacity, and the future capacity added to accommodate the dcs would be added at a higher marginal rate too because scarcity of new supply + base load nature of dc loads. So the problem will get worse before it gets better
Yes datacenters inccrease the prices here but they don't get a cheaper price then everyone else. There is a massive difference there.
