No, the deal is to buy from Constellation directly. This is not coming from the “grid”. By agreeing to purchase this power directly Constellation can get backing to increase their generation capacity. Without this, Constellation would have to beg Illinois to allow them to push more capacity onto the grid - which impacts other producers, etc. Then they’d have to pay off Pritzker and whoever the current goon is in Chicago - I can’t keep track.
The coming era of SMRs, Small Modular Reactors, will soon be here with Microsoft buying some for it’s Data Centers. It’s only logical that businesses like Amazon, Walmart, Costco and many others that consume gigawatts of power will be needing them and building them all over the place. And any excess power they generate can be put on the grid................
