Data centers will cost ComEd $3 billion but consumer groups worry Illinois households will be on the hook

Commonwealth Edison projects more than $3 billion in grid upgrades to serve 30 large-load users believed to be data centers across Illinois, but developers have committed only about $721 million so far. Consumer advocates warn that households and small businesses could bear costs if projects are delayed or canceled, while ComEd says regulatory agreements will protect ratepayers.
