Microsoft challenges $600M data center power plan

Microsoft and Wisconsin ratepayer advocates have challenged a proposed transmission-cost plan for Mount Pleasant data center, arguing it inadequately protects consumers and lacks Microsoft input; the plan would bill data center developers for transmission upgrades and could leave ratepayers bearing significant costs. Microsoft and others seek federal review, with objections filed to FERC and calls for settlement judge procedures, as the utilities plan billions in upgrades and timelines while regulators weigh how to shield customers.
