Wisconsin's utility regulator approved a new rate structure Friday requiring data centers to cover 100% of their energy costs instead of shifting expenses to residential customers. The decision strengthens consumer protections by eliminating a proposed subsidy mechanism, lowering the threshold for which data centers qualify, and extending contract terms to 15 years — changes that prevent cost-shifting as massive AI data centers move to Port Washington and Mount Pleasant. The PSC made these changes after 13 months of review because the new facilities could eventually demand as much power as all existing We Energies customers combined, making cost allocation the key decision point for protecting ratepayer bills.
