Wisconsin Regulators Approve Data Center Rate to Shield Other Customers

The ruling sets a template for how Wisconsin will bill hyperscale data centers.

Overview

  • The Public Service Commission unanimously approved a special We Energies tariff Friday after a 13‑month review and more than 2,000 public comments.
  • Commissioners added safeguards on transmission charges where state law allows, noting that federal regulators control most transmission pricing.
  • The plan now requires 15‑year agreements and covers facilities of 100 megawatts or more to pull very large sites into the rule.
  • Commissioners also removed a capacity‑only option that would have left about 25% of some plant costs for other customers.
  • Utility filings say new campuses in Mount Pleasant and Port Washington could double We Energies’ load by 2030 and drive about $19.3 billion in new generation spending.
