# Wisconsin Regulators Assign Data Center Power Costs

The Public Service Commission of Wisconsin approved a roughly 7% We Energies rate increase phased across 2027 and 2028, extended recovery of about **$1 billion** in retired power-plant costs, and set the utility’s return on equity at 9.5%. The commission directed that construction costs for power plants tied to new data centers be assigned to those large customers rather than spread across household ratepayers. Transmission cost allocation and a pending We Energies–Oracle agreement for the Project Lighthouse data center campus remain unresolved.

- Companies planning data-center projects in Wisconsin should account for power-plant construction costs being assigned to large customers when evaluating project economics and electricity requirements.
- The pending We Energies–Oracle agreement and FERC’s review of American Transmission Company’s transmission-cost proposal could affect project power costs and transmission arrangements.
- Energy developers and contractors can use the 2027–2028 rate increase schedule and the next state rate case as planning context; the allocation of transmission costs remains unsettled.
