The new rate mandates data centers like Microsoft and OpenAI pay all costs for new natural gas plants, with eligibility lowered to 100 megawatts and service agreements extended to 15 years.
The Public Service Commission also ordered utilities to assign transmission costs directly to data centers, aiming to shield residential customers from higher bills amid We Energies’ major expansion plans.
This decision follows public backlash and local restrictions on data center development, with ongoing concerns about affordability and environmental impact as Wisconsin becomes a hub for large-scale AI infrastructure.

How Wisconsin’s $5 Billion Data Center Power Plan Sets a National Precedent for Cost-Sharing
Overview
In April 2026, the Wisconsin Public Service Commission approved a groundbreaking electric rate structure requiring large data centers to fully cover the costs of new power generation and transmission infrastructure. This decision protects residential and small business customers from subsidizing the massive energy demands of data centers, which are driving significant infrastructure investments including new natural gas plants. The ruling extends service agreements to 15 years and mandates transparency in cost tracking, fostering collaboration between utilities and data centers. While the decision sets a national precedent and encourages sustainable energy strategies, it also highlights ongoing environmental challenges linked to fossil fuel reliance, emphasizing the need for vigilant enforcement and balanced growth.
