Alliant Energy

Alliant Energy has been ordered to refile a data center contract in Wisconsin. Regulators found issues with the original submission requiring a new filing. The utility serves the Wisconsin market and is pursuing arrangements to supply power to data center customers. No specific MW capacity, project value, or general contractor details are disclosed. This regulatory action highlights growing scrutiny of utility-data center agreements in the state. Data center developers and power infrastructure vendors operating in Wisconsin should track this proceeding closely.

The Wisconsin Public Service Commission has required Alliant Energy to file a new application with fewer redactions for its proposed data center rates. The PSC determined that the original filing contained excessive confidential redactions that limited public review. Alliant Energy serves utility customers in Wisconsin and is developing rate structures for large data center loads. No specific capacity or project value details are available. The ruling signals increased regulatory scrutiny of data center utility agreements. Energy consultants, data center developers, and utility contractors should monitor this proceeding for rate structure precedents.
