Public utilities: other; contracts to service data centers; require to be treated as a contested case. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 6bb.

This bill requires the Michigan Public Service Commission to review special contracts for large data centers as formal legal disputes rather than simple administrative approvals. It directly affects electric and gas utilities that sign agreements offering unique rates or terms to data centers expected to use 100 megawatts or more of power. Under the new rules, these contracts cannot take effect until a full hearing is completed and the commission issues a final decision, ensuring the process is transparent and not decided behind closed doors. The legislation clarifies how to count power usage across connected facilities and defines specific terms like "large-load data center" to apply these requirements consistently.
