Businesses: other; energy infrastructure and thermal management evaluation requirements for certain data centers; provide for.

Michigan House Bill 6251 requires developers and operators of large-scale data centers to submit a detailed energy infrastructure and thermal management evaluation to the state public service commission before beginning construction, expansion, or major modifications. A facility is considered large-scale if it has an aggregate critical information technology load of at least 25 megawatts or a total electrical demand of at least 50 megawatts, including phased developments that collectively meet these thresholds. The evaluation must be prepared by a qualified professional and include specific data on anticipated power usage, cooling systems, water consumption, and potential impacts on local infrastructure, with copies required to be filed with affected local governments and electric providers. Developers must pay a review fee and face civil fines of up to $10,000 per day for violations, while the commission is granted authority to issue certificates of completeness that expire after 24 months unless updated or extended.
