The proposed bill, titled the "Data Center Energy Infrastructure and Thermal Management Evaluation Act," mandates that developers or operators of large-scale data centers submit comprehensive evaluations regarding their energy infrastructure and thermal management before commencing construction or significant modifications. Specifically, these evaluations must detail anticipated electrical demands, cooling systems, and necessary infrastructure, and must be prepared by qualified professionals. The evaluations must be submitted to the Michigan Public Service Commission (PSC) at least 120 days prior to any construction activities, and a certificate of completeness must be obtained from the PSC to proceed. The bill also outlines the process for public notification and the requirement for a public summary of the evaluation, while allowing for certain proprietary information to be kept confidential.

Additionally, the bill establishes civil penalties for non-compliance, with fines of up to $10,000 per day for violations. The PSC is granted the authority to promulgate rules for the implementation of this act, which is designed to ensure that large-scale data centers operate efficiently and with minimal impact on local infrastructure and resources. The act will take effect 90 days after being enacted into law.
