MI SB0237

Extends the use tax exemption for data center equipment from December 31, 2050 to December 31, 2050 for standard facilities, and to December 31, 2065 for facilities on brownfield sites or former power plants.

Creates a new "enterprise data center" certificate program administered by the Michigan Strategic Fund, requiring applicants to demonstrate a minimum $250 million capital investment and creation of at least 30 qualified new jobs paying 150% or more of the prosperity region median wage.

Requires enterprise data centers to obtain green building certification (BREEAM, ENERGY STAR, LEED, or similar) within 3 years of operation and procure clean energy equivalent to 90% of forecasted annual electricity usage.

Prohibits enterprise data centers from receiving state or local property tax benefits unless approved by local governing bodies, and restricts access to specific long-term industrial electric rates and tariffs that would subsidize residential customers.

Establishes the Michigan Strategic Fund may not issue new certificates after December 31, 2029, and requires certificate revocation if facilities fail to meet requirements, with penalties requiring repayment of exemptions plus interest.
