New Legislation for Data Centers in Minnesota Clarifies the Path Forward
Data centers and data center regulation were recurring topics in the Minnesota legislature’s 2025 session. As data centers flock to Minnesota, there was a concerted effort to create a clearer framework for data center developments. In its June special session, the state legislature passed several new requirements for data centers in Minnesota that will shape their construction, finances and regulatory permitting processes. The legislation, judged a bipartisan compromise by the Star Tribune, maintains or extends some tax breaks for data centers while imposing new rules aimed at protecting the environment and helping individual energy consumers. Here is an overview of the key provisions of this legislation: Tax exemptions While lawmakers eliminated the electricity sales tax exemption for data centers, they also extended a sales tax exemption for software and IT equipment for large-scale data centers to 35 years. Previously, the exemption had been set to expire in 2042. Water use and green building standards The legislature established a new category of water appropriation permits for over 100 million gallons per year. Projects using over this amount of water must undergo pre-application evaluations and meet new permitting conditions. Additionally, new green building standards state that data centers must qualify under one of several sustainable design standards. Centralized permitting & regulatory support The new rules require all state agencies to refer data center inquires to the Minnesota Business First Stop program. This change is intended to improve permitting timelines and interagency coordination. Electricity regulations The law added ratepayer protection language to stipulate that large-scale energy users cover their own costs. The goal is to ensure that utilities and/or ratepayers are not subject to increased costs due to the large energy needs of data centers. Legislators also established an optional clean energy tariff to segregate clean energy costs to clean energy users. Additionally, they removed data center power from the calculation used for public utilities’ minimum solar generation requirements. Megawatt usage fees to fund conservation programs Data centers are subject to a new annual fee based on their peak demand megawatt (MW) usage, as outlined in the table below. This fee will be used to fund energy conservation programs for low-income households. MW Usage Fee 100- 250 MW $2,000,000 251- 499 MW $3,000,000 500 – 749 MW $4,000,000 750+ MW $5,000,000 Wage standards for workers The new law defines prevailing wage requirements for construction laborers and mechanics working on data centers. What these changes mean for data centers in Minnesota going forward If you’re planning to build or expand a data center in Minnesota, the new legislation brings some clarity to the process. With these changes, developers can more confidently move ahead with data center projects designed to leverage Minnesota’s advantageous climate, location and workforce. As always, early engagement with legal, engineering and utility partners will be critical to clear the path ahead.
