What Hyperscale Data Centers Mean for Minnesota’s Grid, Water, and Land
The article examines how hyperscale data centers in Minnesota, including Meta's Rosemount campus, could increase pressure on the state's electricity grid, groundwater supplies and land-use planning. It notes that Minnesota has adopted special tariffs for very large electricity customers, but argues that limited disclosure and resource demands remain significant concerns.
Minnesota is seeing rapid growth in large hyperscale data centers, particularly around communities such as Rosemount and Farmington. The article says individual facilities can require hundreds of megawatts of electricity and consume millions of gallons of water daily for cooling, placing pressure on the grid, groundwater supplies and municipal planning. Meta's Rosemount data center occupies 280 acres and is expected to support about 100 permanent jobs despite its substantial land footprint.
Minnesota lawmakers and the Minnesota Public Utilities Commission have adopted requirements for very large customers to pay for dedicated substations and transmission infrastructure. However, the article argues that confidential utility agreements obscure projected energy demand and infrastructure costs, while new data center load could complicate the state's goal of reaching 100% carbon-free electricity by 2040. It also warns that industrial groundwater withdrawals for cooling could compete with drinking water and agricultural needs.
