Minneapolis is preparing to review its data-centre rules while a local moratorium covers larger facilities, putting AI infrastructure’s appetite for electricity and water directly into a city planning debate. The useful detail is unusually concrete: one local data centre’s monthly water use rose from about 334,000 gallons to roughly 3 million in early 2025.
Watch Desk analysis
What happened
The Catholic Spirit reports that Minneapolis officials are considering a new definition of data centres, a project review process, size and location limits, and requirements to report energy and water use. The city’s moratorium on establishing or expanding facilities larger than 350,000 square feet runs from 21 March to 21 November, although some applications can still be submitted during the pause.
The city’s Legislative Research and Oversight report says data centres range from small enterprise sites to hyperscale and artificial-intelligence-oriented facilities with major electrical, cooling and support needs. City officials are seeking public input before a Planning Commission meeting and public hearing scheduled for 13 October.
Why it matters
This is not simply a culture-war argument about whether AI is exciting or alarming. It is a planning question about who pays for the servers, grid upgrades and water systems that make digital services possible. The proposed rules could require developers to reveal resource needs before projects are approved, giving residents something more useful than a glossy promise about jobs.
The evidence also argues against treating “data centre” as a single environmental category. A facility’s cooling system, location and operating pattern can change its demands considerably. A rule that measures only floor space may miss the real burden, which is hiding in the pipes and substations. Glamour has never been much of a coolant.
Our read
Minneapolis is right to move the debate from broad enthusiasm or broad suspicion towards measurable obligations. Developers should have to disclose expected electricity and water use, explain cooling choices and identify who funds related infrastructure. The harder question is whether the city can write rules precise enough to remain useful as the technology changes.
The Catholic Spirit’s account makes the strongest case for treating this as both an AI story and a local-government story: the city is considering rules for facilities that may support AI, while residents and officials must deal with their physical costs whether or not they use the systems themselves.
What to watch
- Whether Minneapolis adopts mandatory energy and water reporting for data-centre applications.
- How the proposed definition distinguishes ordinary facilities from AI-oriented hyperscale sites.
- What developers and utilities say about infrastructure costs and reliability.
- Whether the 13 October public hearing produces changes to the city’s zoning approach.
Discussion spark: Should cities approve AI-oriented data centres only when developers pay the full cost of added electricity, water and infrastructure, even if stricter rules push investment elsewhere?
