Seattle just drew a line. On June 9, the City Council voted 9-0 to put a one-year pause on building massive new data centers in the city — and it wasn't close.
Here's exactly what the vote does. It's a one-year emergency moratorium on NEW large-scale data centers, the giant ones that draw more than 20 MVA (roughly 20 megawatts — enough power for thousands of homes). It is not a blanket ban. Smaller facilities aren't affected, and projects already approved can move forward. The council can extend the pause another six months if it needs more time.
So why hit pause? Because these facilities are enormous, and the questions are real. A companion bill orders the city to study how big data centers would strain Seattle City Light's grid, how much water their cooling systems would swallow during a statewide drought emergency, what they'd do to residential utility rates, and how industrial-scale construction would land on South Seattle neighborhoods that have already carried more than their share of pollution.
The public response was overwhelming. Councilmembers said they received more than 98,000 emails. At the hearing, 52 people stood up to speak in favor — and not a single person spoke to defend the data centers. One councilmember summed it up: "We're not a company town."
This is what it looks like when a city tells the AI build-out: prove it won't break our grid, drain our water, or spike our bills before you pour the concrete. A year to look before leaping. Reasonable — or an overreach that pushes jobs and investment elsewhere?
