Seattle Poised to Ban New Datacenters Amidst Growing AI Infrastructure Concerns

Seattle's city government is poised to implement a year-long moratorium on new datacenter construction, marking a significant move by a major U.S. city amidst a growing national backlash against these energy-intensive facilities. The proposed ban comes as four companies sought approval to build five large datacenters that would have collectively consumed approximately one-third of Seattle's current daily electricity demand.

City council committees unanimously advanced the moratorium and a related resolution on Wednesday. A final vote by the full council is anticipated on Tuesday, which activists view as a procedural step following extensive engagement with city officials. Lawmakers have framed these measures as crucial for protecting residents from escalating utility costs and environmental hazards, while also planning to use the moratorium period to draft specific regulations for the AI industry's substantial infrastructure needs.

The rapid response to the datacenter proposals signals a notable rebuke in a region that serves as a major technology hub, hosting headquarters for giants like Microsoft and Amazon. These companies, despite recent layoffs, are projecting massive investments in AI. The proposed datacenters have also mobilized local tech workers, who have actively organized in opposition. Lawmakers and advocates hope Seattle's tech-centric identity will inspire other jurisdictions to follow suit in regulating datacenters.

Seattle Mayor Katie Wilson expressed alarm upon learning of the proposals in April, stating, "That was the first that I, as the mayor, had heard about this." She and many council members supported the moratorium, noting strong public backing. Climate and progressive activists, along with an Amazon employee group, spearheaded an email campaign and direct outreach to lawmakers. Councilmember Eddie Lin's office reported receiving over 10,000 emails in favor of the moratorium. During the pause, officials intend to establish pollution standards, energy connection requirements, labor standards, and potentially separate utility rates for new "large load" customers like datacenters.

That was the first that I, as the mayor, had heard about this. Both I and many of the councilmembers were happy to move toward a moratorium, especially knowing that there was really strong public support out there for that course of action.
