Seattle Enacts One-Year Moratorium on Large AI Data Centers
6/10/2026, 9:08:55 AM
One-Year Moratorium Approved
The Seattle City Council voted unanimously on June 9, 2026 to freeze siting of new data centers over 20 MW for one year, with a possible six-month extension and a mandatory public hearing within 60 days.
Background and Scale
Four unnamed firms have applied to build five data centers that would draw 369 MW—about one-third of Seattle’s average electricity use and enough for roughly 300,000 homes. The city’s grid capacity is about one gigawatt; the proposals would raise demand tenfold relative to the existing 30 data centers.
Key Stakeholders
Mayor Katie B. Wilson, Councilmembers Eddie Lin, Joy Hollingsworth, Debora Juarez, Seattle City Light’s Andy Strong, the activist groups Amazon Employees for Climate Justice and 350 Seattle, and dozens of Amazon and Microsoft employees who sent a large email campaign.
Data & Statistics
- Five proposals, 369 MW total demand.
- Moratorium threshold: >20 MW.
- Existing 30 data centers consume ~10 % of projected demand.
- Email support reported as 10,000–nearly 100,000.
- AI-related spending: Amazon $200 bn, Microsoft $190 bn; total AI investment $390 bn.
- Amazon layoffs: 30,000 in eight months; other sources cite “thousands” of local cuts.
Official Statements
Mayor Wilson said the pause lets the city decide if data centers are a good use of urban land and consider transit or housing contributions. Councilmember Lin warned that large AI facilities drive up utility costs and create air, water and noise pollution.
Criticism & Opposition
Amazon Employees for Climate Justice and 350 Seattle argue AI data centers threaten jobs, raise electricity bills and worsen housing affordability. Liesl Wigand warned against “letting Big Tech burn Seattle to win the AI race.” Critics also flagged a loophole allowing projects filed before the vote to proceed.
Conflicting Reports & Gaps
The Guardian cites “nearly 100,000” supportive emails; Gizmodo reports “10,000.” Layoff figures differ: one source mentions “thousands” of local cuts, another specifies 30,000 Amazon layoffs. The four companies behind the proposals remain unnamed, limiting public scrutiny.
Verbatim Quotes
- “Large AI data centers are popping up across the country, driving up utility costs for residents and small businesses while creating air, water, and noise pollution,” — Councilmember Eddie Lin
- “Today’s passage of the data center moratorium is about doing our homework before making long-term decisions that could impact Seattle’s infrastructure, utility rates, water usage, and sustainability goals,” — Council President Joy Hollingsworth
- “The biggest issue is a belief that AI should be how we solve everything, while ignoring the resources that it costs.” — Liesl Wigand, Amazon senior software engineer, Amazon Employees for Climate Justice
What’s Next
Mayor Wilson said the administration will pursue statewide data-center regulation in the next Washington legislative session, while the city prepares a 60-day public hearing and may extend the moratorium by six months. Activists plan similar campaigns in Spokane and Walla Walla.
