Seattle City Council unanimously passes a one-year emergency moratorium on large AI data centers; Oct 4 statewide protests call for more
On June 9, 2026 the Seattle City Council unanimously passed Council Bill 121214, an emergency one-year moratorium (extendable by six months) on new data centers above 20 MVA, after four companies sought power for five facilities totalling 369 MW. On Oct 4, 2026 Washington AI Resistance and allied groups held 20+ "Day of Action" events across the state calling for a statewide pause.
Key facts
- Bill: amended Council Bill 121214 (sponsors Eddie Lin and Council President Joy Hollingsworth) plus Resolution 32204 (Debora Juarez) directing studies on grid capacity, water, rates, land use, jobs and health (council.seattle.gov)
- Trigger: four companies approached Seattle City Light about five large data centers with combined maximum demand of 369 MW, about 300,000 homes' worth
- Threshold: facilities with more than 20 MVA of electrical capacity
- Juarez: 'The passing of today's moratorium does not stop AI or data centers. It pauses to hold those accountable.'

What happened
Seattle, home to Amazon and near Microsoft, froze new large data centers while it studies their effects on power, water and rates. Four months later the local backlash had turned into a statewide movement, with Oct 4 protests asking for a pause on the AI data-center boom across Washington.
Why it matters
Local moratoria (Seattle; New York state in July) and organised protest are a growing constraint on AI compute build-out. They are the backdrop to industry pledges like Amazon's "Built Together" fund.
