Seattle Data Center Freeze Impact

Seattle officials are moving toward a one-year freeze on new large-scale data centers as City Hall weighs the cost of AI-era infrastructure on power, water and neighborhoods. Councilmembers Debora Juarez, Eddie Lin and Council President Joy Hollingsworth announced the proposed 365-day moratorium on April 30, pairing it with a resolution that calls for studies of utility rates, water use, land use, jobs and public health. On May 20, the City Council’s Land Use and Sustainability Committee and the Parks and City Light Committee took up the ordinance and the companion resolution in separate meetings. Residents who testified said they were worried about rising utility bills, water demand, pollution and noise, according to local coverage and city meeting agendas. ### Which Seattle leaders are pushing the freeze? Councilmembers Eddie Lin and Debora Juarez and Council President Joy Hollingsworth announced the plan for an emergency moratorium on April 30, according to the Seattle City Council. The proposal would halt the siting of new data centers for 365 days while the city studies their effects on infrastructure, utility rates, water usage, land use and public health. (council.seattle.gov) Mayor Katie Wilson said on April 18 that her office was working with Seattle City Light, the City Council and other stakeholders on “long-term policy approaches,” including a moratorium on new sites. On May 1, Wilson’s office said city departments had been directed to develop a coordinated response focused on utility costs, community health, pollution, equity and economic resilience.

Seattle officials said four companies had approached Seattle City Light with proposals for five large-scale data centers in the city, according to KOMO News’ account of the May 20 committee discussion. GeekWire reported that two of the five proposals had since been withdrawn after the issue gained attention in April. (wilson.seattle.gov) The five projects would have had a combined maximum demand of 369 megawatts, according to city officials cited by GeekWire and KOMO. KOMO said that amount was enough to power about 300,000 homes, while GeekWire reported it equaled roughly one-third of Seattle’s average daily energy use. Seattle already has about 30 smaller data centers, according to both outlets. (komonews.com) ### Why are residents and environmental groups backing limits? Dozens of residents spoke in favor of the moratorium at the May 20 hearings, KOMO reported. Public commenters cited utility rates, pressure on the power grid, climate concerns, pollution, noise and the effect of large facilities on nearby communities. KOMO quoted Rebecca Wood saying public utilities should prioritize “public needs” over “the profit interests of big tech.” (geekwire.com) Food & Water Watch said on May 19 that 26 Seattle- and Washington-based environmental, labor and public health groups had sent a letter urging the City Council to pass the moratorium quickly. The group said the coalition wanted the city to pause new projects while it adopted safeguards. ### What is the city trying to do about utility bills and water use? (komonews.com) Mayor Wilson’s office said on May 1 that Seattle City Light was finalizing a large-load policy for data centers so that infrastructure, purchasing and other costs would not be borne by Seattle residents or other utility customers. The mayor’s office also said Seattle City Light and Seattle Public Utilities were reviewing national practices and would propose rate structures and legislation “in the next several months” to prevent increased utility costs for residents and businesses. (foodandwaterwatch.org) GeekWire reported that the city’s resolution directs Seattle City Light and Seattle Public Utilities to examine electricity and water use and recommend policies and rate structures that shield customers from cost increases. The same report said the utility deadlines are July 1 and Oct. 30, while zoning and development work at the Seattle Department of Construction and Inspections extends into 2027. (wilson.seattle.gov) ### What happens next at City Hall? Seattle’s May 20 committee agendas show the moratorium ordinance, Council Bill 121214, was before the Land Use and Sustainability Committee, while Resolution 32204 was before the Parks and City Light Committee. KOMO reported that neither committee voted on the measures on May 20. The next milestones are written into the city’s own work plan. (geekwire.com) Mayor Wilson’s office said Seattle City Light and Seattle Public Utilities will bring proposed rate structures and legislation in the coming months, and the city will push for state legislation on data center standards in the 2027 legislative session.
