SF pauses new data centers in heart of AI
▼ Summary
– San Francisco’s board of supervisors unanimously passed a 45-day moratorium on new data centers, which can be extended to 22 months.
– The pause halts specific projects in Bayview and Dogpatch while officials study energy, water, air quality, and community impacts.
– Europe faces similar infrastructure challenges, with countries like Ireland and Denmark struggling with grid capacity constraints for data center expansion.
– European data centers consume significant portions of national electricity, leading to halted connections and long waiting periods for new sites.
– While San Francisco pauses growth to assess local effects, Europe struggles to build the capacity required by the Commission despite substantial private investment needs.
San Francisco has halted the construction of new data centers, a move that underscores the growing tension between rapid artificial intelligence expansion and local infrastructure limits. The city’s Board of Supervisors voted unanimously on Tuesday to implement a 45-day moratorium on all new data center projects, with the authority to extend this pause for up to 22 months if necessary. This decision immediately blocks a proposed expansion in the Bayview neighborhood and a separate 49.5 MW facility planned for Dogpatch, both of which were in various stages of development or permitting.
The measure was authored by Supervisor Shamann Walton of District 10 and co-sponsored by Connie Chan, Jackie Fielder, and Cheyenne Chen. According to Mission Local, the legislation directs planning officials to conduct a comprehensive study examining the potential effects on energy consumption, water usage, air quality, land use, and community impact. The board is scheduled to review the findings from this study at a hearing due in November.
Walton emphasized the necessity of understanding the full scope of these developments before allowing them to proceed. “We need to know what these impacts are,” Walton said. “Until we know what that is, it needs to stop.”
The immediate effect of the moratorium is to freeze two specific high-profile projects. NOVVA, which had applied to increase its power draw at a site on 400 Paul Avenue in Bayview from 9 MW to 36 MW, must now halt its expansion plans. Additionally, a waterfront building in Dogpatch, designed to consume 49.5 MW, was in active permit discussions with Mayor Daniel Lurie’s policy staff as of August, according to the San Francisco Standard. Sponsors of the Bayview-Hunters Point project have previously argued that the area is already overburdened by existing air pollution, making the addition of large-scale industrial energy users particularly contentious.
Determining the total scale of the industry within the city remains difficult. Bloomberg reported that there is no comprehensive tally of active or approved facilities, while the San Francisco Standard identifies only six known sites. This lack of transparency complicates efforts to assess the cumulative strain on municipal resources.
San Francisco’s cautious approach mirrors challenges currently facing Europe, although the underlying causes differ significantly. In South Dublin, the County Council rejected Google’s application for a third data center at Grange Castle in 2024, citing insufficient grid capacity rather than environmental concerns. The Irish experience highlights the severity of the power demand crisis; the Central Statistics Office found that data centers consumed 23% of the country’s metered electricity in 2025, a sharp rise from just 5% in 2015. This single sector now uses more power than all urban households combined.
Denmark has taken even stricter measures. Its national grid operator, Energinet, halted all new connection agreements earlier this year after facing a backlog of approximately 60 GW against a national peak demand of only 7 GW. Consequently, the European constraint has inverted from a desire to build to an inability to connect. Nscale’s £2 billion site in Essex, backed by Microsoft as an anchor tenant, failed to secure the required 90 MW in time for its 2027 opening. In Britain, some grid connection waits now stretch close to a decade.
While Europe struggles to bring new capacity online, San Francisco is pausing growth entirely. The European Commission aims to triple data center capacity across the continent within seven years, a goal requiring roughly EUR 200 billion in private investment. Meanwhile, San Francisco’s six identified sites face an indefinite review process, with no clear list of operators or total projected load available to the public.
