Longmont considers ban on hyperscale data centers amid growing energy and water concerns
Longmont, Colorado is considering a ban on hyperscale data centers due to significant concerns regarding their energy and water consumption. City Council Member Matthew Popkin proposed the ban, and a proposed ordinance is expected to be presented to the council soon. The city anticipates a final decision by June 9 at the earliest.
The city of Longmont, Colorado is currently considering a ban on hyperscale data centers, which are defined as facilities consuming 100 megawatts or more of electricity at peak capacity. City Council Member Matthew Popkin introduced the proposal in April, citing growing community concerns about the environmental impact of these facilities across the Front Range of Colorado. Concerns extend beyond energy consumption to include increased fire risk, drought, and water usage.
Darrell Hahn, the city’s Electric Utilities Director, highlighted the scale of the proposed ban, explaining that 100 megawatts is roughly half of Longmont's peak electrical load on a hot summer day, equivalent to powering 10,000 to 30,000 homes. Popkin noted that community members have already expressed feedback, urging the city not to approve any hyperscale data center projects.
City staff are preparing a proposed ordinance to present to the council, with a final decision not expected until at least June 9. Hahn confirmed that existing safeguards regarding noise, water use, and power needs would apply to any large-scale development if the ban does not pass, and companies would be responsible for funding necessary infrastructure.
