Tennessee communities are blocking data centers. Nashville could be next.
Tennessee communities are enacting and proposing temporary bans on new data center construction due to concerns over environmental impacts, electricity use, and noise pollution, despite state incentives. Nashville's Metro Council has proposed a moratorium following public opposition to a DC BLOX project near the Nashville Zoo, while other communities like McMinnville have already enacted bans.
Communities across Tennessee are increasingly implementing temporary moratoriums on new data center construction amidst a statewide boom and growing public backlash. Since last fall, nine cities and counties in Tennessee have enacted construction bans, with five approved recently, and at least three more, including Nashville and Knoxville, are considering proposals. Proponents of these moratoriums argue they are necessary to study local impacts, enhance the power grid, and establish appropriate regulations, directly contrasting state policies that incentivize data centers and fast-track power plant development.
In Nashville, the Metro Council initiated steps to pass a proposed moratorium, introduced by Councilmember Courtney Johnston. This action follows significant public outcry, including a petition signed by over 380,000 people, against a planned DC BLOX data center adjacent to the Nashville Zoo in Grassmere Park. Johnston stated the moratorium is a "responsible pause" to allow Metro to modernize its zoning code and protect residents, public spaces, and the zoo before irreversible decisions are made, particularly as the city's code currently lacks a definition for data centers. The proposed legislation, which passed its first reading, would halt new permit approvals until November or until updated zoning laws are passed, though some permits for the DC BLOX project have already been approved. The Nashville Zoo has filed a zoning appeal against these existing permits, citing potential impacts on endangered wildlife.
Concerns driving these local actions include the substantial electricity and water consumption of data centers, along with increased noise and air pollution. The article highlights a class-action lawsuit filed by Memphis-area residents against Elon Musk's xAI (owned by SpaceX) Colossus facilities over noise pollution. Developers like DC BLOX argue that not all data centers are alike and that their projects often include funding for energy infrastructure, such as new substations. Other Tennessee localities, including McMinnville and Coffee County, recently enacted moratoriums. McMinnville's 18-month ban followed a proposed 25 MW AI data center project by Hixson, which failed to consult local officials before its announcement, prompting Mayor Ryle Chastain to seek time for environmental impact studies.
While many states, including Tennessee, offer tax incentives for data centers and have recently passed legislation allowing large data centers to produce "behind-the-meter" power without state regulator approval, this has raised environmental concerns about unregulated gas plants. The Tennessee Valley Authority (TVA), which supplies power to most of Tennessee, is considering special rates for data center owners to ensure large users pay their fair share. Nationally, recent polls indicate a strong and growing opposition to AI data centers in local areas, with 70% of Americans opposing them, a significant increase from nine months prior.
