Knoxville is hitting pause on the kind of massive data centers that guzzle power and water, at least for the next year. City Council voted unanimously last week to approve an emergency one-year moratorium that freezes permitting and construction of large data centers inside city limits, giving planners time to figure out where these facilities belong and how they should be regulated.
The ordinance, listed on the council's July 7 agenda as an emergency measure, targets large data centers that would require ten (10) megawatts or more of power. It directs Knoxville-Knox County Planning and city staff to develop zoning code changes and safeguards, according to the City Council agenda. Council approved the item on first reading and instructed staff to come back with proposed definitions and guardrails.
Mayor Indya Kincannon framed the move as a preemptive step to avoid the kind of messy fallout other communities are dealing with. "We want to protect our clean air, our clean water, and make sure that we are not saying yes to things that harm our community," she told reporters. As WVLT reported, Kincannon also drew a line between modest, low-power operations and hyperscale data centers that demand vast amounts of electricity and water.
Regional Pause Builds Momentum
Knoxville is not acting in a vacuum. Across the region, neighboring cities and counties are scrambling to get ahead of the data center wave, drafting rules, setback limits and noise standards aimed at keeping industrial-scale buildings from crowding out neighborhoods and scenic views.
Hoodline coverage has tracked how counties from Knox to Loudon and Anderson are already studying and regulating big data projects. One recent story, Knox County Tells Data Centers, lays out draft zoning ideas local planners are mulling, including efforts to curb noise, improve aesthetics and push operators to secure their own water supplies.
Why Planners Want A Pause
Local officials say their concerns fall into three buckets: strain on the electric grid, heavy water consumption and constant industrial noise. Existing city codes were not exactly written with football-field-sized server farms in mind.
A Knox County commission resolution reviewed by city officials notes that a very large facility can use on the order of 200,000 to 300,000 gallons of water per day for cooling, depending on its size and design, according to Knox County's resolution. The City of Knoxville also emphasizes that staff will now draft specific limits and notes that no hyperscale data center proposals are currently on file with the city.
What's Next For Knoxville
Over the coming months, planning staff will work up recommended code changes, hold public meetings and coordinate with utilities to map out where large computing loads might fit without disrupting nearby homes or businesses.
Local outlets report that the pause is expected to last about a year, through roughly July 7, 2027, unless the city adopts updated zoning rules sooner. Spectrum Local News notes that the moratorium is also meant to keep city and county planning in sync so utilities are not blindsided by sudden, massive power demands.
Policy Backdrop
All of this local maneuvering is happening under a new state law that changes who pays to beef up the grid for big data centers. Under HB 1847 / SB 2128, recorded on the Tennessee General Assembly bill page, developers of large data centers are now responsible for the cost of necessary electric infrastructure upgrades, not local governments or other ratepayers. The Tennessee General Assembly details the bill's status and key provisions, a shift that is likely to influence how Knoxville and Knox County structure their rules and any incentives going forward.
