Local leaders seek to regulate data center development
Local leaders in Tennessee, including Knox and Davidson Counties, are actively working to create regulations for data center development. A specific proposal in Nashville aims to categorize data centers by size and impose zoning restrictions, as well as require closed-loop cooling systems to mitigate environmental and water impacts. This proactive approach seeks to balance economic growth with community concerns.
Local governments across Tennessee, including Knox County, are moving to establish regulations concerning data center development. Reporter Erin Cantrell highlighted these proactive efforts, particularly in Middle Tennessee. District 20 Councilmember Rollin Horton of Nashville expressed concerns about the lack of existing regulations in Davidson County and is advocating for new legislation.
Horton's proposal in Nashville would classify data centers into small, medium, and large categories, with corresponding restrictions on their proximity to neighborhoods, schools, daycares, parks, and the zoo based on zoning districts. It specifically targets "hyperscale" data centers over 500,000 square feet, proposing a ban on these large facilities within Nashville if the legislation passes. The bill also mandates the use of closed-loop cooling systems to prevent continuous water draw and the discharge of polluted water.
While acknowledging the economic benefits and the necessity of data centers for modern technology like web applications and AI, MTSU economics professor Dan J. Smith noted the "not in my backyard" sentiment prevalent in communities. Smith emphasized the challenge for city leaders to reconcile economic growth with local concerns, a balance Horton's proposal aims to strike by providing community information and input opportunities.
Currently, Tennessee hosts 61 data centers, with most concentrated in the Nashville area, around 10 near Knoxville, and a few in Chattanooga. Other states like South Carolina, Georgia, and Virginia have also introduced similar legislation to limit or ban data centers, though none have yet been enacted into law according to the National Conference of State Legislatures.
