Kentucky sues Cave City over Mammoth Cave–adjacent AI data center moratorium ⛏️

The developer behind a proposed $4.8 billion AI data center near Mammoth Cave National Park is suing Cave City, Kentucky, after officials imposed a one-year moratorium on new data centers days after the project was filed. Kentucky Industrial Alliance has filed two lawsuits against the city and is separately challenging the city's 2024 annexation of the 600-acre parcel, arguing the property should sit outside city limits and outside the reach of the moratorium. The planned 1.2-gigawatt AI and cloud computing campus is slated for a site north of downtown.

The dispute has fueled local opposition centered on the project's proximity to Mammoth Cave National Park. "I'm 100% against a data center being the identity of the entrance to Mammoth Cave," Cave City councilwoman Leticia Cline told The Lexington Herald-Leader. Residents and officials have raised concerns about groundwater, sinkholes, power demand and other environmental impacts in the region's karst landscape. The National Parks Conservation Association warned in March that data center development in Virginia has increased more than 500% since 2015, underscoring the need for stronger safeguards around national parks.

Cave City officials say the pause was needed to evaluate projects of this scale. Kentucky Industrial Alliance disputes those concerns, saying the campus would use a closed-loop cooling system, create about 360 direct and indirect jobs, and generate millions of dollars in annual tax revenue. "Every major project deserves thoughtful consideration based on accurate information and respectful discussion," the company said in a statement.

The fight mirrors a broader pushback against AI infrastructure. Lawmakers in Maine, New York, Pennsylvania, Michigan and Virginia have considered or advanced moratoriums or other restrictions on new projects amid concerns over local community and grid impacts. In Emporia, Kansas, high school physics teacher Lux Claridge of Emporia High School was arrested and carried out of a city commission meeting after applauding several times in support of speakers criticizing the proposed 1,000-acre Flint Hills Digital Campus, according to local broadcaster KWCH, which reported that attendees had been warned against clapping and snapping before the meeting.
