A court fight over a proposed hyperscale data center in Kentucky has become a test of state law.
At stake is who gets to ask a judge to review major zoning decisions, according to the Kentucky Lantern.
What happens in Simpson County may matter well beyond the proposed 200-acre facility, as residents worry about how large industrial projects may affect their homes, health, and communities.
Here's what to know
In March, the Franklin Planning and Zoning Commission approved a preliminary development plan for a TenKey LandCo data center campus in Franklin, Kentucky, including on-site natural gas-fired power generation.
In April, Franklin Citizens for Responsible Development sued, arguing that the approval was improper.
At issue is House Bill 321, which was signed into law in 2025 and narrows the scope of who can sue over local zoning decisions. According to the Kentucky Lantern, it was intended to increase housing development.

Before the law changed, people who were "injured or aggrieved" could seek review in circuit court. Under the revised version, only people who own property in the same zoning category as the proposed development can do so.
In a May filing highlighted by the Lantern, attorneys for TenKey argued that the citizens group "does not comply with the strict requirements" of the revised law and that the case should be dismissed.
Attorneys for the citizens group pushed back, asserting that the restriction was unconstitutional and unfairly prevents residents from challenging decisions that directly affect them.
More background
The eventual resolution of zoning disputes often determines what gets built near neighborhoods, farms, schools, and parks — and what legal recourse residents have when they object. Such concerns may be especially acute when the development in question is massive data centers.
Developers claim that facilities supporting artificial intelligence and cloud computing can create jobs and generate tax revenue, but data centers also require massive amounts of electricity, water, and land. Those demands often strain local grids, increase pollution if fossil fuels are a part of power generation, and contribute to higher energy costs for households.
At the same time, AI is not solely a strain on energy systems. It can help utilities forecast demand, cut waste, improve building efficiency, and integrate more wind and solar power.
Still, the technology's rapid expansion has raised concerns about security, misuse, and whether communities will be left to shoulder the costs and drawbacks of infrastructure they had little meaningful chance to challenge or shape.
On August 24, the Kentucky Lantern reported, Judge Mark Thurmond of Simpson County Circuit Court said he had a "pretty good idea" of his thinking on the case, though he wanted to "look more carefully at" some of the issues before another hearing in October.
What's being done?
For now, the main fight is playing out in court.
The citizens group is asking the judge to allow the case to proceed and to reject the idea that only landowners in the same zoning category can challenge a development.
In a June filing highlighted by the Lantern, lawyers for the Franklin Planning and Zoning Commission pushed back, calling it a "huge and unjustified 'ask'" to declare the law unconstitutional.
Community advocates say the outcome could shape how residents respond to controversial projects in the future, not just data centers.
If the law remains in place, people living next to industrial or commercial development could find themselves shut out of court review based solely on how their property is classified on a zoning map.
Where can I learn more?
The dispute in Simpson County is part of a wider rush to build AI infrastructure, often with little opportunity afforded for nearby communities to weigh in.
The stories below look at how developers line up land, power, and subsidies — and how residents can end up paying the price through environmental impacts, increased fossil fuel generation, and higher utility bills.
• Across rural counties, AI developers are using unincorporated land to bypass city rules.
• In Ohio, utilities are approving gas plants before locals can meaningfully weigh data center impacts.
• In Maryland, households could pay extra to subsidize energy-hungry data center growth.
• For homeowners, data centers are creating power quality problems that can disrupt appliances and electronics.
They also help underscore why the Kentucky case could have broader implications. The legal and political decisions that shape where data centers are sited and how they operate can determine who bears the risks and whose objections are taken into account.
