Why It Matters
Kentucky is facing a potential wave of large-scale data center development that could fundamentally reshape the state’s electricity grid, utility rates, and rural communities. The scale of projected power demand raises serious questions about who will bear the infrastructure costs and whether existing ratepayers will be protected.
What Happened
Louisville Gas and Electric and Kentucky Utilities, the state’s largest electric utility, disclosed to state regulators earlier this year that nearly 30 data center projects are currently in their economic development pipeline. Of those, 11 have at least a 50% probability of moving forward, and four have been designated as “imminent” — meaning there is an 80% or greater likelihood they will be built.
The CEO of LG&E and KU’s parent company told investors in May that the total projected electricity demand from the full slate of potential data centers could reach approximately 12 gigawatts. For comparison, the maximum electricity output recorded across Kentucky utilities during summer 2024 was 18.4 gigawatts — meaning data centers alone could account for roughly two-thirds of the state’s current generation capacity if all projects materialize.
The 11 highest-probability projects carry a combined electricity demand of nearly 3.5 gigawatts — enough to power more than 2 million homes.
One of the planned “imminent” sites is in West Louisville. Other utilities in the state are separately pursuing large data center developments, including proposals at a former aluminum mill site in Western Kentucky and an Eastern Kentucky industrial park.
By the Numbers
- 29 — total data center projects in LG&E and KU’s pipeline
- 11 — projects with at least a 50% probability of proceeding
- 3.5 gigawatts — combined electricity demand from the 11 highest-probability projects
- 12 gigawatts — total projected demand from all potential data center projects
- 18.4 gigawatts — Kentucky utilities’ maximum recorded generation capacity in summer 2024
Community and Regulatory Concerns
Residents near proposed sites have raised a range of objections: potential upward pressure on electricity bills, substantial water consumption required to cool server facilities, noise pollution, declining property values, and the conversion of rural land for industrial use.
Critics also question how rigorously the utility has vetted the likelihood that prospective projects will actually be built. Byron Gary, an attorney with the Kentucky Resources Council, said the utility’s probability assessments appear to rest largely on internal business judgments rather than verifiable external benchmarks. “They just appear to be based on their business judgments, which doesn’t really have any objective grounding,” Gary said.
Gary added that no cost studies have yet been produced demonstrating that revenue generated by data centers would outpace the costs of serving them — leaving open the question of whether existing ratepayers would ultimately benefit or be left holding the bill.
LG&E and KU spokesperson Liz Pratt pushed back on those characterizations, saying the utility’s pipeline methodology is grounded in “established economic development practices” and that projects classified as imminent have already undergone infrastructure and siting evaluations. She acknowledged that not all projects will come to fruition but said overall interest remains substantial.
Legislative and Infrastructure Response
State lawmakers have previously enacted sales tax incentives to attract data centers to Kentucky, but no regulations currently govern the fiscal or environmental costs these facilities impose on the state. A bill this legislative session that would have required data centers to fund their own electricity and water infrastructure failed to pass before the session ended.
LG&E and KU is now moving forward with plans to construct two natural gas power plants, citing projected demand growth partly driven by data centers. The utility is also retaining a coal-fired power plant unit that had been scheduled for retirement in anticipation of future electricity needs.
Zoom Out
Kentucky’s situation reflects a national pattern. The rapid expansion of artificial intelligence services has driven demand for “hyperscale” data centers — facilities consuming electricity at the scale of entire power plants — across multiple states. North Carolina has moved to address similar pressures through proposed tax changes and consumer protections targeting the data center sector. Virginia remains the country’s largest data center market, dwarfing what Kentucky is currently projecting.
What’s Next
The Kentucky Public Service Commission will continue reviewing utility resource plans that factor in data center demand. Whether new legislation addressing data center oversight advances in the next session remains uncertain. Community opposition, as seen in Mason County and other areas, is likely to intensify as specific site proposals move forward.
