Why It Matters
Kentucky faces a potential wave of hyperscale data center construction that could strain the state’s electric grid and push utility costs onto existing ratepayers. Louisville Gas and Electric and Kentucky Utilities projects 11 facilities with at least a 50 percent probability of locating in the state, carrying a combined power demand of 3.5 gigawatts—enough to supply more than 2 million households.
The electricity requirements arrive as the utility plans billions in new gas-fired generation and keeps a coal unit online past its scheduled retirement date, with ratepayers covering much of the cost. State lawmakers have enacted tax incentives to attract the facilities but have not passed regulations governing infrastructure expenses or environmental impact.
What Happened
LG&E and KU disclosed to the Kentucky Public Service Commission in March that its economic development pipeline includes 29 potential data center projects. The utility identified 11 as having a 50 percent or higher chance of moving forward, with four classified as imminent at 80 percent probability. One of those imminent projects is slated for West Louisville.
In May, the chief executive of LG&E and KU’s parent company told investors the total prospective electricity demand from data centers under consideration could reach 12 gigawatts. Federal records show Kentucky utilities generated a peak of 18.4 gigawatts during summer 2024.
Other electric providers in the state are pursuing similar projects, including proposals to develop two large data centers at a former aluminum mill site in Western Kentucky and an industrial park in the eastern part of the state.
By the Numbers
LG&E and KU’s pipeline includes 29 data center prospects with 11 carrying a better than 50 percent chance of completion. Combined electricity demand from the 11 facilities would total approximately 3.5 gigawatts. The utility’s parent company estimates total prospective demand could reach 12 gigawatts. Kentucky’s statewide generation capacity peaked at 18.4 gigawatts in summer 2024. Four projects are considered imminent with an 80 percent probability.
Community and Regulatory Response
Residents in communities near proposed sites have raised concerns about electricity costs, water consumption for cooling systems, property values, noise pollution, and conversion of rural land. A group called We Are Mason County attended a September planning commission meeting to voice objections to a local data center proposal.
A Republican-sponsored bill that would have required data centers to pay for their own electricity and water infrastructure failed on the final day of the 2025 legislative session. Prior state laws have provided sales tax breaks to attract the facilities but established no regulatory framework for fiscal or environmental costs.
Byron Gary, an attorney with Kentucky Resources Council, questioned the methodology LG&E and KU uses to assess project likelihood, saying the utility’s forecasts appear to rely on internal business judgments without objective verification.
Zoom Out
The surge in data center interest follows national expansion of artificial intelligence services, which require massive computing infrastructure. Traditional data centers supporting cloud storage and online services have operated in Kentucky and other states for years, but AI-driven hyperscale facilities can consume electricity equivalent to entire power plants.
Virginia remains the nation’s dominant data center hub, with Kentucky’s prospective buildout significantly smaller by comparison. The trend has prompted utilities nationwide to forecast steep increases in electricity demand after decades of relatively flat growth.
What’s Next
LG&E and KU is moving forward with plans to construct two gas-fired power plants, citing projected data center demand as part of the justification. The utility is also billing ratepayers for costs associated with delaying retirement of a coal-fired generating unit to meet anticipated load growth.
A spokesperson for LG&E and KU said the utility’s approach reflects established economic development practices but acknowledged not all projects under consideration will materialize. The company did not provide an updated count of active prospects in its pipeline.
Whether state regulators or lawmakers will establish infrastructure cost-sharing requirements or environmental review processes for future data center projects remains uncertain.
