Kentucky PSC Investigates Rising Electricity Costs Amid Affordability Concerns

The Kentucky Public Service Commission has opened a formal investigation into rising residential electricity costs and energy affordability across the Commonwealth. The state regulatory agency announced the new proceeding to allow utility companies, consumer advocates, and local residents to identify the root causes of increasing power bills and explore potential policy solutions.

The decision follows intensive advocacy by Sierra Club Kentucky and partner organizations, which submitted a joint letter requesting an affordability docket. According to data cited by the regulatory agency, the average residential electricity price in Kentucky surged nearly 22 percent over a five-year period. Rates increased from 10.87 cents per kilowatt-hour in 2020 to 13.24 cents per kilowatt-hour in 2025, placing a growing financial burden on low- and moderate-income households.

Advocacy groups have raised concerns that Kentucky’s heavy reliance on aging coal-fired power plants is driving up monthly utility bills. Environmental organizations are also pointing to the potential rapid expansion of energy-intensive data centers as a major factor that could further strain the state's electrical grid and increase rates for everyday consumers.

A recent study highlighted in the proceedings suggests that shifting away from coal and natural gas generation could significantly lower long-term costs. The research indicates that investing in energy efficiency programs, clean energy generation, and utility-scale battery storage could save Kentucky ratepayers billions of dollars while improving grid reliability.

Mark Ritter, legislative chair for Sierra Club Kentucky, commended the commission's decision to open the affordability inquiry, noting that utility customers across the state are currently struggling with escalating operational and living expenses.

Ritter stated that the commission's self-professed mission is to provide customers safe and reliable service at a reasonable price, making an affordability docket the right first step toward achieving that goal. Right now, utility customers in every corner of the Commonwealth are struggling to afford rising costs to keep their homes powered and businesses open, largely due to our continued reliance on aging and expensive coal plants, Ritter said. As this docket progresses, we will continue to urge the PSC to address concerns surrounding coal reliance and the potential impact of data center deployment on what Kentuckians have to pay just to live and work. Affordable energy, cleaner air, and reliable service is what Kentucky needs to build a sustainable future, and we will keep fighting for it.

The Public Service Commission will collect testimony and data from public utilities, energy experts, and community members throughout the formal docket process. The investigation aims to establish actionable strategies to ensure electricity remains accessible and affordable for all Kentucky residents while maintaining grid stability across the region.
