Kentucky PSC Opens Investigation into High Electricity Costs, Affordability Concerns

The Kentucky Public Service Commission initiated a formal proceeding to examine causes and potential solutions related to increasing electricity rates in the state. The action follows advocacy efforts by environmental organizations, including the Sierra Club, which submitted materials to the commission urging such an investigation.

Data presented in the PSC’s announcement indicated that residential electricity prices rose substantially over a five-year period, climbing from 10.87 cents per kilowatt-hour in 2020 to 13.24 cents per kWh in 2025. Officials acknowledged that the increases have disproportionately affected lower and moderate-income households throughout Kentucky.

The Sierra Club and allied groups have identified the state’s reliance on coal-fired generation as a primary factor in elevated costs. Environmental advocates also raised concerns about potential future impacts from large-scale data center development, noting that such facilities require significant electricity consumption. According to research cited in advocacy materials, transitioning away from coal and natural gas while expanding energy efficiency, renewable generation, and battery storage infrastructure could generate substantial savings for utility customers.

Mark Ritter, legislative chair for Sierra Club Kentucky, characterized the PSC’s decision as an important initial step toward fulfilling the commission’s stated mission to ensure “safe and reliable service at a reasonable price.” He emphasized that customers across the state face affordability challenges stemming largely from aging coal plant operations and called for the commission to address both coal dependency and data center expansion impacts as the proceeding advances. Environmental advocates signaled their intention to participate actively in the investigation to promote affordable electricity, improved air quality, and service reliability.
