The Sierra Club released a new scorecard evaluating state electric utilities on their commitment to transitioning away from fossil fuels. Kentucky Power received a D grade, while all other major Kentucky electric utilities received an F.
Why it matters
The rankings highlight the ongoing tension between Kentucky's historical dependence on coal and the broader industry shift toward renewable energy sources. This evaluation reflects a significant gap between the state's energy mix and evolving national generation trends.
Coal currently produces two-thirds of all power in Kentucky, significantly higher than the 16% share coal represents nationwide. The U.S. Energy Information Administration forecasts coal generation will decline by 8% this year and another 6% in 2027.
The players
Sierra Club
This environmental organization advocates for the protection of wild places and the transition to clean, sustainable energy sources.
Kentucky Power
This electric utility serves customers in eastern Kentucky and is the only utility in the state to receive a grade higher than an F.
U.S. Energy Information Administration
This federal agency collects, analyzes, and disseminates independent energy information to promote sound policy-making.
The details
The Sierra Club based its grades on each utility's reliance on coal and natural gas generation compared to their investment in clean energy alternatives. Kentucky Power earned a higher grade than its peers due to specific plans included in its integrated resource plan to construct wind and solar facilities.
Timeline
The Sierra Club released its utility scorecard during the week of September 23, 2026.
Kentucky Power's integrated resource plan was originally developed in 2022.
Nationwide, solar generation surpassed coal generation in May 2026.
Market Landscape
The Sierra Club's scorecard follows the trajectory of coal reduction established by the U.S. Energy Information Administration's Annual Energy Outlook. This evaluation underscores a structural shift as utilities face increasing pressure to replace traditional fossil fuel baseloads with renewable capacity.
The transition away from coal involves significant capital investment that could ultimately impact electricity rates for local residents. Consumers should monitor their utility's long-term resource plans to understand how potential infrastructure shifts might affect their monthly bills.
The takeaway
While Kentucky remains heavily reliant on coal, the divergence in utility grades suggests that some providers are beginning to prioritize renewable diversification. Homeowners may find it beneficial to stay informed about their provider's energy sourcing, as these strategic shifts directly influence future service reliability and costs.
