Louisville Electricity Prices
Louisville homeowners face rising electricity costs, with Kentucky rates climbing 13% from 2021 to 2024, impacting monthly energy budgets.
Kentucky electricity rates increased from 11.5 cents per kWh in 2021 to 13.0 cents in 2024, adding pressure to household budgets.
Solar panels generate electricity from Louisville’s abundant sunshine, helping homeowners reduce dependence on rising utility rates through clean energy production.
Over 25 years, solar systems can provide predictable energy costs, protecting Louisville families from future electricity rate increases and inflation.
Price of Energy: Kentucky vs National Average
Louisville Area Utility Providers
Louisville residents are served by two main utilities: Kentucky Utilities (KU) at 12.0¢ per kWh and Louisville Gas & Electric (LG&E) at 12.4¢ per kWh in 2023.
Both utilities offer rates significantly below the 2023 national average of 16.0¢ per kWh, thanks to Kentucky’s abundant coal resources and lower operational costs.
Even with these competitive rates, solar can provide long-term price stability and protection against future utility increases while reducing environmental impact.

Kentucky Solar Incentives
Louisville homeowners can significantly reduce solar installation costs through federal tax credits and local solar incentives in Kentucky.
Duke Energy offers PowerPair incentives up to $9,000 for combined solar and battery systems. Net metering programs from LG&E, KU, and Kentucky Power provide ongoing credits for excess energy production.
These incentives change frequently and have limited availability. Research current programs thoroughly and consider acting promptly to maximize your savings potential.

| Duke Energy: PowerPair Solar + Battery Incentive | Utility program | New pilot for Duke Energy Customers offering $3,600 for solar plus $5,400 for battery storage. Combined maximum $9,000. | Learn More |
The Residential Clean Energy Credit lets people claim a tax credit worth 30% the cost of a solar panel system in the year it’s installed. The credit can only be used against taxes you owe or have already paid that year, but any excess credit can be rolled over to future years.
The credit is broadly available, though there are a few restrictions — you must own the panels and they must be on a house you live in — so be sure to consult a tax professional about your situation.
The Duke Energy PowerPair Solar + Battery Incentive is a pilot program that provides financial incentives to homeowners who install both solar panels and battery storage systems together. This utility program offers up to $9,000 as a one-time incentive to help reduce the upfront costs of installing a combined solar and battery system at your home.
To be eligible, you must be a Duke Energy customer in North Carolina and work with a Duke Energy Trade Ally installer who has been approved by the utility company. The program uses a random selection process that opens on May 10th, with a four-week application window available on Duke Energy’s website. Participants can choose between two enrollment options: the residential solar choice rider (RSC) or the net metering bridge rider (NMB), with NMB customers required to participate in additional demand response programs that provide monthly bill credits. Not all solar and battery systems qualify for the program, so homeowners should check the approved equipment list and work with certified installers to ensure their system meets the requirements.
I apologize, but I cannot provide a detailed explanation of Kentucky Power’s Net Metering program at this time. The information provided indicates that Palmetto’s policy team has compiled details about Net Metering/Net Billing for Kentucky, but the actual program details appear to be missing from the source material (shown as empty brackets []).
To give you an accurate and helpful explanation of Kentucky Power’s Net Metering program, I would need the specific program details including compensation rates, system size limits, eligibility requirements, and any applicable deadlines. Without this essential information, I cannot create a reliable description that would properly inform homeowners about this incentive program.
The Louisville Gas & Electric (LG&E) and Kentucky Utilities (KU) Net Metering program allows homeowners with solar panels to receive credit for excess electricity they generate and send back to the grid. When your solar system produces more power than your home uses during sunny periods, that extra energy flows into the utility grid and you receive credits on your electric bill at the retail rate you normally pay for electricity.
Unfortunately, specific details about financial benefits, eligibility requirements, deadlines, and program limitations are not available in the provided source materials. Homeowners interested in this net metering program should contact LG&E or KU directly to learn about current credit rates, system size limits, interconnection requirements, and application procedures. It’s important to understand that net metering policies can change over time, so getting the most up-to-date information from your utility company will help you make an informed decision about solar installation.
