Louisville Electricity Prices
If your LG&E bill keeps climbing, you’re not imagining it. Electricity costs in Louisville have steadily risen over the past few years.
Kentucky’s average electricity rate grew from 11.5 cents per kWh in 2021 to 13.0 cents in 2024. While still below the U.S. average, local rates continue trending upward year after year.
Solar gives Louisville homeowners a way to gain more control over these rising costs. By generating your own power, you rely less on the grid and become less exposed to future rate increases from your utility.
Over time, that stability can add up. Solar helps you plan your energy costs for years ahead. To understand how it works, explore our guide on home solar panels.
Price of Energy: Kentucky vs National Average
Louisville Area Utility Providers
In Louisville, most homes get power from LG&E or KU. Based on 2023 data, LG&E charged about 12.4¢ per kWh and KU about 12.0¢ per kWh—close to Kentucky’s 12.70¢ average and below the national average of 16.0¢.
These local rates stay lower than the 2023 national average largely because Kentucky’s electricity has long relied on regional coal and natural gas resources. Even so, area rates tend to rise gradually over time, which affects your monthly budget.
Understanding these costs helps explain why many neighbors consider solar panel installation. Solar installation can lock in more predictable energy costs, giving Louisville homeowners greater control as utility prices shift year to year.

Kentucky Solar Incentives
Several solar incentives in Kentucky can help Louisville homeowners lower the cost of going solar and get more value from their systems.
Kentucky’s net metering rules let LG&E and KU customers earn bill credits for extra power. Duke Energy Kentucky offers a solar-plus-battery rebate, and community solar programs provide credits without rooftop panels.
The federal 30% residential tax credit has ended, but state and local incentives remain. Leasing through LightReach also simplifies things, as Palmetto manages the commercial ITC and passes savings along.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Kentucky Net Metering Policy | Net Metering | Kentucky requires most utilities to offer net metering to solar customers, though compensation rates vary significantly by utility. | Learn More |
| LG&E and KU Solar Share Program | Community Solar | LG&E and KU Energy customers can subscribe to shares of a local community solar project and receive bill credits without installing panels on their property. | Learn More |
Kentucky state law requires all investor-owned utilities (IOUs) and electric cooperatives — excluding the Tennessee Valley Authority (TVA) — to offer net metering to customers with qualifying solar energy systems. The eligible system size has been increased from 30 kW to 45 kW under SB 100, and compensation rates are overseen by the Kentucky Public Service Commission (PSC). In Louisville, LG&E and KU Energy currently offer full retail net metering, meaning excess energy you send to the grid is credited at the same rate you pay for electricity — the best possible outcome for solar owners.
Because Louisville homeowners are served by LG&E or KU Energy, net metering remains a strong financial benefit for residents of Louisville installing solar in 2026.
The LG&E and KU Solar Share Program is a community solar option that allows residential, business, and industrial customers to benefit from solar energy without installing panels on their own property. This is an ideal solution for renters, homeowners with shaded or unsuitable roofs, or anyone who wants to support local solar generation without the upfront cost and maintenance of a private rooftop system.
Customers purchase shares of a local community solar project for less than 20 cents per day, with a monthly subscription fee of $5.55 per share and no start-up costs. In return, participants receive corresponding bill credits each month based on the energy their shares produce. The monthly fee may change over time, but only if approved by the Kentucky Public Service Commission.
The Solar Share Program is open to LG&E and KU Energy residential and business customers, including those in Louisville. It provides a straightforward, low-commitment way to participate in solar energy and reduce your effective electricity costs without any installation, permitting, or long-term maintenance responsibilities. Visit the official LG&E/KU Solar Share page to learn more and sign up.

Yes. Louisville homeowners are served by LG&E and KU Energy, and both utilities offer full retail net metering. This means the extra electricity your panels send to the grid is credited at the same rate you pay for power—the most valuable arrangement for solar owners.
Kentucky law requires utilities to offer net metering for qualifying systems up to 45 kW, with rates overseen by the Kentucky Public Service Commission. For Louisville residents, this keeps net metering a strong benefit in 2026.
Yes. In Louisville, solar panels can increase your home’s value when you own or purchase the system outright. A Zillow study found that homes with solar panels sell for approximately 4.1% more than comparable homes without them.
This value boost applies to owned systems, not leased ones. With a leased or LightReach system, resale works differently, since the buyer typically assumes the existing lease agreement rather than gaining added home value.
Louisville homeowners can go solar with no upfront cost through a LightReach lease, paying a low fixed monthly amount—starting around $87/month for a medium-sized home. Palmetto owns and maintains the system, so there’s no maintenance to worry about.
Prefer to buy? A cash purchase for an average home is about $21,500. Note that the federal 30% tax credit is no longer available for residential cash purchases after the 2025 law change. See the calculator above for pricing by home size.
With a solar lease through Palmetto’s LightReach program, you make one simple monthly payment that covers everything: the panels, installation, monitoring, maintenance, and a 90% Production Guarantee. There’s no upfront cost. For a typical 6.80 kW system in Louisville, the estimated payment is about $87/month.
Because Palmetto owns the system, it claims the commercial tax credit and passes those savings to you through lower payments. Since your lease payment is often less than your current LG&E bill, you can start saving from day one.
Yes. Louisville averages about 4.8 peak sun hours per day, which is enough for solar panels to work well in Kentucky’s climate. Panels still generate power on cloudy or humid days, just at a reduced rate, since they run on daylight rather than direct sun alone.
Because Louisville has four distinct seasons, production varies through the year. Sunny summer months bring the highest output, while shorter winter days produce less. A well-designed system captures plenty of energy across all seasons.
For many Louisville homeowners, solar makes financial sense because it replaces a rising LG&E or KU bill with more predictable energy costs. With a LightReach lease, you can start saving from day one, since your fixed monthly payment is typically less than your current electricity bill.
There’s no upfront investment required. Palmetto owns and maintains the system, so your savings begin the moment your panels switch on, without loans or maintenance costs to manage.
Solar panels are low maintenance and typically need only occasional cleaning, since Louisville’s rain often rinses them naturally. There are no moving parts to wear out.
With a LightReach lease, Palmetto owns the system and handles all maintenance, monitoring, and repairs at no extra cost. Your lease also includes a 90% Production Guarantee, so you can enjoy solar without worrying about upkeep.
