Lexington Electricity Prices
Electricity rates can change over time, making the cost of powering a Lexington home worth a closer look.
The chart shows Kentucky’s average rate rising from 11.5¢ per kilowatt-hour in 2021 to 13.0¢ in 2024, despite a small dip in 2023. These are statewide figures, not Lexington-specific rates.
A purchased solar system can generate some of a home’s electricity, reducing how much power its residents need to buy from the utility. For solar installation in Lexington, KY, output depends on roof conditions and household use; see our guide to home solar panels.
Over time, owning a system may help limit exposure to changing utility rates. Its long-term value depends on installation cost, how much electricity it produces and how household needs change; savings aren’t guaranteed.
Price of Energy: Kentucky vs National Average
Lexington Area Utility Providers
In Lexington, Kentucky Utilities serves local customers. Its average electricity rate was 12.0¢ per kilowatt-hour in 2023, the latest utility data available.
For context, Kentucky’s average rate was 12.70¢ per kilowatt-hour in 2023, compared with the national average of 16.0¢. Kentucky Utilities’ rate was below both benchmarks.
A home solar system can provide some electricity on site, which may reduce how much a household relies on utility power. The impact depends on the home’s energy use and system output.

Kentucky Solar Incentives
Kentucky utility bill credits and a solar subscription may be relevant to eligible Lexington-area customers. Explore the solar incentives in Kentucky below.
Eligible Kentucky customer-generators may receive utility-specific credits for electricity sent to the grid; credit values and rules vary by utility tariff and service date. Eligible LG&E/KU customers can also subscribe to utility solar and receive bill credits.
The federal 30% residential tax credit was eliminated by the Big Beautiful Bill. Kentucky utility programs may still offer benefits, so eligible customers can review the available options.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Kentucky Net Metering / Net Billing | Net Metering / Utility Bill Credits | Eligible Kentucky customer-generators can receive utility-specific bill credits for electricity exported to the grid, with credit value and rules depending on the utility tariff and service date. | Learn More |
| LG&E/KU Solar Share | Utility Solar Subscription | Eligible LG&E/KU customers can subscribe to a share of utility solar generation and receive associated bill credits without installing rooftop panels. | Learn More |
Kentucky’s net-metering law allows eligible customer-generators to receive bill credits for electricity sent to the grid. The statewide statutory system-size limit is 45 kW, but the value of exported power is set by the serving utility’s tariff, so there is no single statewide credit rate. For systems seeking net-metering credits, eligibility applies only to systems you purchase and own.
Legacy customers covered by the statutory transition rules may retain the tariff provisions in place when service began, including 1:1 kWh credits, for up to 25 years at the premises. Newer customers generally receive dollar-denominated credits at their utility’s applicable rate. Credits may carry forward, but are not cash-refundable when an account closes; interconnection upgrades may also be charged to the customer.
Before choosing a system size or estimating savings, get your utility’s current export-credit rate, interconnection requirements, and battery rules in writing. LG&E/KU and other Kentucky utilities have different tariffs, and battery operation can affect how much solar energy is used onsite versus exported.
LG&E and KU customers may subscribe to a 250-watt share of utility solar generation. The published price is $5.55 per share per month, or a one-time, non-refundable payment of $799 per share for 25 years. The utility estimates that each share produces about 18–38 kWh per month, depending on conditions.
Subscribers receive bill credits tied to their share under the program terms. The utility does not describe Solar Share as an energy-savings program, so compare the subscription cost with the bill-credit terms before enrolling. This is a utility subscription rather than a rebate or a customer-owned rooftop system.
Monthly subscriptions require a 12-month commitment, and enrollment may depend on section availability. Check the utility’s current terms and enrollment status before signing up.

How to Choose a Solar Installer in Lexington
Verify the license
Kentucky has not identified a separate statewide solar-installer license in its current licensing materials. But electrical work generally must be performed by a Kentucky-licensed electrical contractor, and an electrical-permit applicant must be licensed or acting on behalf of a licensed electrical contractor, subject to statutory exceptions. Ask which contractor is responsible for the electrical work and verify that license through the Kentucky Department of Housing, Buildings and Construction license lookup. You can also ask your city or county building department what applies to your project. A solar-contractor bill was proposed, but its official record does not show it enacted.
Look for certified installers
Ask who will design and install the system, and whether the people doing the work hold relevant credentials. NABCEP offers professional certifications for the solar industry; you can learn about them at NABCEP. Certification can be one useful qualification to compare, but it does not replace checking the electrical contractor’s Kentucky license or reviewing the proposal. Ask whether the installer is certified by the manufacturers of the panels or inverters it proposes, and what that certification covers. Compare credentials alongside references, written warranties, and the company’s plan for handling service after installation.
Compare quotes the same way
Request itemized proposals with the same assumptions, then compare:
- System size in kilowatts (kW) and total price per watt.
- Panel and inverter brands and models, plus estimated annual production in kilowatt-hours (kWh/year) and the assumptions behind that estimate.
- Panel product and performance warranties, inverter warranty, workmanship coverage, and coverage for roof penetrations. Check who provides each warranty and how to make a claim.
- Who handles permits, inspections, and the utility interconnection application.
- Total cost or monthly payment, any escalator, and any fees or other charges. Compare the same payment type and terms across proposals.
A lower price is not directly comparable if the system size, equipment, production estimate, or warranty coverage differs.
Permits, interconnection and your HOA
Start by asking your city or county building department which permits and inspections apply. An electrical permit is required before covered electrical work begins; the local certified electrical inspector handles this where available, otherwise state inspection may apply. You apply to your serving utility for interconnection and need its approval before connecting. Depending on your location, that utility may be Kentucky Utilities Co, Louisville Gas & Electric Co, Duke Energy Kentucky, or Kentucky Power Co. Ask the installer to explain who prepares and submits the paperwork, and check the utility’s current requirements. Kentucky law allows a property owner to obtain a written easement for direct sunlight, but it does not override an HOA’s ability to restrict or ban rooftop solar. Review your HOA rules before signing.
Red flags
- Pressure to sign the same day or a quote that discourages independent comparison.
- Unlicensed or out-of-state crews without a clear explanation of which Kentucky-licensed electrical contractor is responsible for covered electrical work.
- Vague production estimates, large upfront deposits, or promises of homeowner federal tax credits for purchases in 2026. Homeowner credits ended December 31, 2025.
