Frankfort Electricity Prices
Electricity rates shape household budgets, and statewide data offers Frankfort homeowners useful context for considering solar.
Kentucky’s average residential rate rose from 11.5¢ per kWh in 2021 to 13.0¢ in 2024, despite a small dip in 2023. The U.S. average climbed from 13.7¢ to 16.5¢ over the same period.
For Frankfort homeowners, a purchased solar system can generate some electricity at home and reduce how much is bought from the utility. The effect depends on system output, household use, and local utility billing rules.
When purchased outright, panels are the homeowner’s asset, and the homeowner keeps any utility-bill savings. Over time, solar may help offset rising rates, though results depend on system cost, output, and future electricity prices.
Price of Energy: Kentucky vs National Average
Frankfort Area Utility Providers
In Frankfort, Kentucky Utilities (KU) is the provider shown in the latest available comparison. The 2023 figures put KU electricity at 12.0¢ per kWh, below Kentucky’s 12.70¢ and the national average of 16.0¢.
These are 2023 rates; 2024 utility data is not yet available. The figures show KU’s rate was lower than both averages, but they do not explain why. State and national averages are comparison points, not KU-specific rates.
For Frankfort homeowners, a purchased solar system may offset some electricity bought from KU, though the amount depends on the home and system. Comparing solar production with household use can help show how utility rates affect potential bill savings.

Kentucky Solar Incentives
State and utility programs may help offset solar costs in Frankfort. Explore the solar incentives in Kentucky below.
Eligible Kentucky customer-generators may receive utility-specific bill credits for electricity exported to the grid. Credit value and rules depend on the utility tariff and service date.
Eligible LG&E/KU customers can subscribe to utility solar through Solar Share and receive associated bill credits without rooftop panels. These utility programs remain worth exploring.
| 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 |
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. Frankfort Plant Board and other Kentucky utilities have different tariffs, and battery operation can affect how much solar energy is used onsite versus exported.

How to Choose a Solar Installer in Frankfort
Verify the license
Kentucky’s current licensing materials do not identify a separate statewide solar-installer license. Electrical work generally must be performed by a Kentucky-licensed electrical contractor, with statutory exceptions; an electrical-permit applicant must show they are licensed or acting on behalf of a licensed electrical contractor. Look up a contractor through the Kentucky Department of Housing, Buildings and Construction (DHBC) licensee search. Ask which licensed contractor is responsible for the electrical work and permit, especially if the salesperson or installation crew is a different company.
Look for certified installers
Ask whether the people designing and installing your system hold a relevant NABCEP certification, and verify who holds it and what work it covers. Ask about manufacturer certifications for the specific panels and inverters in your proposal, too. These credentials can help you assess relevant training or product familiarity; they are not a substitute for any required Kentucky electrical license. Compare credentials alongside references, contract terms and the actual equipment proposed.
Compare quotes the same way
Request written proposals with the same information so you can compare scope, equipment and cost—not just the headline payment.
- System size in kilowatts (kW) and price per watt; check that the quotes use comparable system sizes.
- Panel and inverter brands and models, plus the estimated annual production in kilowatt-hours (kWh/year). Ask what assumptions the estimate uses and whether it is a guarantee.
- Warranty terms and who backs them: panel product and performance, inverter, workmanship, and roof penetrations.
- Who is responsible for permits, inspections and the utility interconnection application, and whether those tasks are included in the quoted scope.
- Total cost, or monthly payment if applicable, and any payment escalator. Compare the full payment schedule, not just the first payment.
Permits, interconnection and your HOA
Start by asking your city or county building department which permits and inspections apply at your address. Local governments issue building permits within their building-code jurisdiction; single-family permits and inspections are not mandatory statewide unless a local government has adopted an ordinance requiring them. An electrical permit is required before covered electrical work begins. The local certified electrical inspector handles this where available; otherwise DHBC handles state-inspection work and electrical inspections. The homeowner applies to the serving utility for interconnection and must receive approval before connecting. Depending on your address, the utility may be Kentucky Utilities Co, Louisville Gas & Electric Co, Duke Energy Kentucky or Kentucky Power Co; check its current tariff and application requirements. Kentucky law allows a property owner to obtain a written easement for direct sunlight, but no statewide law was found that overrides an HOA ban on rooftop solar. Review your HOA rules before signing.
Red flags
- Pressure to sign the same day, or discouraging you from comparing written proposals.
- An unlicensed electrical contractor or out-of-state crew whose licensed Kentucky electrical contractor and responsibilities cannot be clearly identified.
- Vague production estimates, unclear warranty responsibility, or a large upfront deposit without a clear written payment schedule.
- Promises of federal homeowner tax credits for purchases in 2026: the homeowner credits ended December 31, 2025. For contractor sales, contract or workmanship complaints, contact the Kentucky Attorney General’s Office of Consumer Protection; utility interconnection or net-metering complaints belong with the Public Service Commission.
Frequently Asked Questions
Yes. Eligible Frankfort-area homeowners can receive utility bill credits for excess solar electricity sent to the grid under Kentucky’s net-metering law. Newer customers generally receive credits based on their utility’s applicable rate; the credit is not automatically a one-for-one match for each kilowatt-hour exported.
Rates and connection rules depend on your provider and tariff. Check with your utility—such as Kentucky Utilities or the Frankfort Plant Board—before sizing a solar system.
Yes. In Frankfort, an outright-purchased solar panel system may increase a home’s resale value. A Zillow study found homes with solar panels sold for about 4.1% more on average, though this is not guaranteed for every property.
When you own the system, any added resale value belongs to you. The actual impact can vary with system condition, energy production, utility rules, and buyer demand in Central Kentucky.
In Frankfort, buying a solar system outright typically costs about $16,900–$27,500, or roughly $3.08–$3.28 per watt. A typical 6.8 kW system is estimated at $21,521 ($3.16 per watt).
The federal 30% residential solar tax credit was eliminated by the 2025 federal law change, so it is not included. See the solar cost calculator above for estimates by home size; your actual price depends on your home and system design.
Solar can make sense in Frankfort, where homes average about 4.7 peak sun hours daily. Kentucky’s average residential rate was 13.0¢/kWh in 2024; Kentucky Utilities’ reported 2023 rate was 12.0¢/kWh.
A typical 6.8 kW purchased system is modeled to cover about 100% of average household electricity use and reduce bills by roughly $83 per month. Actual savings depend on roof conditions, energy use, and utility rules; fixed charges and lower credits for exported power may leave a bill.
Solar can be financially worthwhile in Frankfort when the system’s lifetime bill savings exceed its purchase and upkeep costs. For a typical 6.8 kW system, the article estimates a $21,521 cost, a 16.7-year payback period, and about $36,268 in savings over 25 years.
When you own the system, you keep the financial benefit of the electricity it produces, including bill savings and utility credits for exported power. Actual results depend on your roof, energy use, system output, and KU’s current credit rules.
A typical 6.8 kW solar system in Frankfort could produce about 9,000 kWh of electricity per year. This estimate is based on the article’s local NREL production figures for 7 kW systems.
Actual output varies with roof direction and pitch, shading, and weather. Frankfort systems generally produce more during long summer days and less in winter, when days are shorter and cloud cover can reduce sunlight.
