In short: Kentucky homes pay less than most for power, 13.81¢ per kWh in July 2026, but lost about 648 minutes of power per customer in 2024, more than ten hours, and about three-quarters of that came on major storm days (EIA). In Kentucky, backup power is the first decision; solar is a slower, longer-term one.
Those two numbers pull in different directions. Cheap electricity stretches out the payback on solar, while long storm outages make a good backup plan worth more. Here’s how Kentucky’s own data lines up, from Louisville to the eastern mountains.
Kentucky at a glance
- Home electricity price: 13.81¢/kWh in July 2026 (13.13¢ in July 2025); 14.27¢ average for January to July 2026. U.S. average 18.31¢ (EIA, preliminary).
- Outages (2024): about 648 minutes per customer with major events, 153 without; about 2.0 interruptions a year, 1.3 without major events (EIA-861).
- Sun: about 4.05 kWh/m² per day in Louisville (NASA POWER, 2001–2020); rough estimate about 1,180 kWh per kW of panels per year.
- Net metering: net billing. Under SB 100 (2019) the Public Service Commission sets each utility’s export credit in rate cases; LG&E’s has been about 7.1¢ and KU’s about 7.5¢ per kWh. Systems up to 45 kW.
- Plug-in solar law: none found as of October 2, 2026.
- EVs and charging: 20,700 battery-electric and 8,600 plug-in hybrids registered through 2025; 1,189 public ports at 409 locations, 460 of them DC fast (AFDC, October 2026).
- Main utilities: Kentucky Utilities (about 547,000 customers), Louisville Gas & Electric (about 438,000), Kentucky Power (about 163,000) and Duke Energy Kentucky (about 154,000) (EIA-861, 2024). Many rural areas are served by electric co-ops.
- Weather risk (FEMA National Risk Index, Dec 2025): winter weather, ice storm, cold wave, tornado and strong wind all relatively high; heat wave relatively moderate; wildfire relatively low.
- Public Safety Power Shutoffs: no program found at LG&E/KU, Kentucky Power or Duke Energy Kentucky.
Backup power in Kentucky
Kentucky’s 648 minutes ranked 11th-highest among the 50 states and D.C. in EIA’s 2024 data. On normal days the figure was 153 minutes, so roughly 495 minutes per customer came from major events. Put another way: an average interruption in 2024 lasted more than five hours once storms are included. Five hazards are rated relatively high by FEMA here, from ice storms and winter weather to tornadoes and strong wind, so outages can come in any season.
With outages that long, a few hours of battery isn’t enough for many households. A practical way to choose:
- You mostly need the fridge, lights, phones and internet: a large portable power station, ideally with solar panels to recharge during a multi-day outage. Check run time in the battery backup calculator.
- You need heat, a sump pump or a well pump for a day or more: a portable generator through a transfer switch or listed interlock kit, installed by a licensed electrician. Size it with the generator sizing tool.
- You want it automatic: a standby generator on natural gas or propane, or a whole-home battery sized for your critical circuits.
Generators save lives in long outages and take them when misused. CPSC’s rules: outdoors only, at least 20 feet from the house, exhaust pointed away from windows, doors and vents, never in a garage, basement or carport, and battery-backed CO alarms on every level. Never plug a generator into a wall outlet.
Solar in Kentucky
The honest picture: solar in Kentucky is a long-term investment. By our rough estimate, each kW of panels makes about 1,180 kWh a year in Louisville-like sun. Power you use yourself saves about 14¢ a kWh at the July 2026 rate, while power you export earns a lower credit, reported at about 7.1¢ at LG&E and 7.5¢ at KU. So each kW is worth roughly $85 to $165 a year depending on how much you use at home versus export. That’s an estimate, not a quote.
To push your result toward the top of that range:
- Size panels to your daytime use rather than your whole annual bill.
- Run the dishwasher, laundry, water heater timers or EV charging when the sun is out.
- Ask your utility for its current export rate. Under SB 100 each utility’s credit is set in its own rate case, so it differs between LG&E, KU, Kentucky Power, Duke Energy Kentucky and the co-ops, and it can change.
We didn’t confirm any state solar incentive for Kentucky, and the federal residential credit ended for systems completed after December 31, 2025, so price quotes on their own merits. Kentucky has no plug-in solar law; plug-in kits fall under your utility’s interconnection rules. Learn more in our solar guide, solar costs and net metering and net billing, and use the solar potential calculator.
Home batteries in Kentucky
Of 10,069 net-metered home solar systems in EIA’s 2024 count, 476 had a battery, close to 5%. In Kentucky a battery earns its keep in two ways: it stores solar that would otherwise be exported for about half the retail price, and it keeps the house running during those long storm outages. The second reason is usually the stronger one. If a multi-day outage is your worry, pair the battery with solar or a generator so it can recharge. We didn’t confirm a state battery program. See home batteries and battery costs.
EV charging in Kentucky
Kentucky had 20,700 battery-electric vehicles through 2025 and 1,189 public ports, 460 of them DC fast. Low power prices make home charging among the cheapest in the country: using about 30 kWh per 100 miles (a typical fueleconomy.gov-style figure), 100 miles costs roughly $4.14 at the July 2026 rate, or about $41 for 1,000 miles. That’s an estimate; cold weather and your car change it. Use the EV charging cost calculator and read EV charging at home. Level 2 charging needs a 240 V circuit by a licensed electrician with a permit. The federal charger credit ended for chargers placed in service after June 30, 2026, and we didn’t confirm a Kentucky charger rebate.

Off-grid, small wind and micro-hydro
Kentucky’s wind is weak for small turbines. NASA’s coarse average near the state center is about 4.9 m/s at 50 meters but only about 2.8 m/s at 10 meters, where small turbines actually sit, well below the 4.5 m/s the U.S. Department of Energy’s small wind guidebook suggests. Only a measured, exposed ridge might work. For hollows and remote cabins, solar with batteries and a generator backstop is the realistic off-grid setup. We haven’t checked a state source on micro-hydro, so we make no claims about it. See off-grid power, wind energy and hydroelectric power.
Licensing and permits in Kentucky
Kentucky licenses electrical contractors and master electricians statewide through the Department of Housing, Buildings and Construction (HBC), Division of Electrical. There’s no separate solar license, so solar and battery installers need the electrical license. Search the HBC licensee list before you sign. Permits and inspections are handled locally or by the state depending on where you live; the installer should pull them. Your utility must approve interconnection before solar or a battery goes live.

Kentucky energy FAQ
Does Kentucky have net metering?
Kentucky uses net billing. Since SB 100 (2019), the Public Service Commission sets each utility’s credit for exported solar power in its rate cases, below the retail price. LG&E’s export credit has been about 7.1¢ per kWh and KU’s about 7.5¢. Systems up to 45 kW qualify. Ask your own utility or co-op for its current rate.
Why are power outages so long in Kentucky?
In 2024, about three-quarters of Kentucky’s 648 outage minutes per customer came on major event days, according to EIA. FEMA rates ice storms, winter weather, tornadoes and strong wind as relatively high risks for the state, and those events can damage many lines at once. Normal-day outages were a more modest 153 minutes.
Is solar worth it in Kentucky?
It can be over the long run, but payback is slower than in most states because power is cheap and exports earn about half the retail rate. By our estimate each kW of panels is worth roughly $85 to $165 a year. Solar paired with a battery makes the strongest case when backup during long outages also matters to you.
How do I check a Kentucky electrician’s license?
Use the licensee search of the Kentucky Department of Housing, Buildings and Construction, which licenses electrical contractors and master electricians statewide. Kentucky has no separate solar license, so a solar or battery installer should hold the electrical license or work under a licensed electrical contractor.
