Utilities and rate plans
Each utility’s current residential tariffs, transcribed from its tariff sheets, with periods, tiers, fixed charge and a typical bill. Customer counts from EIA-861 (2025).
Cheapest utility for a typical Kentucky home (1,102 kWh a month) | Utility | Cheapest plan open to all | Typical bill | All-in ¢/kWh | Fixed/mo |
|---|
| KU | RTOD-Energy | $135 | 12.2 | $17.75 |
| LG&E | RTOD-Energy | $140 | 12.7 | $14.80 |
Each row prices a utility’s standard plan for a typical home. The Kentucky average of 13.95¢/kWh (EIA, 12 months) is what every household in the state actually paid, including utilities not modeled here and discounted low-income bills, so it can sit below every row.
Charging an electric car in Kentucky
Driving a Tesla Model Y Long Range AWD 1,000 miles a month takes 275 kWh from the wall (EPA 27.5 kWh/100 mi), about $38 at the state average. A 25.5 mpg gasoline car covering the same distance at $4.17 a gallon (Midwest (PADD 2) average, October 2026) costs about $163.
On a time-of-use plan, charging in the cheapest hours beats the flat average. The table shows, for each utility, the plan with the lowest total bill for a typical Kentucky home that adds 1,000 EV miles a month, averaged over the year, and what plugging in at 6 pm would cost instead.
| Utility | Best plan for an EV | Best start | 1,000 mi, best start | From 6 pm |
|---|
| KU | RTOD-Energy | 12 am | $20 | $31 |
| LG&E | RTOD-Energy | 12 am | $26 | $32 |

The state average hides the real spread. Utilities in the same state charge different prices, and on a time-of-use plan the same kWh costs more in the peak hours than off-peak; each utility page shows by how much. Open KU’s page to see its plans, prices by hour and fixed charge, or run the calculators below with Kentucky preloaded.
Natural gas for homes averaged $1.56 per therm over the 12 months to August 2026 (EIA, all charges included), and a typical gas-heated home uses about 470 therms a year for heating. The heat pump calculator compares that with electric heating on your plan.
A south-facing, 20° rooftop array in Kentucky produces about 1,351 kWh per installed kW a year (NREL PVWatts at the state’s population center). What that is worth depends on your utility’s export rule, shown on each utility’s page.
