Kentucky Utility Cost Calculator

Coal is still the base

Kentucky is one of five states where coal still produced most of the electricity in 2024 — 67%, down from 92% in 2014 — with natural gas at 26% and hydro at 6%. Kentucky Utilities’ Ghent station was the largest generator. Cheap fuel shows in the price: Kentucky’s 2024 all-sector average ranked 40th of 51, and homes paid 13.92¢ per kWh over the last year.

Utilities, co-ops and TVA

Kentucky Utilities (5.9 TWh to homes), Louisville Gas & Electric (4.2 TWh) and Kentucky Power (1.9 TWh) are the investor-owned utilities regulated by the Kentucky Public Service Commission. Cooperatives made 35% of retail sales, the fifth-largest cooperative share in the country, and serve about 892,000 accounts; Kenergy is the biggest. The Tennessee Valley Authority is among the five largest retailers, but EIA records no residential sales by TVA in Kentucky.

A winter-peaking electric bill

Unusually for the South, Kentucky’s average electric bill was highest in winter: $208.92 in January 2026, against $116.72 in October 2025. Nearly half of homes (49%) heat mainly with electricity, and the 2020 survey found 4,172 kWh a year of electric space heating in homes that use it. Homes also use a lot overall — about 1,107 kWh a month, fifth-most in the country.

EIA collects heating oil ($4.872 a gallon) and propane ($2.936) prices in Kentucky, both from the last week of the 2025–26 season. LIHEAP is run by the Division of Family Support in the Cabinet for Health and Family Services.
