Overview

Kentucky, home to the nation's gold reserves at Fort Knox and the popular Kentucky Derby horse race at Churchill Downs in Louisville, became the first state west of the Appalachian Mountains in 1792.1 Bordered on the north by the Ohio River, Kentucky stretches from the Appalachian Mountains in the east to the flood plain of the Mississippi River in the west.2 In between, the rolling hills of the state's fertile Bluegrass region extend southward from the Ohio River to the Pennyroyal region, which is famous for its thousands of caverns and springs, including Mammoth Cave National Park.3,4 Major coal deposits are found both in the Central Appalachian Basin in the eastern part of the state and in the Illinois Basin in the northwest.5 Those basins also contain crude oil and natural gas reserves.6,7,8 Dams on the Tennessee, Cumberland, Ohio, and Laurel rivers provide Kentucky with hydroelectric power.9 Although two-thirds of Kentucky's agricultural economy is livestock, primarily thoroughbred horses and beef cattle, the state's ample rainfall, temperate climate, and fertile soils provide ideal conditions for growing several crops, including tobacco, soybeans, corn, and wheat.10,11,12 Corn and beverage waste from Kentucky distilleries provide feedstock for the state's fuel ethanol production.13,14

Kentucky has an energy-intensive economy, and ranks 12th among the states in the amount of energy used per dollar of GDP.15 The industrial sector is the state's largest energy consumer, accounting for about 36% of total end-use energy consumption.16 The manufacture of food, beverage, and tobacco products; motor vehicles; primary and fabricated metal products; and chemicals are major contributors to the state's GDP, as are agriculture and forestry. Coal mining and petroleum refining are two of Kentucky's energy-intensive industries.17 The transportation sector makes up about 30% of the state's energy consumption, followed by the residential sector at about 20%, and the commercial sector accounts for about 14% of state energy use.18

Coal

Kentucky is the fifth-largest coal producer among the states.

Kentucky ranks fifth in the nation in estimated recoverable coal reserves and fifth in coal production.19,20 Coal was mined in Kentucky as early as 1790. Since then, nearly 10 billion tons of coal have been mined in the state.21,22 About three-fifths of Kentucky's coal mines are surface mines, but underground mines account for about 80% of the state's coal production.23 The state's mines produce only bituminous coal, which is the most abundant type of coal found in the United States and is used for producing electricity, iron, and steel.24,25 For many years, Kentucky was the third-largest coal-producing state, after Wyoming and West Virginia, and typically accounted for about one-tenth of total U.S. coal production.26 However, Kentucky's coal production declined in response to demand as U.S. coal-fired electricity generating plants shut down and generation from renewables and natural gas increased.27,28,29,30 In 2020, Kentucky's coal production declined to its lowest level since 1915. Although the state's coal output increased in 2021 and 2022, it accounted for slightly less than 5% of total U.S. production.31,32,33,34 Still, about one out of five U.S. operating coal mines are located in Kentucky, and it has more mines than in any other state except for West Virginia and Pennsylvania.35

Kentucky plays an important role in the benchmark prices for eastern U.S. coal, which are determined in the Central Appalachian (CAPP) coal delivery zone located near where the Big Sandy River flows into the Ohio River. Kentucky meets Ohio and West Virginia at the rivers' confluence, and coal is delivered to the CAPP from mines in those three states, as well as from Virginia and Tennessee. The coal arrives by rail or truck for transport on multi-car trains and barges to customers—including coal-fired electricity generating plants, industrial plants, commercial and institutional facilities, and coking plants—throughout the country.36

About 85% of Kentucky's coal stays in the United States, with about two-fifths of that coal remaining in Kentucky. The rest of the coal is sent to nearly 20 other states, where it is burned primarily by power plants to generate electricity.37,38 Kentucky ranks among the top 10 states in coal consumption, and nearly all that coal is used for electricity generation. In 2021, about 37% of Kentucky's coal needs were met with the state's own coal, and the remaining coal consumed in Kentucky was brought in from other states, primarily Wyoming, Illinois, and West Virginia.39,40,41

Electricity

In 2022, coal generated 68% of Kentucky’s in-state electricity, a larger share than all but two other states.

In 2022, coal-fired power plants supplied 68% of Kentucky's electricity generation, the third-largest share among the states after West Virginia and Wyoming.42,43 Historically, coal-fired power plants produced more than 90% of Kentucky's net generation. However, as older coal-fired generating units became more costly to operate, about 5,600 megawatts of coal-fired generating capacity shut down over the past decade.44,45,46,47 Kentucky remains among the top 10 states in the nation in coal-fired generating capacity with about 9,400 megawatts at the beginning of 2023.48

Natural gas provides an increasing amount of Kentucky's net generation. In 2022, natural gas-fired power plants generated 25% of the state's electricity, more than double the share from five years earlier. The rest of Kentucky's electricity generation, less than one-tenth, came mostly from hydroelectric power plants, along with small contributions from biomass, solar energy, and petroleum-fired generation.49

In 2022, Kentucky had the 18th-lowest average electricity price of any state and the third-lowest price east of the Mississippi River.50 Slightly more than half of Kentucky households use electricity as their primary heating source.51

Petroleum

Kentucky accounts for less than 0.1% of U.S. proved crude oil reserves and production.52,53 Half the state's counties have producing oil wells, and the highest producing areas are located in eastern and western Kentucky.54,55 Kentucky's oil production of nearly 2.3 million barrels in 2022 was less than one-third of the state's record oil production of 7.9 million barrels in 1983. The state's annual oil production has been less than 3 million barrels every year, except for one, during the past three decades.56

Kentucky has one oil refinery that can process up to 291,000 barrels of crude oil per calendar day.

Kentucky has one operating crude oil refinery, located in the city of Catlettsburg in northeastern Kentucky. It is the 15th largest U.S. refinery and can process 291,000 barrels of crude oil per calendar day to make motor gasoline, distillates, asphalt, heavy fuel oil, and propane. The Catlettsburg refinery accounts for about 1.6% of U.S. refining capacity.57,58 A smaller refinery located in the city of Somerset in southeastern Kentucky, which could process about 5,500 barrels of crude oil per calendar day, closed in 2020 for economic reasons. The refinery's owner is converting the facility to process soybeans to produce biodiesel.59,60,61 Additional refined petroleum products arrive in the state via interstate pipelines and by river barges at Kentucky ports along the Ohio River.62,63,64

The transportation sector accounts for three out of every four barrels of petroleum consumed in Kentucky, and motor gasoline accounts for about two-fifths the state's total petroleum use.65,66 Conventional motor gasoline can be sold statewide, except for in all or part of three counties around Louisville that allow only reformulated gasoline blended with ethanol to reduce air pollution. In July 2018, with the approval of the federal government, the state withdrew three of its counties that make up the southern suburbs of Cincinnati from the federal reformulated gasoline program.67,68,69 The industrial sector accounts for about one-fifth of the petroleum consumed in Kentucky. The rest of the small amount of petroleum used in the state is split almost equally between the commercial sector and the residential sector, where about 7 out of 100 Kentucky households heat with propane, fuel oil, or kerosene.70,71

Natural gas

Kentucky holds about 0.2% of U.S. proved natural gas reserves, but organic-rich shales that underlie eastern Kentucky may hold substantial additional natural gas resources.72,73,74 The state accounts for about 0.2% of the nation's marketed natural gas production.75 Most of the state's natural gas is produced from wells located in eastern Kentucky.76,77 The state's annual natural gas production increased in the early 2000s, peaking in 2010 at about 135 billion cubic feet, but has declined about two-thirds since then. However, in 2021, the state's natural gas output increased for the first time since 2005, rising to 75 billion cubic feet as natural gas prices and demand rose.78,79,80,81

Kentucky’s 22 underground storage facilities can hold almost 222 billion cubic feet of natural gas.

Consumption of natural gas in Kentucky is almost five times greater than the state's production, and several interstate natural gas pipelines bring natural gas supplies to Kentucky consumers.82,83,84 For more than two decades, most of the natural gas that entered Kentucky arrived by pipeline from the U.S. Gulf Coast. However, starting in 2015, Kentucky began to receive more natural gas produced in the Utica and Marcellus shale formations in Pennsylvania, Ohio, and West Virginia. In 2021, about three-fourths of the natural gas transported by pipeline to Kentucky came from Ohio and West Virginia. About 90% of the natural gas that entered Kentucky was sent on to other states, primarily Tennessee and Indiana.85 Some natural gas stays in Kentucky in underground storage. The state has 22 underground natural gas storage facilities that can hold nearly 222 billion cubic feet of gas—about 2% of U.S. total storage capacity.86,87

In 2022, Kentucky's electric power sector consumed record volumes of natural gas and accounted for 39% of the natural gas used in the state. Natural gas consumption by the sector more than doubled the level from six years earlier. The industrial sector also consumed record natural gas, making up 37% of natural gas use. The residential sector, where about one-third of Kentucky households use natural gas for home heating, received about 14% of the natural gas delivered to end users in the state. The commercial sector accounted for about 11% of state natural gas consumption. A minor amount of natural gas is used in the transportation sector.88,89 Kentucky's per capita natural gas use is less than in two-fifths of the states.90

Renewable energy

Renewable resources are a relatively small part of Kentucky's energy mix. Hydropower accounts for nearly all of the state's renewable electricity generation. In 2022, 11 hydroelectric dams produced about 6% of the state's total electricity net generation.91,92 Almost one-tenth of the renewable generation in Kentucky, or about 0.6% of the state's total generation, came from biomass.93 Most of the biomass-fueled electricity generating facilities in Kentucky use landfill gas. However, the largest biomass facility—with 49 megawatts of capacity and accounting for two-thirds of the state's total biomass generation capacity—uses wood waste.94 The state's biomass resources include its forests, which provide feedstock for two wood pellet manufacturing plants that have a combined production capacity of 80,000 tons a year.95 About 2% of Kentucky households heat with wood.96

Kentucky has both utility-scale (1 megawatt or larger) and small-scale (less than 1 megawatt), customer-sited solar power generation facilities, which together accounted for 0.2% of the state's total electricity generation in 2022.97 The state's largest utility-scale solar photovoltaic (PV) generating facility is a 50-megawatt solar farm that came online in late 2022 south of Lexington. A 55-megawatt solar farm is scheduled to come online in the second half of 2023.98 Kentucky has few wind resources suitable for utility-scale power projects, and there are no commercial wind power facilities in the state.99,100

Kentucky has two fuel ethanol production plants with a combined capacity of about 53 million gallons per year.101 A plant owned by a farmers' cooperative produces most of the ethanol, using corn as its primary feedstock.102 The smaller ethanol plant is a recycling operation in a former bourbon distillery in Louisville that produces ethanol from waste non-alcoholic and alcoholic beverages; sugars; industrial alcohols; health and beauty alcohols (mouthwash and perfumes); and pharmaceutical manufacturing by-products.103 The state's annual ethanol consumption of 217 million gallons is more than four times greater than the 48 million gallons produced. Kentucky has one biodiesel production plant, which makes about 39 million gallons per year, 50% more the state's annual biodiesel consumption of about 26 million barrels.104,105,106

Kentucky does not have a renewable portfolio standard to require a certain amount of the state's electricity to be generated by renewable sources. However, state law provides for net metering of small-scale renewable generation from solar, wind, hydro, biomass, and biogas facilities of 45 kilowatts or less. Each investor-owned utility and rural electric cooperative's obligation to connect eligible small-scale generators is limited to 1% of the power provider's peak single-hour electricity load during the previous year.107 Kentucky also provides financial incentives to companies that invest at least $1 million in a renewable energy facility that generates at least 50 kilowatts of electricity from solar energy or at 1 least megawatt of electricity from wind energy, biomass, landfill gas, hydropower, or similar renewable resources.108
