Kentucky Electricity Rates: What to Know

For decades, Kentucky has been one of the cheapest places in America to plug something in. Coal from the state's own mines fed a fleet of power plants that produced electricity at rock-bottom prices, and the average Kentucky household paid noticeably less than the national average. In 2024, Kentucky still had the lowest residential rates of any state east of the Mississippi, averaging around 10.18 cents per kilowatt-hour according to the U.S. Energy Information Administration. The typical monthly bill sat near $145, roughly 20% below the national average.

That era is ending faster than most Kentuckians realize. Since 2020, Kentucky electricity rates have climbed about 19% — a steady march upward driven by coal plant retirements, new natural gas generation, and an unprecedented surge in data center demand. LG&E and KU just won approval in February 2026 for fresh rate increases, Kentucky Power customers are absorbing their second hike in under a year, and Louisville is preparing to energize the state's first 400-megawatt hyperscale data center. Understanding what is driving the shift — and what you can do about it — is the key to keeping your bill manageable as Kentucky's low-cost advantage continues to erode.

How Kentucky's Electricity Market Works

Kentucky is a regulated electricity market. Unlike deregulated states where residents can shop for an electricity provider, Kentucky residential customers are served by whichever utility holds the franchise for their area. You do not get to choose.

The Kentucky Public Service Commission (KPSC), usually called the PSC, oversees more than 1,100 regulated utilities including investor-owned electric companies, electric cooperatives, water districts, and telecom providers. The PSC sets rates, approves major capital projects like new power plants, rules on integrated resource plans, and enforces service standards. The three-member commission is appointed by the governor and is the single most important body shaping what Kentuckians pay for electricity.

The PSC does not regulate municipal utilities — city-owned systems like Owensboro Municipal Utilities, Paducah Power System, Frankfort Plant Board, and Bowling Green Municipal Utilities set their own rates through local boards. The PSC also does not have jurisdiction over the far-western Kentucky counties served by the Tennessee Valley Authority (TVA), which operates under a separate federal framework.

Here is a quick breakdown of Kentucky's utility types:

Utility Type	Regulation	Examples
Investor-Owned Utilities (IOUs)	PSC-regulated	LG&E, KU, Kentucky Power, Duke Energy Kentucky
Electric Cooperatives	PSC-regulated	EKPC member co-ops, Big Rivers, Kenergy
Municipal Utilities	Self-governing	Owensboro, Paducah, Frankfort, Bowling Green
TVA-served areas	Federal	Far western Kentucky counties

Kentucky does not have community choice aggregation or any form of retail competition for residential customers. If you live in Louisville, your provider is LG&E. If you live in Lexington, it is KU. If you live in eastern coal country, it is probably Kentucky Power. Your main levers for controlling costs are not choosing a provider — they are managing usage, picking the right rate plan where options exist, and tapping into efficiency and assistance programs.

What Kentuckians Actually Pay

Let's put real numbers on the table. The average residential electricity rate in Kentucky in 2025 was approximately 13.14 cents per kWh, based on U.S. Energy Information Administration data. That is still well below the national average of roughly 16.73 cents, but the gap is narrowing every year. EnergySage's March 2026 figure, pulled from actual shared utility bills, puts Kentucky around 12 cents per kWh (EnergySage measures the all-in energy charge differently than EIA, which includes fixed fees).

The average monthly electric bill for a Kentucky household sits near $145 as of 2025, though this varies widely by utility. Louisville customers on EnergySage's platform report average monthly bills around $190, and customers in Kenton County (Duke Energy territory) report around $197. Rural Kentucky Power customers in the east pay the highest average bill of any major utility in the state — about $183 per month before the latest rate increase.

The trend is what matters most. Here is what the last five years of Kentucky's major rate changes look like:

Year	Event
2021	KY average residential rate: 11.5 cents/kWh
2021	Kentucky Power rate hike: +15.46% (~$18.59/month)
2022	Average KY electric bills rose ~17%
2024	KY average rate reaches 13.0 cents/kWh (13% increase in 3 years)
2025 (Jul)	Kentucky Power +6.37% (Big Sandy coal retirement)
2025 (Oct)	Duke Energy KY +10.04% (~$12.51/month increase)
2026 (Feb)	LG&E +$5.14/month, KU +$8.73/month (residential)
2026 (Mar)	Kentucky Power +5.87% first year, rising to 6.63% in 2027

Over the last five years, LG&E and KU residential energy rates have risen about 17-23%, while their fixed monthly service charges — the base fee you pay regardless of usage — have climbed roughly 50%. The state average bill is up about 19-20% since 2020, which still trails the national average increase of around 28%, but Kentucky's headroom is shrinking quickly. If your bill has been climbing and you are not sure where the money is going, our guide on how to read your electric bill and spot overcharges walks through every line item.

Major Utilities in Kentucky

Most Kentuckians are served by one of four investor-owned utilities or an electric cooperative tied to East Kentucky Power Cooperative or Big Rivers Electric. Here is how they compare.

LG&E (Louisville Gas and Electric)

LG&E serves roughly 431,000 electric customers across the Louisville metro area, primarily in Jefferson County and surrounding communities. It also provides natural gas to about 337,000 customers. Its parent is PPL Corporation, which operates LG&E jointly with sister utility KU under a shared management structure.

In February 2026, the Kentucky PSC approved LG&E's latest rate case, allowing an average residential electric bill increase of $5.14 per month — less than half of the $11-plus per month LG&E originally requested. The utility also gained approval to raise average residential gas bills by about $8.27 per month. Importantly, LG&E and KU agreed to a base-rate "stay out" until August 1, 2028, meaning they will not seek another general rate increase before that date. Customers who were billed at higher interim rates starting January 1, 2026 received credits on subsequent bills.

KU (Kentucky Utilities)

KU serves approximately 555,000 customers across much of central, western, and southeastern Kentucky outside the Louisville core, stretching through Lexington, the Bluegrass region, and down into Appalachian foothills. Together, LG&E and KU serve roughly one million electric customers in 77 of Kentucky's 120 counties.

KU's February 2026 rate case result was an $8.73 monthly increase for the average residential customer — less than half of the $18 per month KU originally sought. The same stay-out agreement through August 2028 applies. KU and LG&E are also the utilities behind Kentucky's most significant generation buildout plan, which we will cover in detail below.

Kentucky Power (AEP Subsidiary)

Kentucky Power, a subsidiary of American Electric Power (AEP), serves about 165,000 customers across 20 counties in Eastern Kentucky — the heart of Appalachian coal country. Its customers have historically paid the highest residential electricity rates in the state because of rural service territory, low customer density, and the high cost of maintaining a sprawling rural distribution network.

Kentucky Power customers have been hit with consecutive rate increases. A 6.37% jump took effect in July 2025 following the retirement of the Big Sandy coal plant. Then in February 2026, the PSC granted an additional 5.87% first-year increase as part of a new rate case, stepping up to 6.63% in 2027 — an average $10.76 per month bill increase. The original request was for a 14.62% revenue increase, and the Kentucky Attorney General publicly opposed the hike, arguing that "Kentucky Power reliably turns a profit." The PSC's trimmed approval was a partial win for customers but still a meaningful bill increase for a region where household incomes are among the lowest in the state.

Duke Energy Kentucky

Duke Energy Kentucky serves about 149,000 customers in Northern Kentucky — Kenton, Boone, Campbell, and parts of Grant, Pendleton, and Gallatin counties. Its territory covers the Kentucky side of the Cincinnati metro area.

In October 2025, the PSC approved a 9.61% revenue increase for Duke Energy Kentucky, resulting in an average 10.04% bill increase. The residential energy charge rose from $0.111639 per kWh to $0.122399 per kWh, with a fixed monthly customer charge of $14.75. The typical 1,000 kWh bill went from $124.64 to $137.15. That was Duke's first Kentucky rate adjustment since 2022. Duke Energy Kentucky was also the first utility in the state to formally transition away from full retail net metering — a change that matters if you are considering solar, which we will get to below.

Electric Cooperatives

About one in every three Kentucky households is served by an electric cooperative rather than an investor-owned utility. Cooperatives are member-owned and typically operate at cost rather than for shareholder profit, which can mean lower rates in some circumstances.

East Kentucky Power Cooperative (EKPC) is a not-for-profit generation and transmission (G&T) cooperative based in Winchester. It is owned by 16 member distribution cooperatives — including Blue Grass Energy, Jackson Energy, South Kentucky RECC, Nolin RECC, and many others — which together serve more than one million Kentuckians across most of central and southern Kentucky.

Big Rivers Electric Corporation, headquartered in Henderson, is a G&T cooperative serving three distribution co-ops in Western Kentucky: Kenergy Corp, Jackson Purchase Energy, and Meade County RECC. Together they cover 22 western counties.

Cooperative rates vary by member system, but are generally comparable to or slightly higher than LG&E/KU rates. Co-op members get to vote for board members and have a direct say in how their utility is run.

Why Kentucky's Low-Cost Era Is Ending

Kentucky's historical electricity advantage came from one source: abundant, cheap coal. For decades, utilities built coal-fired power plants right at the mine mouth, burning Appalachian and Illinois Basin coal to produce some of the cheapest electricity in the country. As recently as 2014, coal generated 94% of Kentucky's electricity. Three forces are now collapsing that advantage.

Force 1: Coal Plants Are Retiring

Around 5,800 megawatts of Kentucky coal capacity has been retired since 2014. Mill Creek Units 1 and 2 are being taken offline. Kentucky Power's Big Sandy plant closed in 2025. KU's Brown Unit 3 and LG&E's Ghent Unit 2 were originally slated for retirement but have been delayed to meet rising demand. By 2024, coal's share of Kentucky generation had dropped to about 67% — still the second-highest coal share of any state (behind only Texas), but a dramatic decline from a decade ago.

The problem is not that coal plants are being forced offline by environmental rules. It is that aging coal units have simply become expensive to operate. An Energy Innovation analysis found that continued reliance on aging Kentucky coal plants is no longer the least-cost option, and that shifting toward renewables and storage could save ratepayers roughly $2.6 billion through 2050. That is a striking finding in a state whose political leadership has historically championed coal as the cheapest source of power.

Force 2: New Natural Gas Plants

To replace retiring coal generation and meet growing demand, LG&E and KU are building two large new natural gas combined-cycle plants. In October 2025, the PSC approved the utilities' request to construct:

• Mill Creek 6 — a 645-megawatt natural gas combined-cycle unit in Louisville
• Brown 12 — a 645-megawatt natural gas combined-cycle unit in Mercer County
• Environmental upgrades for Ghent Unit 2

The combined capital cost is approximately $3 billion — down from LG&E/KU's original $3.7 billion request. The difference? The original proposal included a large battery storage system, which was cut from the final plan in a settlement with the Kentucky Attorney General. In its place, the utilities agreed to extend the life of a coal unit at the Mill Creek plant. Consumer advocates criticized the settlement for locking in more coal and fewer clean energy options, but it did trim the rate impact on customers.

These plants have to be paid for. The capital costs flow into rate base, which flows into the rates you pay.

Force 3: Data Centers

Kentucky is becoming a data center hotspot, and the ramp is steep. In January 2025, LG&E announced its first major data center customer: a 400-megawatt hyperscale campus being built by PowerHouse Data Centers (Virginia) and Poe Companies (Louisville) on 153 acres near the Rubbertown neighborhood in south Louisville. The first building, drawing 130 MW, is scheduled to come online in the fourth quarter of 2026. A new LG&E switch station is being built to serve it, targeted for completion in September 2026.

At full buildout, the campus will consume 400 MW — equivalent to powering about 400,000 homes, or by LG&E's estimate, about 280,000 residential customers. The Kentucky legislature sweetened the pot in 2024 with a 50-year tax exemption for data centers in Louisville and Jefferson County.

LG&E and KU have told regulators they expect 90% of their new economic development load by 2032 to come from data centers. To serve that demand, the utilities are building the 1,300+ MW of new generation described above. Consumer advocates and environmental groups warn that residential customers could end up subsidizing the infrastructure buildout. Data centers have dedicated tariffs that cover their direct service, but system-wide upgrades — new transmission, new substations, distribution improvements — typically get folded into base rates that all customers pay. Whether the new generation ends up raising or lowering residential rates depends entirely on how the fixed costs are allocated in future rate cases, and that fight is just beginning.

The Rubbertown location is also controversial for another reason. It is a predominantly Black neighborhood with a long history of industrial pollution, and residents have protested the project. In March 2026, the Louisville Metro Council approved the project despite community opposition.

This is the defining consumer story for Kentucky electricity in the late 2020s: will the data center boom raise or lower residential bills, and who decides?

Understanding Kentucky's Rate Structures

Knowing how Kentucky rate structures work gives you real opportunities to save.

Seasonal Rates

LG&E, KU, and most other Kentucky investor-owned utilities use a seasonal rate structure. Summer rates (typically May through September or June through September depending on the utility) are higher than non-summer rates. This reflects the fact that cooling load — running air conditioners during hot, humid Kentucky summers — drives most of the state's peak electricity demand.

The practical implication: cutting summer usage has an outsized impact on your annual bill. Every kWh you avoid in July is more valuable than a kWh avoided in February. Investing in efficient cooling, insulation, and shade is particularly worthwhile. Smart thermostats that precool the house before peak hours and raise the setpoint during the middle of the day are one of the highest-return efficiency upgrades you can make.

Time-of-Day Options

LG&E, KU, and Duke Energy Kentucky all offer voluntary residential time-of-day (TOD) rate options. On these plans, peak hours (typically weekday afternoons in summer) are billed at a higher rate, and off-peak hours (overnights, weekends) at a lower rate. If you can shift your laundry, dishwasher, EV charging, and water heating to off-peak hours, a TOD plan can meaningfully lower your average rate.

EV owners are the biggest winners on TOD plans. Overnight charging falls squarely in the cheapest off-peak window, and an EV can easily add 200-300 kWh per month to your bill. Getting that usage into the off-peak block is a significant savings opportunity.

What's On Your Kentucky Bill

A typical Kentucky electric bill includes several components beyond the energy charge:

• Energy charge (per kWh) — the largest component, priced seasonally
• Basic service charge (fixed monthly fee) — ~$14-15 depending on utility
• Environmental surcharge (ES) — covers pollution control costs at coal plants
• Fuel adjustment clause (FAC) — monthly pass-through of fuel cost fluctuations
• Local franchise fees — in applicable cities
• School tax — Jefferson County (Louisville) adds a school tax to bills

The environmental surcharge is worth flagging because it is directly tied to Kentucky's coal-heavy generation mix. As coal plants retire and are replaced with natural gas, the ES is expected to shrink over time, but transition costs from coal retirement will appear in other line items instead.

Solar Energy in Kentucky: Post-HB 227 Reality

Kentucky was once a reasonable solar state. Average payback periods for a residential solar system ran about nine years, and full 1-to-1 retail net metering meant that every excess kilowatt-hour you exported to the grid was credited at the same rate you paid when you imported power. That changed in 2019.

What HB 227 Did

House Bill 227, signed into law in 2019 and effective in 2020, ended Kentucky's full retail net metering for new solar customers. The bill directed the Kentucky PSC to set new "net metering tariffs" through individual utility rate cases, moving compensation from the retail rate (roughly 11-14 cents/kWh depending on utility) to avoided-cost or wholesale-based rates (typically 3-4 cents/kWh). Duke Energy Kentucky was the first to fully transition in November 2024 under what it calls "Net Metering II." LG&E, KU, and Kentucky Power have similar structures in place.

Customers with solar systems installed before their utility's transition date were grandfathered into full retail net metering for up to 25 years. But the grandfathered status does not transfer to a buyer if you sell your home — a punitive provision that significantly reduces the resale value of a solar-equipped house.

What Solar Looks Like in Kentucky Now

As of 2026, the average solar panel cost in Kentucky is approximately $2.63 to $2.70 per watt. A typical 7.5 kW system runs about $20,250 before incentives, while a larger 13.85 kW system runs around $36,393. The federal Investment Tax Credit for residential solar (which was 30%) has been winding down, so check current federal incentive status before you sign a contract.

Payback periods under current net metering rules run 12 to 16 years for most Kentucky homeowners, depending on utility and system size — meaningfully longer than the pre-HB 227 era. The economics work best when you consume most of your solar production yourself rather than exporting it. That means sizing your system carefully, running major appliances during daylight hours, and seriously considering battery storage to store excess production for evening use.

Battery storage has become much more attractive post-HB 227 because stored energy can be consumed later at full retail value, avoiding the low export compensation rate entirely. If you are shopping for solar, get quotes that include storage and compare the payback with and without batteries. For a broader look at panel selection and installer vetting, see our guide to choosing the best solar panels for your home.

Kentucky ranks near the bottom of all 50 states for solar and wind production. The state has not set a renewable portfolio standard, and recent legislation (SB 4 in 2023 and SB 349 in 2024) has actively made it harder for utilities to retire coal plants. For Kentuckians who want rooftop solar, the economics still work — but barely, and only with good planning.

Strategies to Lower Your Kentucky Electricity Bill

With rate increases arriving annually and coal plants leaving the grid, every efficiency improvement you make today becomes more valuable over time. Here are the highest-impact strategies for Kentucky homeowners.

1. Seal and Insulate First

Kentucky's older housing stock — especially in rural areas and older urban neighborhoods — is often poorly insulated and leaky. Air sealing (caulking, weatherstripping, sealing top plates and recessed lights) and attic insulation are the highest-return efficiency investments you can make. A home energy audit will identify the biggest leaks and prioritize fixes. If you qualify for the Weatherization Assistance Program, this work may be done for free.

2. Upgrade to a Heat Pump

Kentucky's moderate winter climate is ideal for heat pumps. Modern cold-climate heat pumps can handle almost any Kentucky winter, and in summer they provide efficient air conditioning. Replacing an old electric furnace or a gas furnace with a heat pump often lowers annual energy costs significantly, especially as electric rates remain below the national average. Federal tax credits for heat pump installation have been in place and may still apply — check current federal incentive status before purchasing.

3. Take Advantage of Seasonal Rates

Because Kentucky uses seasonal rates with higher summer pricing, cutting your summer kWh has an outsized impact. Set your AC to 78 degrees during occupied hours and let it float higher when away. Use a smart thermostat to precool before peak and reduce cooling during the hottest afternoon hours. Plant shade trees on the south and west sides of your home. Upgrade to ENERGY STAR windows if yours are old and leaky.

4. Switch to a Time-of-Day Plan

If you can shift usage — laundry, dishwasher, EV charging, water heating — to off-peak hours, a voluntary time-of-day rate plan will lower your average rate. EV owners benefit the most, but any household that can schedule heavy loads overnight or on weekends can save. Log into your utility's website to see TOD pricing and model potential savings.

5. Consider Solar with Storage

Despite HB 227, solar still works in Kentucky for homeowners who plan carefully. The key is high self-consumption. Get quotes for systems that include battery storage. Run the numbers using realistic usage profiles. Pay attention to the fact that grandfathered net metering does not transfer to a buyer — this affects the resale calculation.

6. Monitor Your Usage

You cannot manage what you do not measure. A home energy monitor shows you exactly where your electricity is going and often reveals surprises — a basement dehumidifier running constantly, a pool pump that could be scheduled, a water heater cycling too often. For a broader roadmap, our guide on how to cut your electric bill in half lays out a step-by-step plan.

7. Electrify Strategically

If you are planning to replace appliances anyway, consider electrification. Heat pump water heaters, induction cooktops, and electric dryers are all more efficient than their gas counterparts and save you the cost of a second utility bill. Our whole-home electrification guide walks through the process, especially for homeowners who want to phase changes over several years.

Low-Income Assistance Programs

Kentucky has several assistance programs for households struggling with electricity and heating costs. These are not only for the very poor — many working families qualify and do not realize it.

LIHEAP (Low-Income Home Energy Assistance Program)

LIHEAP is the federal program administered in Kentucky by the Cabinet for Health and Family Services through Community Action Kentucky (CAPKY) and 16 regional Community Action Agencies that cover all 120 counties. It serves about 150,000 Kentucky families per year through two main components.

Subsidy Component runs in November and December. It provides a one-time heating assistance payment to households at or below 130% of the Federal Poverty Guidelines. You do not need a disconnect notice or to be out of fuel to qualify for the subsidy.

Crisis Component runs January 6 through March 27 for the 2026 winter. It is designed for households facing imminent loss of heat — a disconnect notice, past-due bill, or (for propane/fuel oil/wood/coal customers) a fuel supply within four days of running out. Eligibility extends to households at or below 150% of Federal Poverty Guidelines.

The catch: federal LIHEAP funding has been uncertain in recent months. Following the 2025 federal government shutdown, annual LIHEAP disbursements were delayed, and program administrators have warned of potential shortfalls. If you need assistance, apply early and do not assume funding will be available late in the winter.

Weatherization Assistance Program (WAP)

Kentucky's Weatherization Assistance Program is administered by Kentucky Housing Corporation and funded through the federal Department of Energy. Unlike LIHEAP, which pays bills, WAP pays for permanent improvements that reduce your energy use — insulation, air sealing, HVAC tune-ups, duct sealing, window and door repair, and efficient appliances.

Income eligibility extends up to 200% of the federal poverty level. Households receiving SSI, TANF, LIHEAP, or SNAP are automatically eligible. The average investment per home is about $6,500, and weatherized homes typically see 15-25% lower energy bills on a permanent basis. If you qualify, this is one of the best programs to apply for because the savings continue for decades.

LG&E/KU WinterCare and HEAF

LG&E and KU operate two customer-funded assistance programs. WinterCare helps low-income LG&E and KU customers with heating bills during winter months. The Home Energy Assistance Fund (HEAF) provides broader bill payment assistance. Both are funded through voluntary contributions from other customers via an opt-in surcharge. Apply through your local Community Action Agency or call LG&E/KU customer service.

Other Resources

• Dial 2-1-1 for assistance referral anywhere in Kentucky
• Salvation Army Project Share — utility assistance
• St. Vincent de Paul — utility assistance
• Kentucky Power Neighbor to Neighbor — customer-funded bill assistance for Kentucky Power customers

Note that Kentucky does not have a hard winter disconnection moratorium. The PSC requires utilities to offer payment plans and gives medical necessity protections with documentation, but there is no blanket rule preventing disconnection in cold weather. If you are behind on your bill, contact your utility or your local Community Action Agency before you receive a disconnect notice. Options narrow quickly once shutoff is imminent.

Frequently Asked Questions

What is the average electricity rate in Kentucky?

As of 2025, the average residential electricity rate in Kentucky was about 13.14 cents per kWh, based on EIA data — roughly 21% below the national average of 16.73 cents. More recent real-bill data from EnergySage puts the early 2026 average closer to 12 cents per kWh. Kentucky remains one of the cheapest electricity states in the country, but rates have risen about 19% since 2020 and the gap with the national average is narrowing.

Why is my Kentucky electricity bill going up?

Three forces are driving Kentucky rate increases: aging coal plants are retiring and need to be replaced, new natural gas combined-cycle plants require billions in capital investment that flows into rates, and unprecedented data center demand (led by Louisville's 400 MW hyperscale project) is pushing utilities to build 1,300+ megawatts of new generation. In the last two years, LG&E, KU, Kentucky Power, and Duke Energy Kentucky have all won rate increases from the PSC. Depending on your utility, your bill has gone up somewhere between $5 and $13 per month in the last 12 months alone.

Can I choose my electricity provider in Kentucky?

No. Kentucky is a fully regulated electricity market. Residential customers are served by whichever utility holds the franchise for their area. The four major investor-owned utilities (LG&E, KU, Kentucky Power, Duke Energy Kentucky) and dozens of electric cooperatives serve distinct geographical territories set by the PSC. There is no community choice aggregation or retail competition for residential customers. Your options for reducing costs focus on managing usage, choosing the right rate plan where options exist, and using efficiency programs.

Is solar still worth it in Kentucky after HB 227?

Solar still works, but the economics have changed. Before HB 227, Kentucky solar customers got full 1-to-1 retail net metering and payback periods averaged around nine years. Now, new solar customers are compensated at avoided-cost or wholesale-based rates for excess exports (roughly 3-4 cents/kWh vs. retail rates of 12-14 cents). Payback periods have stretched to 12-16 years. The economics work best when you consume most of your own solar production, which makes battery storage increasingly attractive. Importantly, grandfathered net metering does not transfer to a home buyer if you sell your house.

Will Kentucky electricity rates keep going up?

Almost certainly, yes. LG&E and KU just committed to a stay-out period through August 2028, but that only limits general rate cases — it does not prevent fuel adjustment pass-throughs, environmental surcharges, or future rate cases after 2028. Kentucky Power's next increase is already scheduled for 2027. The new natural gas plants coming online for data center load, continued coal retirements, and ongoing distribution investment all point to continued upward pressure on rates. The question is not whether rates will rise, but how fast.

How much electricity does Kentucky still get from coal?

As of 2024, coal generated about 67% of Kentucky's electricity — still the second-highest coal share in the nation, behind only Texas. That is down from 94% in 2014. Natural gas has grown from 3% to about 26% over the same period. Wind, solar, and other renewables remain a small sliver of the mix — Kentucky ranks near the bottom of all states for renewable energy production. Two recent laws (SB 4 in 2023 and SB 349 in 2024) have slowed the pace of coal retirement.

What happens if I cannot pay my Kentucky electricity bill?

Kentucky does not have a hard winter disconnection moratorium, but several assistance programs are available. LIHEAP provides subsidy assistance in November-December and crisis assistance from January 6 through March 27. The Weatherization Assistance Program pays for permanent efficiency improvements that lower your bills long-term. LG&E/KU's WinterCare program helps with heating costs. Contact your local Community Action Agency or dial 2-1-1 as soon as you know you are having trouble — do not wait for a disconnect notice.

Are data centers really going to raise my bill?

Maybe. Data center customers sign long-term contracts that cover their direct power needs, but the broader infrastructure investments required to serve them — new generation, new transmission, new substations — can flow into base rates that all customers pay. Utilities argue that data centers will spread fixed costs over a larger sales base, potentially reducing residential rates. Environmental groups and consumer advocates argue residential customers will end up subsidizing the buildout. How this plays out depends on how the PSC allocates fixed costs in future rate cases. This is the defining consumer story for Kentucky electricity in 2026.

Your Kentucky Electricity Action Plan

Here is a concrete plan to take control of your electricity costs over the next year.

This week:

1. Pull up your most recent electric bill and identify your utility, your current rate schedule, your monthly kWh usage, and all the line items you are paying. If anything looks unfamiliar, our bill reading guide will help you decode it.
2. Log into your utility's website and review your usage history for the past 12 months. Identify your summer vs. winter peaks — Kentucky's seasonal rate structure means summer usage is more expensive per kWh.
3. Check whether a time-of-day rate plan would save you money given your usage patterns. LG&E, KU, and Duke Energy Kentucky all offer voluntary TOD pricing. If you have an EV, TOD is almost always worth running the numbers.

This month:

4. Schedule a home energy audit. Many Kentucky utilities offer free or discounted audits for residential customers.
5. Check your eligibility for the Weatherization Assistance Program through Kentucky Housing Corporation. If you qualify, the program provides free insulation, air sealing, and efficiency upgrades that permanently lower your bills.
6. Check LIHEAP eligibility through your local Community Action Agency or capky.org. Subsidy assistance runs November-December and Crisis assistance runs January 6 through March 27.
7. If you are considering solar, get at least three quotes. Make sure quotes include both system-only and system-plus-battery options, and confirm the installer's familiarity with your utility's post-HB 227 net metering tariff.

If you are struggling to pay your bill:

8. Dial 2-1-1 for statewide referral to local assistance agencies.
9. Contact your utility to ask about payment plan options and, if applicable, medical necessity protections.
10. Apply for LG&E/KU WinterCare or HEAF if you are a LG&E/KU customer, or Kentucky Power Neighbor to Neighbor if you are a Kentucky Power customer.

For the long term:

11. Budget for continued rate increases of 3-8% per year. Every efficiency improvement you make today compounds in value as rates climb.
12. Prioritize summer cooling efficiency — it has outsized impact under Kentucky's seasonal rate structure. Smart thermostats that precool and set back during peak hours are among the highest-return investments.
13. Consider a heat pump replacement if your HVAC system is more than 10 years old. Modern cold-climate heat pumps work well in Kentucky's winters and cut summer cooling costs substantially.
14. If you have available roof space and expect to stay in your home 15+ years, run a current solar quote. Payback is longer than it used to be, but rates are climbing fast and the math may still work — especially if you include battery storage and plan for high self-consumption.

Kentucky's low-cost electricity era is ending. Coal plants are retiring, new natural gas plants are coming online, data center demand is surging, and utilities are lining up billions in capital investment that will flow into rates. The good news is that Kentucky still enjoys below-average rates and has solid assistance programs for households in need. The Kentuckians who will pay the least over the next decade are the ones who start managing usage, claiming available incentives, and investing in efficiency improvements today.
