Tennessee Electricity Rates: TVA Explained

Tennessee is not like other states when it comes to electricity. You cannot shop for a provider. You cannot switch to a cheaper plan. Every kilowatt-hour that flows into your home comes from the same source: the Tennessee Valley Authority, a federal corporation created by Congress in 1933. TVA generates the power, 153 local companies deliver it, and you pay whatever rate they set. There is no alternative.

The good news is that the system actually works reasonably well on price. Tennessee's average residential rate of roughly 12 to 14 cents per kWh is 23 to 39% below the national average, depending on which benchmark you use. The bad news is that rates have been climbing fast — TVA approved back-to-back base rate increases totaling about 10% over the past two years — and Tennesseans tend to use more electricity than the national average thanks to hot, humid summers and cold winters. The result: average monthly bills of $133 to $177, which can land right at or even above the national average despite those lower per-kWh rates.

This guide will explain exactly how Tennessee's unique electricity system works, what you're paying and why, and what you can do to spend less.

The Tennessee Valley Authority: A Federal Power Company

TVA is unlike any other electricity provider in the country. It is not a private utility. It is not a state agency. It is a federally owned corporation, created during the New Deal to bring electricity, flood control, and economic development to one of the poorest regions in America.

Today, TVA is the largest government-owned electricity provider in the United States. It operates across an 80,000-square-mile service area spanning parts of seven states — Tennessee, Alabama, Mississippi, Kentucky, Georgia, North Carolina, and Virginia — and serves approximately 10 million people through those 153 local power companies.

TVA owns and operates roughly 32 gigawatts of generating capacity. Its power comes from a diverse mix of sources:

Source	Share of Capacity	Notes
Natural gas	39%	Largest source and growing
Nuclear	26% capacity / ~40% generation	Largest carbon-free source
Coal	18%	Scheduled for retirement, though timeline is now uncertain
Hydroelectric	16%	Original TVA resource from the dam-building era
Solar	Less than 1%	Growing rapidly through the Green Invest program

Nuclear deserves special attention. TVA's seven reactors across three plants — Browns Ferry in Alabama, Sequoyah near Chattanooga, and Watts Bar in Spring City — generate about 40% of TVA's actual electricity output. That is a higher share than the capacity numbers suggest because nuclear plants run near full output around the clock. This nuclear fleet is the backbone of Tennessee's grid reliability and its largest source of carbon-free power.

TVA is self-funded through power sales. It receives no federal appropriations for its electricity operations. Instead of paying taxes, TVA makes payments in lieu of taxes (PILOT) to states and counties — over $500 million annually. This means TVA operates somewhat like a business, but one where the "customers" have no choice and the board answers to the federal government rather than shareholders or a state utility commission.

How the Market Works: 153 Companies, Zero Choice

Understanding Tennessee's electricity structure is essential to understanding your bill. Here is how the system works:

TVA generates and transmits electricity across its high-voltage transmission network
Local Power Companies (LPCs) buy wholesale power from TVA and distribute it to homes and businesses through local poles and wires
You pay your LPC, which bundles TVA's wholesale costs with the LPC's own distribution charges

You cannot choose your LPC — it is determined by where you live. And your LPC cannot buy power from anyone other than TVA. These exclusive supply contracts lock both the distributor and the consumer into a single-source arrangement.

There are 153 LPCs across the TVA service territory. They include municipal utilities (like Nashville Electric Service), electric cooperatives (like Middle Tennessee Electric), and utility districts. Despite the variety of organizational structures, they all buy from the same wholesaler.

Here is the critical difference from most other states: there is no state public utility commission regulating TVA's rates. TVA's board of directors sets wholesale rates, and there is no state-level body that can override them. LPC boards — often appointed by local government — set the retail rate structures that determine exactly how much you pay per kilowatt-hour, but the TVA wholesale cost makes up 80% or more of every dollar on your bill.

This means that when TVA raises its wholesale rate, your bill goes up, and neither you nor your local utility has any meaningful leverage to prevent it.

If you want to understand exactly how all these charges show up on your monthly statement, our guide on how to read your electric bill and spot overcharges breaks down each line item.

What Tennesseans Actually Pay

Let's get specific about the numbers. In 2026, the average residential electricity rate in Tennessee falls between 12 and 14 cents per kWh. That compares favorably to the national average, which ranges from about 16.73 to 20 cents per kWh depending on the source and methodology.

Monthly bills tell a different story. Because Tennessee households use more electricity than the national average — driven by air conditioning in summer and electric heating in winter — average monthly bills range from $133 to $177. Some estimates put the figure at $155 per month. The national average sits at $147 to $157. So despite paying less per kilowatt-hour, many Tennessee households end up spending just as much or more on their monthly bill.

Rates have been climbing. Between 2021 and 2025, Tennessee electricity costs increased approximately 29%. The most significant recent jumps came from TVA itself:

FY 2024: 4.5% base rate increase
FY 2025: 5.25% base rate increase (effective October 2024)

That is roughly 10% in two years. For the average residential customer, the FY 2025 increase alone added about $4.35 per month to their base bill. Across TVA's entire customer base, the increase generated nearly $500 million in additional annual revenue.

These rate increases are funding grid modernization, new generation capacity, and infrastructure to meet surging demand from data centers moving into the Tennessee Valley.

Comparing Tennessee's Major Local Power Companies

While all LPCs buy from TVA, they are not identical. Distribution charges, customer fees, and service quality vary. Here are the four largest:

LPC	Service Area	Customers	Avg. Rate (cents/kWh)	Est. Monthly Bill (1,000 kWh)
Nashville Electric Service (NES)	Nashville/Davidson County	~430,000	10.22 (energy only)	~$154
Memphis Light, Gas and Water (MLGW)	Memphis/Shelby County	~400,000	Varies (multiple rate increases)	Varies
Knoxville Utilities Board (KUB)	Knoxville/Knox County	~219,000	10.86-12.86	Varies
EPB (Chattanooga)	Chattanooga/Hamilton County	~180,000	12.00-12.53	~$143

Nashville Electric Service (NES) is one of the largest LPCs and serves the fast-growing Nashville metro area. NES charges an energy rate of 10.216 cents per kWh, but also applies tiered customer charges: $14.06 per month for usage up to 500 kWh, $18.96 for 500 to 2,000 kWh, and $26.96 for higher usage. Including all charges, a household using 1,000 kWh can expect a bill around $154. NES passed along a 2.9% rate increase in October 2024, driven by TVA's wholesale hike.

Memphis Light, Gas and Water (MLGW) is the largest three-service municipal utility in the United States, providing electric, gas, and water to the Memphis area. MLGW implemented a 4% electricity rate increase in early 2025 — adding about $5 per month for the average household — as the second of three planned annual increases. MLGW is also at the center of the most significant challenge to TVA's monopoly in decades (more on that below).

Knoxville Utilities Board (KUB) serves roughly 219,000 customers in the Knoxville area. More than 80 cents of every dollar KUB collects goes directly to purchasing power from TVA, leaving relatively little room for KUB to influence pricing. KUB applies periodic purchased power adjustments that fluctuate — the January 2026 adjustment was 1.363 cents per kWh.

EPB (Chattanooga) has earned a national reputation that extends well beyond electricity. At around 12 to 12.53 cents per kWh, EPB's rates are competitive with other Tennessee LPCs. But what sets EPB apart is its fiber-optic smart grid, which has reduced power outages by 60% and made Chattanooga famous as "Gig City." We will cover EPB's smart grid in more detail later in this guide.

Other notable LPCs include Middle Tennessee Electric (MTE), one of the largest electric cooperatives in the country, serving Murfreesboro and surrounding counties, and Volunteer Energy Cooperative in East Tennessee.

The Memphis Question: Could MLGW Leave TVA?

The most dramatic storyline in Tennessee electricity is happening in Memphis. MLGW is TVA's single largest customer, and Memphis has been actively exploring whether it could do better on its own.

The Brattle Group, an independent economic consulting firm, studied the question and concluded that Memphis could save $240 to $333 million per year by leaving TVA and sourcing power independently through the MISO wholesale market (Midcontinent Independent System Operator). Those savings would come from access to competitive wholesale pricing and cheaper renewable energy.

TVA took the threat seriously and offered over $500 million in additional incentives to keep Memphis, including a proposed 20-year "long-term partnership agreement" with a 3.1% wholesale bill credit. Of TVA's 153 local power companies, 148 have signed these 20-year contracts.

MLGW is one of only five that have not.

In December 2022, the MLGW Board unanimously rejected TVA's 20-year offer, calling it too long of a commitment. Memphis remains on a 5-year rolling contract instead. However, in May 2023, MLGW's CEO announced the utility would stick with TVA for now under the existing arrangement.

The situation is complicated by TVA's contract terms. Under the current agreement, MLGW cannot generate its own electricity — not even rooftop solar. The exclusive supply contract essentially prevents Memphis from pursuing any independent power generation while remaining a TVA customer. MLGW has managed to install a first-ever battery storage system, but larger moves are blocked.

If Memphis eventually left TVA, it would be the largest defection in TVA history and could encourage other LPCs to reconsider their own arrangements. Community advocates in Memphis continue pushing for alternatives, citing both cost savings and the opportunity to pursue more renewable energy. The issue remains politically active and worth watching.

Understanding Your Tennessee Electric Bill

Your monthly bill is built from several layers. Knowing what each layer does helps you figure out where your money is going and where you might find savings.

TVA wholesale charges (about 80% of your bill):

Base demand and energy charges — the core cost of power
Fuel Cost Adjustment (FCA) — a monthly line item that fluctuates with natural gas and coal prices
Grid Access Charge — covers transmission infrastructure

LPC distribution charges (about 20% of your bill):

Customer charge — a flat monthly fee you pay regardless of usage ($14 to $27 depending on your LPC and consumption tier)
Energy charge — a per-kWh rate for the distribution service
Local infrastructure, metering, and customer service costs

The Fuel Cost Adjustment deserves special attention because it can swing your bill noticeably from month to month. In May 2025, the residential FCA was 2.774 cents per kWh. By December 2025, it had dropped to 2.093 cents per kWh. Since natural gas is TVA's largest generation source at 39% of capacity, your bill is directly tied to the natural gas market.

TVA also uses seasonal rate periods:

Summer (June through September): Highest rates
Winter (December through March): Moderate rates
Transition (April-May, October-November): Lowest rates

If you have flexibility in when you run energy-intensive tasks — laundry, dishwashers, charging an EV — the transition months are the cheapest time to use electricity. Some LPCs, including KUB and MLGW, also offer time-of-use rate schedules where off-peak hours (nights and weekends) are cheaper than peak afternoon hours.

Solar in Tennessee: The Math Is Tough

If you're considering rooftop solar in Tennessee, you need to understand one critical fact: Tennessee does not offer net metering.

In states with net metering, excess solar power you send to the grid earns you a credit at or near the full retail rate — meaning every kilowatt-hour your panels produce is worth 12 to 14 cents whether you use it yourself or export it. Tennessee does not work that way.

Under TVA's Green Power Providers program, your solar generation and consumption are measured separately with dual meters. The electricity you consume directly from your panels saves you the full retail rate. But any excess you export to the grid earns only the avoided cost rate — roughly 2 cents per kWh. That is a fraction of the 12 to 14 cents you pay to buy electricity from the grid.

This means the financial case for solar in Tennessee depends almost entirely on how much of your solar production you can consume yourself, rather than export. Payback periods in Tennessee typically run 12 to 18 years or more, compared to 6 to 10 years in states with full retail net metering.

That said, solar is not worthless in Tennessee. The federal 30% Investment Tax Credit still applies, which significantly reduces the upfront cost. And every kilowatt-hour you use directly from your panels does avoid the full retail rate. If you pair solar with a home battery to store excess production for evening use (instead of exporting at 2 cents), you can improve the economics meaningfully.

Tennessee has no state solar tax credit, no state renewable portfolio standard, and no sales tax exemption on solar equipment. It is, frankly, one of the least solar-friendly states in the country due to TVA's monopoly structure and the absence of net metering.

For large commercial customers, the picture is different. TVA's Green Invest program has attracted nearly $3 billion in solar investment from companies like Google, Facebook, General Motors, Vanderbilt University, and even Jack Daniel's. TVA aspires to add 10 GW of solar by 2035 and currently has about 4 GW operating or committed. But these large-scale programs do not directly help residential customers with their bills.

TVA EnergyRight Rebates: Free Money for Upgrades

While Tennessee lacks some incentives available in other states, TVA's EnergyRight program offers meaningful rebates for energy efficiency upgrades. These are available through participating LPCs across the service territory.

Upgrade	Rebate Amount	Requirements
Air source heat pump	$800-$1,500	SEER2 14.2+ required
High-efficiency central air	$700	Must meet efficiency thresholds
Heat pump water heater	$500-$1,300	Amount varies by LPC
Attic, wall, or floor insulation	Up to $700 per home	Installed by TVA-approved contractor
Duct sealing and repair	$300	Sealing, repairing, insulating ductwork
Air sealing (home envelope)	$300	Reduces drafts and energy loss
HVAC tune-up	$50	Electric heating systems in winter
Energy-efficient windows	$15 per window	Replacement windows

All rebates require work by a contractor in TVA's Quality Contractor Network. The contractor handles the rebate paperwork and submits it to EnergyRight for processing. You can stack multiple rebates on a single home — for example, combining a heat pump installation with insulation and duct sealing.

On top of TVA rebates, federal tax credits under the Inflation Reduction Act apply in Tennessee:

30% credit (up to $2,000) for qualifying heat pumps — see our guide on the best heat pumps for home
30% credit for solar panel installations
Up to $1,200 per year for energy efficiency improvements (insulation, windows, doors)
$150 credit for a professional home energy audit

A heat pump upgrade is one of the highest-impact investments for Tennessee homeowners. If you're heating with electric resistance or an aging HVAC system, a modern heat pump can cut heating costs by 30 to 50%. Our guides on the best heat pumps and best heat pump water heaters cover what to look for.

Low-Income Assistance and Weatherization Programs

Tennessee has several programs that help households struggling with electricity costs.

LIHEAP (Low-Income Home Energy Assistance Program) provides direct bill assistance of $174 to $750 per household, depending on energy burden. Eligibility requires household income at or below 60% of the state median income. The 2025-2026 application period runs from November 1, 2025 through September 30, 2026. Payments go directly to your utility company. Crisis applications — households facing shutoff — receive priority. Applications are submitted through the SmartSimple online system, administered by the Tennessee Housing Development Agency (THDA) through local agencies.

A note of caution: federal funding uncertainty has affected LIHEAP in 2026. Some agencies have placed eligible applicants on waiting lists due to delayed federal appropriations.

TVA EnergyRight Home Uplift is one of the most generous weatherization programs in the country. Qualifying households — those at or below 80% of area median income — receive $9,000 to $12,000 in free home weatherization upgrades. That includes HVAC replacement, insulation, air sealing, and duct repair, all at no cost to the homeowner. The program operates through participating LPCs including NES, MLGW, KUB, and EPB. Tennessee's Department of Environment and Conservation has provided grants of $1.25 million each to these four LPCs to extend the program's reach.

Tennessee Weatherization Assistance Program (WAP) is a separate federal program administered by THDA that provides weatherization services across all 95 Tennessee counties. It prioritizes people with disabilities, older adults, and families with limited incomes.

If you qualify for any of these programs, apply. The Home Uplift program in particular represents thousands of dollars in upgrades that will permanently lower your monthly bills.

Grid Reliability: Nuclear Backbone and EPB's Smart Grid

Tennessee's grid reliability story has two standout elements: TVA's nuclear fleet and Chattanooga's EPB smart grid.

TVA's nuclear plants provide stable, weather-independent baseload power that runs around the clock. The fleet's three stations represent roughly 8,400 MW of capacity:

Plant	Location	Reactors	Capacity	License
Browns Ferry	Athens, AL	3	~3,800 MW	Extended to mid-2050s
Sequoyah	Soddy-Daisy, TN	2	~2,300 MW	Renewal pending (early 2040s)
Watts Bar	Spring City, TN	2	~2,300 MW	Unit 1: 2035, Unit 2: 2055

Browns Ferry is the third-largest nuclear station in the United States. Its license was extended by 20 years in 2025, keeping all three units operational into the 2050s. Watts Bar Unit 2, completed in 2016, was the last nuclear unit built in the US for over two decades.

TVA is also investing approximately $200 million in small modular reactor (SMR) technology at the Clinch River site in Oak Ridge, with a construction permit application already submitted to the Nuclear Regulatory Commission. If successful, this could add a new class of nuclear generation to the Tennessee Valley.

EPB's fiber-optic smart grid in Chattanooga is arguably the most impressive municipal utility infrastructure in the country. EPB built a 9,000-mile community-wide 100% fiber optic network that serves double duty: it delivers gigabit internet (Chattanooga was the first city in the US to offer 1 Gbit/s service in 2010, and now offers 10 Gbit/s) and it powers a smart electric grid with over 1,400 automated switches.

Those switches can detect and reroute power around damaged infrastructure automatically, without waiting for a repair crew. The result: power outages have been reduced by an average of 60%, saving customers approximately 19 million outage minutes per year. An independent study valued the community benefits of EPB's fiber network at $2.69 billion over its first decade, including 9,516 jobs and $244 million in new business ventures. EPB was the first major power distribution system to earn PEER certification in 2016.

On the less encouraging side, TVA's coal plant transition has hit turbulence. The Cumberland and Kingston coal plants were originally scheduled for retirement by the late 2020s, but TVA's board voted in February 2025 to delay those retirements. TVA's CEO has indicated the utility is considering keeping coal plants running beyond 2035 — reversing the original retirement timeline. Meanwhile, TVA brought 530 MW of new natural gas capacity online at Johnsonville in 2025 and is evaluating over 6,200 MW of additional resources in its development pipeline.

Frequently Asked Questions

Why cannot I choose my electricity provider in Tennessee?

Tennessee is served by TVA, a federal corporation that has exclusive supply contracts with 153 local power companies. Unlike deregulated states such as Texas or Ohio, there is no retail competition. Your local power company — whether that is NES, MLGW, KUB, EPB, or a rural cooperative — is your only option. You cannot switch to a different provider.

Is Tennessee electricity actually cheap?

Per kilowatt-hour, yes. At roughly 12 to 14 cents per kWh, Tennessee rates are 23 to 39% below the national average. However, Tennessee households tend to use more electricity than the national average due to hot, humid summers and cold winters. Higher consumption can push monthly bills to $155 or more, which is close to or above the national average. Low rates do not automatically mean low bills.

Why has my electric bill gone up so much recently?

TVA approved back-to-back base rate increases: 4.5% in FY 2024 and 5.25% in FY 2025, totaling roughly 10% over two years. On top of that, the monthly Fuel Cost Adjustment fluctuates with natural gas prices and can add 2 to 3 cents per kWh to your bill. Your LPC may have also increased its own distribution charges. The combination of all three factors has pushed bills noticeably higher.

Is rooftop solar worth it in Tennessee?

It depends on your situation. Tennessee has no net metering, so excess solar you export to the grid earns only about 2 cents per kWh — far below the 12 to 14 cent retail rate. Solar still saves money on electricity you consume directly from your panels (avoiding the retail rate), and the federal 30% tax credit applies. But payback periods are typically 12 to 18 years, compared to 6 to 10 years in states with full net metering. If you can use most of your solar production yourself, the investment may still make sense.

What is the TVA Fuel Cost Adjustment on my bill?

The Fuel Cost Adjustment (FCA) is a monthly line item that reflects TVA's actual cost of fuel — primarily natural gas and coal — to generate electricity. It fluctuates every month based on fuel market prices. In recent months, the residential FCA has ranged from about 2.1 to 2.8 cents per kWh. When natural gas prices spike, so does the FCA, and your bill rises even if you have not changed your usage.

Could Memphis actually leave TVA?

Technically yes, but it is complicated. MLGW, Memphis's utility, rejected TVA's 20-year contract in 2022. An independent study by the Brattle Group found Memphis could save $240 to $333 million per year by sourcing power independently through the MISO wholesale market. However, MLGW's CEO indicated the utility will stick with TVA for now. The current exclusive supply contract prevents MLGW from generating its own electricity — even rooftop solar. The issue remains politically active in Memphis and is worth watching.

What rebates and tax credits are available for Tennessee homeowners?

TVA EnergyRight offers rebates for heat pumps ($800-$1,500), heat pump water heaters ($500-$1,300), insulation (up to $700), duct sealing ($300), air sealing ($300), and HVAC tune-ups ($50). Federal tax credits include 30% for solar installations, up to $2,000 for qualifying heat pumps, and up to $1,200 per year for insulation, windows, and doors. These can be stacked — a single project can qualify for both TVA rebates and federal credits.

What help is available if I cannot afford my electric bill?

LIHEAP provides $174 to $750 in direct bill assistance for qualifying households with income at or below 60% of the state median. TVA's Home Uplift program provides $9,000 to $12,000 in free weatherization upgrades for homes below 80% of area median income. Tennessee's Weatherization Assistance Program covers all 95 counties and prioritizes seniors, people with disabilities, and low-income families. Contact your local community action agency or visit the THDA website to apply.

Your Tennessee Energy Action Plan

You cannot switch providers, but you can still take meaningful steps to lower your electricity costs. Here is a concrete plan:

This week:

Pull your last 12 months of bills. Log into your LPC's online portal and note your monthly kWh usage and total charges. Identify your highest and lowest months. Understanding your usage pattern is the foundation for everything else. Our guide on how to read your electric bill and spot overcharges will help you decode each line item.
Check for billing errors. Look for charges that do not match your LPC's published rate schedule. Verify your meter readings look consistent with your actual usage. Billing errors are more common than most people realize.
Install a smart thermostat. Heating and cooling typically account for 40 to 50% of a Tennessee household's electricity bill. A smart thermostat can cut that cost by 10 to 15% — saving $15 to $25 per month — by automatically adjusting temperatures when you are asleep or away. Some TVA EnergyRight programs offer rebates on smart thermostats as well.

This month:

Do a DIY energy audit. Walk through your home looking for air leaks around windows, doors, and electrical outlets. Check your attic insulation depth. Feel for drafts around ductwork. Our DIY home energy audit guide walks you through the process step by step.
Check your insulation. Tennessee homes need adequate attic insulation to handle both summer heat and winter cold. If your attic has less than 10 to 14 inches of insulation, you are likely losing significant energy. Our attic insulation guide covers materials, costs, and what to expect. TVA EnergyRight offers up to $700 in rebates for insulation upgrades.
Consider a home energy monitor. A real-time energy monitor shows you exactly which appliances and systems are consuming the most electricity. Many Tennessee homeowners are surprised to find that an aging water heater, a second refrigerator, or phantom loads from electronics are costing them $20 to $40 per month.

This quarter:

Evaluate your HVAC system. If your heating and cooling system is more than 12 to 15 years old, a modern heat pump can cut energy use dramatically. TVA EnergyRight rebates of $800 to $1,500 combined with federal tax credits of up to $2,000 can offset a significant portion of the cost. See our best heat pumps guide for what to look for.
Look into your water heater. If you have a standard electric resistance water heater, a heat pump water heater uses about 60 to 70% less electricity. TVA rebates of $500 to $1,300 plus federal tax credits make this one of the best efficiency investments available.
Check if you qualify for assistance. If your household income is below 80% of the area median, apply for TVA's Home Uplift program — $9,000 to $12,000 in free weatherization is life-changing for your energy bills. If you are below 60% of the state median income and struggling to pay your bill, apply for LIHEAP through your local community action agency.
Shift usage to off-peak and transition seasons. Run high-energy appliances during transition months (April-May, October-November) when TVA rates are lowest. If your LPC offers time-of-use rates, shift laundry, dishwashing, and EV charging to nights and weekends. Even without TOU rates, being mindful of summer peak demand (June through September) and reducing usage during those months saves real money.

Tennessee's electricity system does not give you the power to choose your provider. But it does give you the power to control how much electricity you use, when you use it, and how efficiently your home handles the energy it consumes. The difference between a passive approach and an active one can easily be $500 to $1,000 per year — real money that stays in your pocket instead of flowing to TVA.
