Tennessee Valley Authority Solar Programs

The Tennessee Valley Authority serves about 10 million people across Tennessee, northern Alabama, Mississippi, Georgia, Kentucky, and Virginia — and its solar buyback rate is one of the most important numbers you need to understand before installing solar in TVA territory. Here’s what TVA’s solar programs actually offer in 2026, why the buyback structure pushes many homeowners toward battery storage, and what incentives remain available.

How TVA Solar Programs Work

TVA doesn’t provide electricity directly to most homeowners — it sells power wholesale to about 153 local power companies (LPCs) across the Tennessee Valley region. Your actual solar program terms depend on which LPC serves your home: Nashville Electric Service, Memphis Light Gas & Water, Huntsville Utilities, TVA’s direct-served industrial customers, and others all have slightly different net metering and buyback structures.

However, TVA sets the framework — and that framework is important to understand.

TVA’s Green Power Providers Program

TVA’s Green Power Providers (GPP) program is the primary mechanism for residential solar in TVA territory. Here’s how it works:

• Your solar system’s output is metered separately from your home’s consumption
• All electricity your panels produce is “sold” to TVA at the GPP rate
• You continue buying all your electricity consumption at your normal retail rate
• The GPP payment offsets your bill

The GPP rate has historically tracked below retail rates — often significantly below. This means TVA homeowners cannot simply “net meter” — self-consuming solar power in real time to avoid buying grid power. All production goes to TVA, and all consumption comes from TVA, at different rates.

In practice: If your retail rate is $0.12/kWh and the GPP buyback rate is $0.04–$0.06/kWh, you’re selling electricity for a fraction of what you’d pay to buy it. This fundamentally changes the solar economics compared to true net metering states.

The TVA Solar Buyback Rate in 2026

TVA periodically updates its GPP avoided cost rates. As of 2026, the residential GPP rate for distributed solar typically ranges from $0.038–$0.058/kWh depending on time of day and season — well below the retail rate most TVA-territory homeowners pay.

Contact your local power company for the exact current rate in your area. Nashville Electric Service, MLGW, and Huntsville Utilities each publish current buyback rates on their websites. The gap between retail and buyback varies by LPC.

Why Battery Storage Makes Sense in TVA Territory

Given TVA’s buyback structure, battery storage often makes more financial sense in TVA territory than in true net metering states — and this is the angle most solar installers in the region won’t lead with.

Here’s the logic: if your solar panels send power to the grid at $0.05/kWh but you buy it back at $0.12/kWh, you’re losing $0.07/kWh every time you export. A battery system captures that solar power instead, storing it for your use at night — saving $0.12/kWh instead of earning $0.05/kWh. The financial difference is significant.

Additionally, TVA territory experiences real weather events — winter ice storms in Tennessee and north Alabama, summer thunderstorm outages across the region. A battery provides backup power during these events with no additional complexity.

The EcoFlow DELTA Pro Ultra is a popular choice for TVA-territory homeowners adding battery storage to solar systems — it integrates with most inverter types and supports whole-home backup via a transfer switch. The Inergy Apex (code PZSGK8326) is another strong option, particularly for homeowners who want a modular, expandable system they can build over time.

Tennessee State Solar Incentives

TVA territory in Tennessee benefits from several state-level incentives:

• Tennessee does not have a state income tax credit for solar — Tennessee has no broad state income tax, so there’s no credit to claim
• Sales tax exemption — Tennessee exempts solar energy systems from the state’s 9.25% sales tax; on a $25,000 system, that’s $2,312 in savings
• Property tax exemption — Tennessee exempts the added value of a solar system from property taxes
• Federal ITC — expired December 31, 2025 for purchased residential systems; solar leases and PPAs still qualify via 48E credit through 2027

TVA Solar in Alabama, Mississippi, and Georgia

TVA also serves portions of northern Alabama (including Huntsville, Decatur, and Athens), a sliver of northern Mississippi, and a small section of northern Georgia. The same GPP program applies in these areas, administered through local power companies like Huntsville Utilities and Joe Wheeler Electric Membership Corporation.

Alabama and Mississippi have no state solar tax credits. Georgia homeowners in TVA territory can access Georgia’s property tax exemption but not a state income credit. The TVA GPP rate is the key variable in all these markets.

How to Go Solar in TVA Territory

1. Contact your LPC — find out the current GPP buyback rate and their interconnection process. Requirements vary between local utilities.
2. Get 3+ installer quotes — make sure installers are familiar with TVA’s GPP program and have experience filing the necessary paperwork with your specific LPC
3. Ask every installer about battery storage — given TVA’s buyback structure, the battery-first conversation is more important here than in net metering states
4. Understand the rate spread — calculate your payback period using the actual GPP buyback rate, not a generic net metering assumption
5. Size your system carefully — in TVA territory, oversizing your array exports more power at the low buyback rate; size to your consumption, not to maximize production

Frequently Asked Questions

Does TVA have a net metering program?

TVA does not offer traditional net metering. Instead, the Green Power Providers (GPP) program meters solar production separately from home consumption. All solar output is purchased by TVA at the GPP avoided cost rate (typically $0.038–$0.058/kWh), and homeowners buy all their electricity at the standard retail rate. The spread between these rates makes battery storage financially attractive in TVA territory.

Is solar worth it in TVA territory in 2026?

Yes, but the economics are different from net metering states. The low TVA buyback rate means solar savings come primarily from self-consumption — and battery storage maximizes that. With Tennessee’s sales tax exemption (saving 9.25% upfront) and property tax exemption, solar with battery storage often pencils out better than solar alone in TVA territory.

What is the TVA Green Power Providers rate in 2026?

The GPP avoided cost rate for residential solar in 2026 typically ranges from $0.038–$0.058/kWh depending on time of day and season. Contact your local power company (Nashville Electric Service, Huntsville Utilities, MLGW, etc.) for the exact current rate — it varies by LPC and is updated periodically by TVA.

Does TVA territory cover all of Tennessee?

TVA serves most of Tennessee plus portions of northern Alabama, northern Mississippi, northwestern Georgia, southeastern Kentucky, and southwestern Virginia. It sells power wholesale to about 153 local power companies; your utility is one of those LPCs. Contact TVA.com to confirm your area and find your local power company’s contact information.

Bottom Line

TVA’s solar program pays well below retail for exported solar power — which makes battery storage more important in TVA territory than nearly anywhere else in the South. Tennessee’s sales tax exemption offsets upfront costs meaningfully. With the federal ITC gone for purchased systems, the financial case for TVA-territory solar depends on honest math around the buyback rate spread and how much of your solar production you can self-consume. Get three quotes, ask about battery storage in every conversation, and confirm the exact current GPP rate with your local power company before finalizing your system size.
