TVA Solar Overview
The Tennessee Valley Authority (TVA) is a government-owned corporation that provides wholesale electricity to local power companies (LPCs) across a seven-state region. Unlike traditional utilities where you deal directly with one company, TVA customers actually receive their electricity through 153 local distributors—each with potentially different solar policies.
Service area: TN, AL, MS, KY, GA, NC, VA
Customers: 10 million across 153 local utilities
Average rate: ~$0.11/kWh
Net metering: Limited—varies by local distributor
Solar rating: ★★☆ (Challenging) (Source: EIA Electric Power Monthly)
The complexity of TVA's structure means solar policies can vary significantly depending on which local power company serves your home. This guide covers general TVA policies, but you'll need to verify specifics with your local distributor.
Multi-State Service Area
TVA serves portions of seven states, each with different state-level solar policies that interact with TVA and local distributor rules:
| State | TVA Coverage | State Solar Policy | Notes |
|---|---|---|---|
| Tennessee | Nearly entire state | No state mandate | Follows TVA/LPC policies |
| Alabama | Northern region | Limited requirements | TVA distributors common |
| Mississippi | Northern region | No net metering mandate | Relies on TVA policy |
| Kentucky | Western region | State has net metering | May vary if TVA-served |
| Georgia | Small NW corner | Some programs available | Check local distributor |
| North Carolina | Small western area | Good state policies | TVA may override |
| Virginia | Small SW area | Improving policies | Limited TVA service |
TVA Net Metering Policy
Current TVA Solar Programs
TVA has historically been cautious about distributed solar. Current policies generally involve:
- Export compensation: Often at avoided cost rates, not retail
- System size limits: Typically capped based on usage
- Local variation: Each LPC may have different terms
- No state mandate: TVA isn't required to offer net metering
TVA Distributed Solar Program
| Feature | TVA Policy | Impact on Homeowners |
|---|---|---|
| Export credit rate | Avoided cost (~$0.03-0.05/kWh) | Lower than retail value |
| System size cap | Typically 10-50 kW residential | Adequate for most homes |
| Metering | Bi-directional required | Tracks production/consumption |
| Interconnection | Through local distributor | Process varies by LPC |
| Annual true-up | Varies by LPC | Check local policy |
TVA Electric Rates
Current Rate Structure
TVA provides wholesale power to local distributors, who add their own charges. The final rate you pay depends on your specific LPC:
| Component | Typical Range | Notes |
|---|---|---|
| TVA wholesale | ~$0.07-0.08/kWh | Base power cost |
| LPC distribution | ~$0.02-0.04/kWh | Local delivery charges |
| Fuel cost adjustment | Variable | Passes through fuel costs |
| Total retail | ~$0.10-0.12/kWh | What most customers pay |
Local Power Companies
Major TVA Distributors
Your local power company (LPC) handles billing, interconnection, and may have additional solar programs. Some of the larger TVA distributors include:
- Nashville Electric Service (NES): Serves Nashville metro
- Memphis Light, Gas & Water (MLGW): Memphis area
- Knoxville Utilities Board (KUB): Knoxville area
- Chattanooga EPB: Known for fiber internet + power
- Huntsville Utilities: Northern Alabama
- Bristol Tennessee Essential Services: Tri-Cities area
Finding Your Distributor
If you're not sure which LPC serves your area, TVA's website has a locator tool. Your electric bill will also show your local distributor's name and contact information.
Solar Economics with TVA
Typical System Economics
| Factor | TVA Territory | National Average |
|---|---|---|
| Electric rate | ~$0.11/kWh | ~$0.16/kWh |
| Sun hours/day | 4.5-5.0 | 4.5 |
| System cost (6kW) | $15,000-18,000 | $17,000-20,000 |
| Annual savings | $800-1,100 | $1,200-1,600 |
| Payback (purchase) | 14-18 years | 8-12 years |
Making Solar Work
- Maximize self-consumption: Use power as it's generated
- Consider batteries: Store excess vs. export at low rates
- Right-size system: Match daytime usage, not total usage
- PPA/Lease option: Still has 30% federal credit through 2027
- Future rate increases: Lock in solar now, avoid future hikes
2026 Federal Tax Credit
PPA/Lease: The Section 48E credit (30%) remains available through December 31, 2027. The solar company claims the credit and passes savings to you through lower payments. (Source: IRS guidelines and DSIRE Database)
What This Means for TVA Customers
With TVA's already challenging economics (lower rates, limited net metering), the loss of the federal credit for purchased systems makes the PPA/Lease option more attractive for many TVA customers:
| Option | Federal Credit | Best For |
|---|---|---|
| Cash purchase | None (expired) | Those who want ownership, long-term |
| Solar loan | None (expired) | Want ownership without upfront cost |
| PPA/Lease | 30% (through 2027) | Lower payments, no credit needed |
Tips for TVA Customers
Do This:
- Contact your LPC first: Get their specific solar policy in writing
- Ask about export rates: Know exactly what you'll be paid
- Calculate realistic payback: Use actual export rates, not retail
- Consider PPA/Lease: Benefits from remaining federal credit
- Size for self-consumption: Exports have low value
- Get multiple quotes: Costs vary significantly in TVA territory
Watch Out For:
- Assuming retail net metering: TVA doesn't offer it
- National installers unfamiliar with TVA: They may not understand local policies
- Oversized systems: Excess exports have very low value
- Ignoring LPC differences: Each distributor has different rules
- Expecting federal credit for purchase: 25D expired in 2025
Frequently Asked Questions
Does TVA have net metering?
TVA offers limited distributed solar programs, but not traditional 1:1 net metering. Export compensation is typically at avoided cost rates (~$0.03-0.05/kWh), not retail rates. Specific terms depend on your local power company.
What states does TVA serve?
TVA serves portions of Tennessee (nearly all), Alabama (north), Mississippi (north), Kentucky (west), Georgia (small NW corner), North Carolina (small western area), and Virginia (small SW area).
Is solar worth it with TVA?
Solar can work with TVA, but payback periods are longer than many areas due to lower rates and limited net metering. Focus on self-consumption, consider batteries, and explore PPA/Lease options that still benefit from federal credits.
Who is my local power company?
Check your electric bill for your local distributor's name, or use TVA's website to find your local power company by address. You'll deal with them for interconnection and billing, not TVA directly.
Can I get the federal tax credit with TVA?
For purchased systems, the 30% federal credit (Section 25D) expired December 31, 2025. For PPA/Lease agreements, the Section 48E credit (30%) remains available through 2027—the solar company claims it and passes savings to you.
What's the typical payback period in TVA territory?
For purchased systems without federal credit, expect 14-18 years payback due to lower electric rates (~$0.11/kWh) and limited net metering. PPA/Lease options can provide immediate savings with no payback period to wait for.
