How to read this guide
GridPermit collects Tennessee residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.
Permit timeline
7–30 days
Per the City's own page: residential permits typically receive approval within one week, with a standard target of 30 days for completed applications; commercial projects may require extended review.

Utility and generation supplier
Utility
Nashville Electric Service (NES)
NES is a municipally-owned utility and a local power company (distributor) for the Tennessee Valley Authority (TVA) — TVA generates and transmits power wholesale, while NES handles local distribution, billing, and customer-facing programs. Confirmed directly by the City's own permit page, which requires separate NES approval alongside the Metro Codes permit.
Sources & confidence
Generation supplier
Tennessee Valley Authority (TVA) (other)
TVA is the wholesale power generator/transmitter for the entire region; NES is the local distribution utility purchasing from TVA and reselling to Nashville-area customers. Some supporting official material could not be independently confirmed from the full source in GridPermit's latest review. Verify the current requirement with the authority before relying on it.
Sources & confidence
Interconnection
As a TVA local power company, NES does NOT offer traditional retail-rate net metering. Per NES's own 'NESolar Connect and NESolar Savings Guidelines' (effective October 2024), these two formal power-purchase programs are structured for LARGER systems, not typical single-family rooftop installations: NESolar Connect requires a minimum 200kW nameplate for solar facilities (35MW total program cap), and NESolar Savings covers systems up to 250kW DC with a minimum 50kWh average monthly excess generation (10MW total program cap) — both paid at fixed seasonal per-kWh rates (e.g., NESolar Savings: $0.03069/kWh summer, $0.03197/kWh winter) rather than retail-rate credit. Some supporting official material could not be independently confirmed from the full source in GridPermit's latest review. Verify the current requirement with the authority before relying on it.
