NES Municipal Utility — Nashville’s Own Solar Program, Not TVA
NES (Nashville Electric Service) Is a Municipal Utility With Its Own Solar Program. Metro Nashville Has a Consolidated Government — One Building Department. Tennessee Property Tax and Sales Tax Exemptions Apply.
NES (Nashville Electric Service) is a municipal utility that purchases power from TVA and distributes it to Davidson County customers with its own solar interconnection and net metering program. NES is not TVA — NES handles customer accounts, interconnection applications, and net metering for Nashville residential and commercial customers. Nashville's 1963 city-county consolidation means Metro Nashville-Davidson County Codes Administration handles permits for most Davidson County addresses — simpler than many metro markets. Tennessee's no-income-tax structure means no state solar tax credit, but property and sales tax exemptions apply.
NES — Municipal Utility · Own Interconnection · Not TVA
✅NES net metering: credits solar exports at retail rate for systems under 100 kW
✅NES interconnection application: separate from TVA, separate from investor-owned utilities
⚠️NES is the customer-facing utility for Nashville — TVA is the power source, not the interconnection contact
✅Submit NES interconnection simultaneously with Metro Nashville building permit
⚠️Some adjacent counties (Williamson, Rutherford) may have different utilities — confirm per address
Consolidated Metro Government · TN Tax Exemptions · NEC 2020
✅Metro Nashville-Davidson County Codes Admin handles permits for most Davidson County addresses
✅Consolidated government since 1963 — one department for City of Nashville and Davidson County
⚠️Brentwood, Franklin, Murfreesboro in surrounding counties have own departments — confirm AHJ
✅Tennessee property tax exemption for solar energy systems
✅Tennessee sales tax exemption on solar energy equipment and installation
⚠️ NES (Nashville Electric Service) and TVA are not the same entity. NES is the municipal utility that handles Nashville customer accounts, solar interconnection, and net metering. Installers from markets without municipal utilities sometimes try to contact TVA directly — TVA does not handle residential solar interconnection in Nashville. NES is the correct contact.
Why Nashville Installers Outsource
Contacting TVA Instead of NES. AHJ Mismatch for Williamson County. TN Tax Exemptions Not Communicated.
Contacting TVA for Nashville Residential Solar Interconnection
TVA is the power generator and transmission operator. NES is the municipal utility that handles Nashville customer accounts and solar interconnection. Installers unfamiliar with Tennessee's utility structure sometimes contact TVA directly for Nashville residential interconnection. TVA does not handle NES customer solar interconnection — NES does. We format every Nashville plan set for NES submission with the correct application documentation.
Routing a Brentwood or Franklin Address to Metro Nashville Codes Administration
Metro Nashville-Davidson County Codes Administration covers Davidson County. Brentwood and Franklin in Williamson County, and Murfreesboro in Rutherford County, have their own building departments. A plan set addressed to Metro Nashville for a Franklin address routes to the wrong jurisdiction. We confirm AHJ per address before building every Nashville metro plan set.
Tennessee Tax Exemptions Not Included in Customer Proposals
Tennessee has a property tax exemption for solar and a sales tax exemption on solar equipment. With no state income tax credit for solar, these exemptions are the primary state-level financial incentives. Nashville installers who don't highlight the property tax and sales tax exemptions are leaving a meaningful financial argument on the table in a state with no solar income tax credit.

Four Things That Define Solar in Nashville.
NES
Nashville Electric Service — Municipal Utility With Its Own Solar Program
NES (Nashville Electric Service) is a municipal utility serving Davidson County — purchasing power from TVA and distributing it to customers with its own rates, solar program, and interconnection process. NES net metering credits solar exports at the retail rate for systems under 100 kW. NES interconnection applications must be submitted to NES directly — not to TVA. NES is the customer-facing utility for all Nashville solar interconnection and net metering.
Metro AHJ
Consolidated Metro Government — One Building Department for Most of Davidson County
Nashville's 1963 city-county consolidation created Metro Nashville-Davidson County, a unified government covering most of Davidson County. Metro Nashville-Davidson County Codes Administration handles permits for both the City of Nashville and unincorporated Davidson County — a simpler AHJ structure than many large metros. Surrounding counties (Williamson, Rutherford, Sumner) maintain separate departments.
TN Exempt
Tennessee Tax Exemptions — Property Tax and Sales Tax on Solar Equipment
Tennessee exempts solar energy systems from property tax assessment, and Tennessee exempts solar energy equipment from the state sales tax. With no state income tax, Tennessee offers no solar income tax credit. These exemptions — particularly the sales tax exemption on commercial installations — are the primary state-level financial incentives for Nashville solar customers in 2026.
Fast Growth
Nashville — One of the Fastest-Growing US Cities — Large Solar Pipeline
Nashville has been one of the fastest-growing large US cities for over a decade, driven by healthcare, music, hospitality, and corporate relocations. Population growth and rising NES electricity rates create a strong and growing residential solar pipeline. Nashville's expanding commercial district, healthcare corridors, and growing suburban ring create meaningful commercial solar opportunities.
