Tennessee interconnection rule
TVA role and no-net-metering confirmed from TVA FAQ (2021). TPUC jurisdiction statement (only Kingsport Power) not verified from TPUC source; Dispersed Power Production terms (size limits, rate) not retrieved; tva.com blocks direct fetch.
Tennessee Public Utility Commission (TPUC); Tennessee Valley Authority (TVA) as wholesale supplier/regulator of its local power companies
Interconnection rule– No general TPUC small-generator interconnection rule. TVA-area local power companies (munis/coops) use TVA program standards (Green Connect / Dispersed Power Production) and their own interconnection agreements. · source
Applies toNearly all of Tennessee is served by TVA-supplied municipal and cooperative local power companies (LPCs), whose retail rates and DG policies are governed by TVA wholesale contracts, not TPUC. TPUC regulates only investor-owned Kingsport Power (AEP Appalachian Power) in electricity; no TPUC interconnection rule was found.
Application formLPC-specific interconnection application/agreement; in participating LPCs the TVA Green Connect portal (www.greenconnect.com) or paper application is used for residential PV with TVA Quality Contractor Network (QCN) installer.
TimelinesGreen Connect: no time limit to install after application while program active; installation verification (1-2 hours) by Green Connect team with homeowner/installer/inspectors before commissioning (TVA Green Connect FAQ).
FeesLPC-specific ('pays all necessary fees' per TVA FAQ).
InsuranceTVA does not require liability insurance; many local power companies have their own liability insurance requirements (TVA Green Connect FAQ Q23).
Export compensationNone statewide – TVA Green Connect FAQ Q20-21
Net metering is not available in the TVA service area. Excess energy can be compensated via TVA Dispersed Power Production (with the local power company). Behind-the-meter PV allowed.
TVA local power companies (municipal utilities and cooperatives) set their own interconnection procedures and agreements; Green Connect participation is voluntary per LPC (residential PV, TVA QCN installer, TVA program standards, installation verification). Excess generation via TVA Dispersed Power Production.
