Who submits

Export compensation

Avoided cost – Behind-the-meter self-consumption, or TVA Dispersed Power Production (excess sale)
No net metering. TVA (wholesale supplier) role: Tennessee has no state net metering mandate and the TN PUC does not regulate TVA local power companies (LPCs); the LPC sets its own interconnection rules under its TVA wholesale contract. For export compensation from TVA, the customer first establishes an interconnection agreement with the LPC and can then register in TVA's Dispersed Power Production (DPP) program to sell all or excess generation to TVA at avoided cost (time-of-day rates); metering at customer expense to TVA specs. Some LPCs (under TVA Long-Term Partnership flexibility) instead buy excess generation in their own programs.
