Small and DIY interconnection requirements
TVA isn't your utility: it's the federal wholesale authority behind roughly 153 local power companies, and your interconnection agreement is always with your LPC, under the LPC's own rules. TVA sets the framework on top. documented
No net metering exists anywhere in TVA territory, their own FAQ states it flatly. Self-consumption is the entire game here. documented
Exports can still pay through Dispersed Power Production: sell excess or all generation to TVA at avoided cost, paid monthly by ACH, enrolled via the TVA Green Hub. An executed interconnection agreement with your LPC comes first, and systems 250 kW or under skip TVA transmission screening. documented
Green Connect, the residential on-ramp, requires a TVA Quality Contractor Network installer, so pure DIY takes the plain LPC-interconnection route instead. And mind the fine print: without DPP enrollment, the agreement says you will not be reimbursed for power that flows to the grid. documented
