Is a home battery worth it in Tennessee?
Tennessee has no state net-metering mandate and no state battery rebate, so battery value comes mostly from backup during storm outages rather than bill arbitrage. The federal Section 25D purchase credit expired Dec 31 2025, so a 2026 cash buyer gets $0 federal.

What drives battery value here
Exposure to severe thunderstorms, tornadoes, and ice storms drives periodic multi-hour outages. Backup during storm outages is the main battery benefit, since export compensation is weak to none.
The federal picture in 2026
The federal residential purchase credit (Section 25D) expired on December 31, 2025, so a 2026 cash buyer gets nothing federal. The only surviving federal pathway is Section 48E, which a company claims on a lease or PPA. State and utility programs, where they exist, now do the heavy lifting.
