Is a home battery worth it in South Carolina?
Net-billing weakens export value, but real hurricane-outage risk and time-of-use rates plus possible Duke battery incentives make backup-focused batteries worth pricing out in 2026.
South Carolina at a glance
- Average residential rate
- 17 cents per kWh
- Net metering
- New residential customers are on Solar Choice / net-billing tariffs (adopted 2021), which credit exports below full retail with time-of-use and non-bypassable elements rather than 1-to-1.
- State battery incentive
- no direct state rebate; Duke Energy offers solar + battery incentive programs (such as PowerPair) in its SC territory, so confirm current availability with your utility
- Time-of-use plans
- Common and relevant here
What drives battery value here
Hit hardest in the 2024 hurricane season, with customers averaging roughly 53 hours without power, the most of any state that year. Storm backup is a genuine driver here given the severe 2024 outage hours; confirm any Duke battery program before assuming eligibility.
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.
