Home Backup Power Statistics 2026
A single reference page of the numbers that matter for US home backup power decisions in 2026: how often the grid actually fails, what batteries cost installed, and what changed after the federal tax credit ended. Every figure links to its primary source or to our methodology. Citation terms at the bottom.
Grid reliability: how long are homes actually without power?
- ~11 hours — average time a US electricity customer spent without power in 2024, the highest in a decade and nearly double the prior-decade average (EIA).
- 80% — share of 2024 outage hours attributable to major events, chiefly Hurricanes Beryl, Helene and Milton; major-event interruptions averaged ~9 hours vs ~4 hours/year in 2014–2023 (EIA).
- ~2 hours/year — the routine, non-major-event outage baseline for the average US customer (EIA).
- 1.5 interruptions — average number of outages per US customer in 2024 (EIA SAIFI).
- ~53 hours vs under 2 hours — the 2024 spread between the hardest-hit state (South Carolina) and the most reliable states (Arizona, the Dakotas, Massachusetts). Backup power is a regional decision: check your state's programs.
What backup power costs in 2026
- $700–$1,300 per kWh installed — the going range for residential battery storage as of late 2025/2026; a typical 13.5 kWh system runs ≈$15,000 before incentives (≈$1,100/kWh) (EnergySage, Solar.com).
- $9,000–$18,000 — typical whole-home battery project before incentives; industry forecasts point to ~8–12% year-over-year declines, putting late-2026 installs near $550–$850 per usable kWh.
- $0 — the federal residential clean energy credit available on new 2026 installs: the 25D credit ended December 31, 2025. What remains is state and utility money — see incentives by state and what the OBBBA actually changed.
- $500 / $1,000 / $2,500 — the three practical budget tiers for portable power stations covering hours-to-a-day outages; full picks in our portable guide.
- Two numbers decide the purchase — required inverter watts and storage kWh. Compute both for your home in 30 seconds with the battery size calculator.
How to read these numbers
The 2024 spike is a story about tail risk, not averages: the routine grid is fine (~2 h/year), but major-event years now stack 9+ hours on top, concentrated in storm-exposed states. That asymmetry is why sizing matters more than brand: a battery that covers your essential loads for the realistic outage in your state beats an oversized system bought on fear. With the federal credit gone, the 2026 economics hinge on (a) state/utility programs, (b) falling $/kWh, and (c) avoided losses — spoiled food, remote-work days, frozen pipes — which scale with local outage hours, not national averages.

FAQ
Why use 2024 outage data in 2026?
EIA publishes finalized reliability data with a lag; 2024 is the latest complete national dataset as of June 2026. We update this page when new annual data lands.
Do these costs include solar panels?
No — battery-only figures. Pairing with solar changes the math substantially (self-consumption under NEM 3.0-style rates); see battery without solar.
Battery or generator for long outages?
Multi-day outages in storm country still favor fuel or hybrid setups in many cases — the honest breakdown is in battery vs generator.
