Annual U.S. residential battery capacity under net metering; MW, 2016–2024.
United States residential net-metered battery systems are tracked annually from 2016 through 2024. Capacity is measured in megawatts for residential systems in the battery category. The series increased from 4.5 MW in 2016 to 2,271.9 MW in 2024. The 2024 level was 506.11 times the 2016 level, an increase of 2,267.4 MW.

Evidence: Supports all 9 annual U.S. observations for residential net-metered battery capacity.
EIA collected the category as batteries beginning in 2023; earlier entries in the same continuous series were labelled storage. The label transition does not alter the historical values reported in the series.
Annual values come from the U.S. EIA Electric Power Annual 2024 and use one consistent technology, sector and unit. The graphic uses eight anchor years for readability, while the page data retains every annual observation from 2016 through 2024. No missing years are interpolated.
All 9 observations use the same U.S. EIA annual release, one technology and sector definition, one unit and consecutive annual periods from 2016 through 2024.
