Global Battery Storage Additions for 2025 Split Between 106 GW and 112 GW Across Trackers

Energy · 2026-07-31 06:08

IEA-sourced figures put 2025 global battery/energy storage capacity additions at a record 108 GW, roughly 40% above 2024. Wood Mackenzie's independent tally lands close behind at 106 GW (+43%), while BloombergNEF reports a higher 112 GW / 307 GWh (+48%) after excluding pumped hydro. InfoLink Consulting measures the year differently in GWh terms -- 275.3 GWh, a steeper 61.3% year-over-year increase -- diverging from the other trackers on both scale and growth-rate framing. All four agree 2025 was a record year; they disagree on by how much and on which metric best captures it.

Findings

  • IEA data (via SolarQuarter/Energy Storage News, June 2026) puts 2025 global battery storage additions at 108 GW, a ~40% increase over 2024, with utility-scale projects accounting for roughly 87 GW (80%) of the total.
  • Wood Mackenzie reports 106 GW added in 2025, up 43% from 73 GW in 2024, and frames the year as the first time global annual installations crossed the 100 GW threshold.
  • BloombergNEF's figure runs higher: 112 GW (excluding pumped hydro) and 307 GWh of batteries added in 2025, a 48% year-over-year increase -- 6 GW above Wood Mackenzie's total and 4 GW above the IEA-sourced figure.
  • InfoLink Consulting measures the same year in energy terms only: 275.3 GWh installed in 2025, a 61.3% year-over-year jump -- a growth rate 13 to 21 percentage points steeper than the GW-based trackers, with China (167 GWh), the US (52.1 GWh), and Europe (25.3 GWh) as the top three markets.
