US Energy Storage Hits Quarterly Record at 5.6 GW

The American Clean Power Association and Wood Mackenzie released a report announcing that US energy storage installations hit a quarterly record of 5.6 GW in Q2 2025.

  • Primary announcement: The report documents 5.6 GW of total Q2 2025 installations, with 4.9 GW utility-scale, 608 MW residential (132% YoY growth), and 38 MW CCI; it forecasts 87.8 GW by 2029 and flags a potential 10% drop in 2027 for utility-scale due to FEOC battery sourcing rules.
  • Additional details/background: The release names Texas, California, and Arizona as >1 GW adders in Q2; notes three projects in Oklahoma (SPP) came online—the first in three years; warns that projects not meeting milestones by end of 2025 risk exposure to changing ITC battery-sourcing regulations; cites OBBBA/ITC preservation but a possible 16.5 GW reduction in the five-year buildout under headwinds.
