The US battery storage market reached a record high in Q2 2026 with 20.2 gigawatt-hours of new capacity added.
The US battery storage market achieved its largest quarterly increase on record during the second quarter of 2026, adding 20.2 gigawatt-hours (GWh) of new capacity. This growth represents more than 10% of all energy storage capacity currently installed in the United States. The majority of this expansion came from utility-scale projects, which reached a total of 165 GWh across the country. Growth was concentrated in states endorsed by Donald Trump, with Arizona, Texas, and Utah leading the installations. Arizona recorded its strongest quarter ever with 6.2 GWh, while Texas added 3.8 GWh. The administration announced that utility-scale capacity grew from 88 GWh to 165 GWh during the first 18 months of the Trump administration. Manufacturing also expanded, with Tesla bringing its third Megafactory online in Texas. This facility is designed to produce 50 GWh of Megapack batteries annually. Despite this growth, the administration issued an executive order directing the Department of Energy to restrict transactions involving power equipment from China and other countries to manage supply chains.
