The US Had a Big Battery Boom Last Year

The United States experienced a record-breaking surge in battery storage capacity in 2025, adding 57 gigawatt hours (GWh) to the grid—a nearly 30% increase from the previous year—according to a report by the Solar Energy Industries Association (SEIA). This growth is notable given the political challenges faced by renewable energy under the second Trump administration, which cut tax credits for wind and solar but largely spared battery incentives. The expansion of battery storage is significant enough to power over five million homes annually, and the market is expected to grow another 21% in 2026, adding an additional 70 GWh. This boom contrasts sharply with less than a gigawatt of total storage capacity less than a decade ago. Texas stands out as a key driver of this growth, with its deregulated and independent power grid fostering a competitive market environment that has allowed solar and battery storage to flourish despite federal resistance. Texas solar energy met over 15% of demand during the summer of
