US Grid Energy Storage Blasts Past 40 Gigawatts, Crushing 2025 Goal

The US grid energy storage industry didn't just meet its ambitious target — it smashed through it. Back in 2017, storage companies set what seemed like an eye-popping goal: 35 gigawatts of batteries connected to the US power grid by 2025, representing an eightfold increase in capacity.

By the third quarter of 2025, the figure stood at 40 gigawatts and rising, according to a report by Canary Media. This achievement is crucial for the renewable energy transition because solar and wind power are intermittent — batteries store excess energy generated during sunny or windy periods for use when conditions are calm.

Remarkably, this growth continued even as the Trump administration phased out tax credits for renewables in the 'Big Beautiful Bill.' However, battery storage tax credits were preserved, recognizing that grid reliability depends on energy storage regardless of the energy source.
