How battery storage is transforming the power grid

It's hard to overstate how fast the battery energy storage industry is growing and the impact it's having on the power sector. In 2025, US utilities and independent developers added 17.75 gigawatts of large-scale battery storage capacity, up 52% from 2024. Multiple forecasts suggest another 100 GW or more of large-scale battery capacity will come online in the US through 2030.

To the extent utilities and power producers can meet the electricity demand projected to surge in the coming years, batteries are going to be critical to the solution, supporting data centers, electric vehicles, domestic factories and other sources of increased load.

In this episode, Dan Testa digs into these trends with Noah Roberts, executive director of the Energy Storage Coalition, and Mateo Jaramillo, CEO of Form Energy, a company building and deploying long-duration batteries using innovative iron-air technology.
