Battery Storage Capacity Set to Nearly Double This Year

U.S. battery storage capacity, which has grown in the past few years, could increase by 89% by the end of this year—if all new systems come on line as intended, according to the U.S. Energy Information Administration.

What’s going on: “Developers currently plan to expand U.S. battery capacity to more than 30 gigawatts (GW) by the end of 2024, a capacity that would exceed those of petroleum liquids, geothermal, wood and wood waste, or landfill gas.”

Where it’s concentrated: The wind- and solar-generating fleets of two states—California and Texas—account for most of the growth.

  • “California has the most installed battery storage capacity in the U.S., with 7.3 GW, followed by Texas, which has 3.2 GW.”
  • All the other states have a combined total of approximately 3.5 GW of installed battery storage capacity.

How it works: Batteries store excess power during periods of low electricity demand and release it when demand surges.  

What’s next: “Developers expect to bring more than 300 utility-scale battery storage projects on line in the United States by 2025, and around 50% of the planned capacity installations will be in Texas.”

Our view: “Battery storage plays an important role in an all-of-the-above energy strategy, allowing greater use of renewable power on the grid by ensuring that excess generation can be stored for later use,” said NAM Vice President of Domestic Policy Brandon Farris.

  • “With greater battery capacity coming on line, Congress and the administration should put forth comprehensive permitting reform to ensure we can continue timely buildouts of much-needed additional power generation and the transmission lines to ensure the power generation can go where it is most needed.”
