U.S. Grid-Scale Battery Production to Support 100% of Renewable Generating Capacity

The U.S. grid-scale battery manufacturing industry can now fully support the storage needs of wind and solar electricity generation, with battery storage expected to make up 28% of new U.S. power-plant capacity. By the end of 2025, U.S. factories had the capacity to produce about 70 GWh of finished grid storage systems annually, with projections to reach 145 GWh/year by the end of 2026. Despite challenges like limited domestic supplies of battery materials, the industry is advancing rapidly with battery recycling technologies and North American mining operations. Grid-scale storage systems are significantly enhancing the economics of renewable energy by storing excess power and ensuring a steady supply.
