After a historic 2025, when global BESS capacity surpassed 250 GW and overtook pumped hydropower, momentum is set to accelerate in 2026. Key markets are expanding, emerging regions are stepping into the spotlight, and battery storage is increasingly replacing gas. . We expect 63 gigawatts (GW) of new utility-scale electric-generating capacity to be added to the U. power grid in 2025 in our latest Preliminary Monthly Electric Generator Inventory report. This amount represents an almost 30% increase from 2024 when 48. It represents lithium-ion batteries (LIBs)—primarily those with nickel manganese cobalt (NMC) and lithium iron phosphate (LFP) chemistries—only at this time, with LFP becoming the primary. . The battery energy storage market continues its rapid growth, reshaping power systems worldwide. The first battery, Volta's cell, was developed in 1800. EIA's latest monthly “Electric Power Monthly” report (with data through November 30, 2025), once again. . Our annual report on electricity generation capacity in the United States breaks down the current and imminent generation of electricity by type of fuel, location, and ownership type. In 2024, the United States. .
