The battery energy storage market continues its rapid growth, reshaping power systems worldwide. After a historic 2025, when global BESS capacity surpassed 250 GW and overtook
Tesla''s new Megapack 3 and Megablock solutions promise to revolutionize utility-scale energy storage by boosting capacity to 5 MWh per unit, slashing soft costs, and enabling 1 GWh
Global deployments of BESS in the first half of 2025 have surged by 54%, reaching 86.7 GWh of capacity. These systems capture electrical energy in batteries and release it on demand,
Global installed energy storage capacity by scenario, 2023 and 2030 - Chart and data by the International Energy Agency.
In 2025, capacity growth from battery storage could set a record as we expect 18.2 GW of utility-scale battery storage to be added to the grid. U.S. battery storage already achieved record growth in 2024
A zero-carbon future by 2050 would require 930 GW of storage capacity in the U.S 33, and the grid may need 225-460 GW of long duration energy storage (LDES) capacity. 34 Hydrogen, CAES, and PHS
BloombergNEF expects cumulative energy storage capacity in 2035 to reach 2 terawatts (7.3 terawatt-hours) – eight times the level in 2025. Utility-scale projects continue to dominate
Energy Capacity (MWh): The total amount of electricity that can be stored and discharged over time. This determines how long the system can operate at its rated power. For example, a 100
Solar, wind, and batteries are set to supply virtually all net new US generating capacity in 2026, according to the latest EIA data.
What is energy storage? Energy storage is the capturing and holding of energy in reserve for later use. Energy storage solutions for electricity generation include pumped-hydro storage,
