A roundup of the biggest projects, financing and offtake deals in the energy storage sector that we have reported on this year. Tesla's energy storage plant in Shanghai's Lin-gang Special Area commenced operation on Feb 11, as the assembly line started the production of the first Megapack unit. The Megapack, which is an advanced battery system designed for large-scale energy projects, can store more than 3,900. Summary: Explore groundbreaking energy storage projects worldwide that are redefining renewable energy adoption. From mega-batteries to innovative thermal systems, discover how these initiatives address grid stability and decarbonization goals. Global Energy Storage Trends Driving Innovation The. U. Accelerated by DOE initiatives, multiple tax credits under the Bipartisan Infrastructure Law and. 2025 was a pivotal year for energy storage: Global grid-scale BESS deployments surged by 23%, adding a staggering 92 GW / 247 GWh worldwide, driven by falling costs of lithium-iron-phosphate (LFP) batteries, escalating demand for grid stability, and aggressive net-zero commitments. Despite policy changes and uncertainty in the world's two largest markets, the US and China, the sector continues to grow as developers push forward with larger and larger utility-scale projects.
