notizie sull'azienda Global Grid-Scale BESS Deployments Up 36% in First 9 Months of 2025

Global — late 2025
Data from recent market tracking show that global grid-scale battery energy storage system (BESS) deployments surged by 36% during the first nine months of 2025 compared with the same period in 2024. A total of 49.4 GW / 136.5 GWh of new BESS capacity was commissioned over this period.

What’s Behind the Surge

• In September 2025 alone, the industry added 4,637 MW / 11,466 MWh of new BESS capacity — continuing a strong monthly deployment trend.

• The boom is driven by expanding renewable generation worldwide, increasing demand for grid flexibility, and competitive pricing of lithium-ion batteries.
• Many of these new storage systems are designed to pair with renewable generation — helping stabilize grids as solar and wind power grow.Many of these new storage systems are designed to pair with renewable generation — helping stabilize grids as solar and wind power grow.

Why It Matters

This sharp rise in battery storage deployment signals that BESS is no longer fringe technology — it is becoming central infrastructure for power grids globally. As more renewables come online, storage is essential for ensuring reliability, balancing supply/demand, and enabling wider renewable integration.
