会社のニュース Global Energy Storage Installations Reach New Record in 2025

Global — 2025
Global energy storage deployment reached a new milestone in 2025, with battery energy storage systems (BESS) being installed at an unprecedented pace. Industry data shows that worldwide grid-scale battery installations continued to accelerate, driven by the rapid expansion of renewable energy and growing demand for grid flexibility.

Key Highlights
New battery storage capacity added in 2025 significantly exceeded previous annual records.

Utility-scale projects dominated the market, particularly in China, the United States, and Europe.

Lithium-ion batteries—especially LFP chemistry—remained the preferred technology due to safety, cost efficiency, and long cycle life.

Why It Matters
As solar and wind capacity increases globally, energy storage has become essential infrastructure rather than a supplementary solution. Large-scale batteries now play a critical role in peak-shaving, frequency regulation, and ensuring grid reliability.
