Global battery storage deployment has entered a period of unprecedented growth. Annual installations increased by roughly 40% in 2025, reaching 108 GW, with utility-scale projects accounting for around 80% of newly deployed capacity. Behind this expansion lies a rapidly maturing global supply chain, and China has become its primary engine. Understanding this market trajectory is essential for companies planning procurement, partnerships, and long-term investment strategies.
