The global grid-scale battery market is undergoing rapid expansion, with DataM Intelligence reporting a rise from $6.84 billion in 2023 to an estimated $38.46 billion by 2031. This represents a CAGR of 25.74% between 2024 and 2031.
Grid-scale batteries are large-capacity energy storage systems designed for utility and industrial use. They play a critical role in stabilising electricity networks, balancing demand fluctuations, integrating renewable energy, and providing backup power. Technologies include lithium-ion, flow, and solid-state batteries, serving utilities, commercial and industrial sectors worldwide.
Recent developments in the grid-scale battery market highlight the pace of adoption. In the United States, September 2025 saw utility-scale installations hit a quarterly record with 4.9GW added, marking 63% year-over-year growth and powering around 3.7 million homes. By October, Portland General Electric had completed three major facilities in Oregon, adding 475MW and 1.9GWh. In November it was reported that batteries met a record 37.2% of California’s evening peak demand on 12 October.
Europe is also accelerating. September 2025 revenues for large-scale storage climbed sharply, while October saw Repono acquire a 200MW/404MWh project in Romania. November marked the opening of Europe’s largest battery storage site at Blackhillock, Scotland, underscoring the UK’s role in renewable integration.
Drivers of grid-scale battery growth include rising investment in renewable energy, falling battery costs, and supportive government policies promoting clean energy storage.
