Global Battery Energy Storage System (BESS) Market and Forecast to 2031 - Analysis by Application (Utility, Commercial and Industrial, Residential), Connection Type, Battery Type, Energy Capacity, Ownership Model, Components, and Geography

Battery Energy Storage System (BESS) Market Size

The battery energy storage system (BESS) market is one of the fastest-growing segments of the global power sector, expanding at a CAGR of 31.50% between 2023 and 2026E. Battery storage remained the fastest-growing power technology worldwide in 2025, with approximately 108 GW of new storage capacity added during the year. Total installed battery storage capacity is now nearly eleven times higher than 2021 levels.

Growth in the global BESS market is driven by accelerating renewable energy deployment, rising electricity demand from AI-powered data centers, rapid battery cost reductions and increasing investment in grid modernization. The growing share of intermittent solar and wind generation has significantly increased the need for grid-scale energy storage that can maintain grid stability, balance peak loads and ensure uninterrupted power supply. At the same time, the rapid expansion of artificial intelligence infrastructure and hyperscale data centers is pushing global electricity consumption higher, prompting utilities and power developers to invest heavily in battery storage for reliable and flexible energy supply.

Deployment remains concentrated in large-scale projects and in a few leading markets. Around 80% of newly installed battery storage capacity in 2025 was utility-scale, and China alone contributed nearly 60% of global capacity additions. The market continues to benefit from advances in lithium-ion battery technology, supportive government policies and expanding investment in renewable energy and storage infrastructure across both developed and emerging economies.

Key Drivers Shaping the Global BESS Market

Rising Battery Demand from Electric Vehicles and Stationary Storage Deployments

Global battery demand has expanded rapidly in recent years, driven by strong electric vehicle adoption and accelerating stationary storage deployments. EV battery demand grew by more than 30% in China and nearly 20% in the United States in 2024. Utility-scale stationary storage installations grew strongly over the same period, as grid operators increasingly deployed battery systems to support renewable energy integration and grid reliability. Global lithium-ion battery deployment in 2025 was nearly six times higher than 2020 levels, reflecting the combined pull of electric mobility and energy storage.

Falling Battery Prices Accelerating Large-Scale BESS Deployment

Declining battery costs remain a primary enabler of growth in the battery energy storage system market. Average battery prices fell by approximately 8% during 2025, driven by manufacturing scale expansion, ongoing technological advancements, supply chain optimization and intensifying competition among battery cell manufacturers. This sustained cost reduction is directly improving the economics of utility-scale and commercial battery storage projects across major markets, and industry projections indicate storage costs could fall by a further 25% by 2035.

Renewable Energy Capacity Expansion Driving Demand for Grid-Scale Battery Storage

Rapid global deployment of solar and wind energy is significantly increasing the need for battery energy storage systems to manage intermittency and ensure reliable electricity supply. Global solar installations reached a record 664 GW in 2025, according to SolarPower Europe. As solar output concentrates in daytime hours, batteries are increasingly used to shift generation into evening peaks, making solar-plus-storage the standard configuration for new utility-scale projects in many markets.

Advanced Economies Maintaining Dominance in Global Battery Storage Capacity Additions

Historically, more than 95% of global battery storage capacity additions have been concentrated in China, the United States and the European Union. In 2025, China alone contributed nearly 60% of worldwide additions. These markets continue to lead global deployment thanks to strong renewable energy targets, supportive regulatory frameworks, mature power markets and substantial investment in grid-scale storage infrastructure.

Emerging Markets Accelerating Battery Energy Storage Investments

Emerging economies across the Middle East, Africa, Latin America and parts of Asia Pacific are increasingly investing in battery energy storage systems to support renewable integration, improve grid stability and meet rising electricity demand. Expanding solar and wind capacity, alongside grid modernization programs and energy transition policies, is expected to accelerate BESS deployment across these regions during the forecast period. Large projects such as BYD's 2.6 GWh solar-plus-storage order in Chile show how quickly these markets are scaling.
