Global battery storage additions reached 108 GW in 2025, reflecting the rapid expansion of the Battery Energy Storage System (BESS) market. This growth is supported by declining battery costs, the widespread adoption of lithium iron phosphate (LFP) technology, and increasing deployment across utility-scale and behind-the-meter applications.

The increasing integration of solar and wind power is further driving demand for BESS, as energy storage helps manage intermittent generation, improve grid flexibility, and support energy shifting and peak-demand management. Growing electricity demand from data centers, electric vehicles, and other electrified applications is also creating new opportunities for BESS deployment.

However, the market continues to face challenges, including regulatory uncertainty, grid connection delays, lengthy permitting processes, and financing risks. In addition, supply-chain concentration, trade barriers, safety concerns, and uncertainty surrounding long-term revenue models may increase project costs and restrict the faster deployment of BESS in certain markets.

 

Market Definition

A Battery Energy Storage System (BESS) is an electrochemical energy storage solution that stores electricity from sources such as the power grid, solar PV, or wind energy and discharges it when required.

A typical BESS consists of battery cells, a battery management system (BMS), a power conversion system (PCS), a thermal management system, and energy management software.

Key battery technologies include lithium ion battery, lead-acid battery , flow battery, and emerging sodium-ion battery, each offering different performance, cost, and storage characteristics.

 Energy storage solutions are increasingly being used for

• Storing excess renewable energy for use during periods of low solar or wind generation 

• Reducing grid congestion and deferring transmission and distribution upgrades 

• Supporting EV charging infrastructure by reducing stress on local electricity networks

• Supporting data center and AI infrastructure by providing reliable backup power, managing peak electricity demand, and improving power quality.

Drivers

Growing Demand for Flexible and Reliable Power Driving BESS Deployment 

The rapid expansion of solar and wind power is increasing the need for BESS to manage their intermittent generation, maintain grid stability, and improve grid reliability. In 2025, global renewable capacity additions reached a record 692 GW, including 511 GW of solar and 159 GW of wind capacity, meaning these two variable renewable sources accounted for around 97% of total renewable additions.

As renewable energy penetration increases, electricity generation does not always align with demand. For example, solar generation is highest during the daytime, while electricity demand often peaks in the evening, potentially resulting in renewable energy curtailment. 

BESS helps address this challenge by storing surplus electricity during periods of high generation and discharging it when generation is low or demand is high, thereby improving renewable energy utilization and enhancing overall grid flexibility.

Alongside renewable energy growth, the rapid expansion of data centers, cloud computing, and AI infrastructure is creating significant demand for BESS. These facilities require reliable and uninterrupted power, driving the need for solutions that provide backup power, manage peak demand, improve power quality, and support renewable energy integration. With its ability to respond within milliseconds, BESS is well suited to meet these high reliability requirements. 

For example, Google is supporting the development of the Steel River Energy Center in Arkansas, which is planned to include up to 2.9 GWh of battery storage alongside 2.5 GWdc of solar capacity. The project is expected to support the growing electricity demand from nearby AI data centers by storing excess solar generation and improving the availability of reliable power.

Restraints

Utility-scale BESS projects often face long interconnection queues, complex permitting requirements, and delays in obtaining grid access. These challenges can increase development and financing costs, delay construction, and postpone the start of commercial operations.

For example, in April 2026, Gresham House Energy Storage Fund delayed its GBP150 million earnings target after two UK BESS projects received grid connection dates in 2029. The 57 MW Lister Drive and 240 MW Ocker Hill projects will therefore be unable to begin construction until 2027, demonstrating how delayed grid connections can postpone project development, revenue generation, and expected financial returns.

In addition to grid-related constraints, BESS projects also face technical and safety challenges. Battery systems can be exposed to risks such as thermal runaway, fire, and equipment failures, which may result in stricter safety regulations, additional monitoring requirements, and higher project costs. Furthermore, lithium-ion batteries experience performance degradation over time and are generally less economical for long-duration or multi-day storage applications.

For example, in July 2026, a localized fire occurred at ACME Solar's Suryodaya BESS facility in Pokhran, Rajasthan, affecting four power conversion systems (PCS). The incident, caused by an IGBT-related short circuit, resulted in an estimated revenue impact of around INR 20 lakh, although no BESS containers were damaged. This highlights how equipment failures and fire risks can cause operational disruptions and financial losses, increasing the need for robust safety, monitoring, and thermal management systems. 

Market Opportunity

The increasing deployment of solar power is creating significant opportunities for solar-plus-storage projects. As solar generation increases, electricity prices can decline during periods of high daytime generation, while demand and electricity prices often rise during the evening. BESS can store low-cost or surplus solar electricity and discharge it during high-price periods, creating revenue opportunities through energy arbitrage, peak shaving, and energy shifting.

Beyond energy shifting, another emerging opportunity for grid modernization is the development of grid-forming battery systems. Unlike conventional grid-following batteries, grid-forming BESS can actively contribute to grid stability by providing black-start capability, fault ride-through, system strength, and voltage and frequency support.

The technology also creates opportunities to upgrade existing BESS fleets with grid-forming inverters, expanding the market for both new installations and retrofitting projects.

For example, in July 2026, Sungrow commissioned the 100 MW/400 MWh Santong BESS in Terengganu, Malaysia, which supports both conventional grid-following and advanced grid-forming operating modes. The system is designed to provide functions such as black start, islanded operation, and voltage and frequency regulation, demonstrating the growing commercial potential of grid-forming BESS as electricity systems integrate higher levels of renewable energy.

Segment Analysis

The global Battery Energy Storage System (BESS) market is segmented across two primary dimensions: connection type and battery type.
