Market Overview

To combat global warming and abnormal weather patterns, as well as to achieve carbon neutrality, countries worldwide are striving to phase out coal and nuclear power and deploy renewable energy plants. Energy storage systems (ESS) help stabilize the power generated by these plants and manage maximum loads. This is expected to improve power quality and energy usage efficiency. Storing the power generated by renewable energy plants in ESS and using it during peak demand hours improve the usage rate of power plants and transmission infrastructure. ESS has also been implemented as a distributed power source to provide a stable power supply in the event of grid deterioration due to aging infrastructure or blackouts during a disaster.

The estimated global ESS market size is 293,992 MWh in 2024, based on manufacturers’ shipment capacity. This substantial growth is due to the increased demand for self-power generation and consumption, greater deployment of renewable power plants (e.g., photovoltaic and wind power), and policies and support that encourage ESS adoption worldwide.
Implementation of ESS is trending upward in 2025, driven by demand in North America, Europe, and China for grid-scale and corporate/commercial ESS. In the United States, large-scale grid ESS deployment is increasing rapidly, especially in California, Texas, and Nevada—states that have made progress in implementing renewable power plants. Germany, Italy, France and Britain are major deployment countries projected to drive the market growth in Europe.
Many residential ESS deployments occur in detached houses, particularly in conjunction with photovoltaic power systems, in regions where electricity prices are relatively high, such as Europe, North America, Japan, and Australia.

Consequently, based on manufacturers’ shipment capacity, the global ESS market is expected to reach 376,108 MWh, which is 127.9% of the size of the previous year. Grid-scale ESS has the largest share by installed location (application), accounting for over 80% of the total, or 331,403 MWh.

Noteworthy Topics

To achieve carbon neutrality, the deployment of renewable power plants is likely to accelerate worldwide. This will likely lead to an increased implementation of ESS, which aim to stabilize electricity quality and make effective use of excess power.
Secondary battery and ESS manufacturers are developing advanced material technology and optimized system designs to produce higher-performance products and reduce costs. These developments will enhance the effectiveness of ESS deployments and boost the market.
Based on manufacturers’ shipment capacity, the global ESS market size is forecast to reach 735,473 MWh by 2033.
