Major trends in the forecast period include integration of renewable-linked energy storage networks, expansion of ev-charging paired storage solutions, advancement of IoT-connected bess monitoring platforms, development of AI-optimized grid storage systems, automation in large-scale storage manufacturing.

The ongoing renewable energy revolution is anticipated to drive the growth of the battery energy storage system (BESS) market in the future. Renewable energy is derived from natural resources that replenish more quickly than they are consumed. Its increasing utilization helps reduce emissions of pollutants and greenhouse gases that contribute to climate change. In the context of BESS, energy is captured from the electrical grid or renewable sources like solar and wind and stored using battery storage technology. For example, in February 2024, reports from the World Resources Institute, a U.S.-based research organization, indicated that a record 31 GW of solar energy capacity was installed in 2023, reflecting a 55% increase from 2022. This brought the total installed solar capacity to around 161 GW, supplying approximately 5% of the nation’s electricity. Therefore, the growing demand for clean and renewable energy is expected to significantly boost the battery energy storage system market.

Major companies in the battery energy storage system market are creating new products, such as integrated energy storage system solutions, to achieve a competitive advantage. Integrated Energy Storage Systems (ESS) encompass comprehensive solutions that merge various components and technologies into a single system for storing electrical energy. For example, in November 2023, Caterpillar Inc., a U.S.-based engineering equipment manufacturing firm, introduced the Cat ESS suite, an integrated Energy Storage System (ESS) solution. This suite features scalable and modular designs suitable for diverse energy system applications, including generator set transient assist, grid integration and support, energy time-shifting, power stabilization, power factor correction, and renewable energy integration. The standard module, which serves as the basic unit, is a 20-foot module equipped with lithium-ion batteries, Caterpillar's bi-directional inverter, and an isolation transformer. The Cat ESS suite is designed to provide customers with grid stabilization and energy time-shifting technologies to support site loads with scalability.

In July 2025, Lyten Inc., a US-based company specializing in advanced materials and next-generation battery technologies, acquired Europe’s largest battery energy storage systems manufacturing facility from Northvolt for an undisclosed amount. Through this acquisition, Lyten aimed to enhance its battery energy storage production capabilities and accelerate the deployment of its lithium-sulfur-based energy storage solutions. Northvolt AB is a Sweden-based company that manufactures and assembles battery systems, including those for stationary energy storage (BESS).

Major companies operating in the battery energy storage system market are BYD Company Limited, TotalEnergies SE, Huawei Technologies Co. Ltd., Hitachi Ltd., Tesla Inc., General Electric Company, Siemens AG, Panasonic Corporation, Contemporary Amperex Technology Co. Limited, LG Chem Ltd., Schneider Electric SE, Honeywell International Inc., ABB Ltd., Johnson Controls International plc, NEC Corporation, Toshiba Corporation, NextEra Energy Inc., Eaton Corporation plc, Samsung SDI Co. Ltd., Vistra Energy Corp., AES Corporation, Sungrow Power Supply Co. Ltd., Enersys, Fluence Energy Inc., Amprius Technologies Inc., Sunverge Energy Inc., Envision Energy Inc.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have impacted the battery energy storage system market by increasing the cost of imported lithium cells, battery modules, inverters, and control components, particularly from major Asian suppliers. Utility-scale front-of-the-meter projects and commercial behind-the-meter installations are most affected due to high component volume requirements. However, tariffs are stimulating domestic cell production, localized supply chains, and innovation in alternative battery chemistries, helping strengthen long-term market resilience and regional manufacturing competitiveness.
