 Recent Developments & Market Pulse

• According to research from Bloomberg NEF (BNEF), global energy storage deployments (excluding pumped hydro) are on track to hit approximately 92 GW/247 GWh in 2025, marking about a 23 % year-on-year growth.
• The International Renewable Energy Agency (IRENA) reports that costs for battery-energy-storage installations fell dramatically: fully installed costs dropped from ~US$2,571/kWh in 2010 to about US$192/kWh in 2024.
• Regionally, in India, major industry players are investing in grid-scale BESS to support renewable integration and decentralised reliability.
• In Europe, according to Reuters, battery storage capacity is projected to increase five-fold by 2030 and attract investment approaching the €80 billion mark.
• In the US, strategic utility-scale projects are underway, such as a 160 MW/320 MWh battery storage system developed near Houston to support local grid reliability.

Market Size, Share, Trends, Forecast by 2031 (Bullet Points)

Key trends:

• Declining battery system costs (e.g., >30 % reduction for 2-hour systems in 2024 vs 2023).
• Shift from purely utility-owned systems toward residential and commercial adoption.
• Growth of advanced chemistries beyond lithium-ion, and greater system durations (4-hours, 8-hours, longer).
• Regional diversification: Asia-Pacific leading, North America & Europe scaling rapidly, Middle East & Africa emerging.

Share dynamics by region:

• Asia-Pacific accounts for the largest portion of market share currently, owing to high renewables deployment and grid modernisation efforts.
• North America and Europe remain key growth regions, with strong policy support and utility investment.
• Emerging markets (Latin America, Middle East & Africa) expected to contribute incremental share by 2031.

By 2031, the Battery Energy Storage System market is expected to:

• Drive further cost reductions and system efficiency improvements.
• Expand in duration, moving from short‐duration (2–4 h) systems to long‐duration storage solutions.
• Facilitate higher shares of renewables, enabling grid flexibility and resilience.
• Offer new revenue streams through grid services, energy arbitrage, and capacity markets.

Trends & Drivers

• Declining battery cost: The cost of installed battery energy storage systems has dropped sharply—by over 90 % from 2010 to 2024 according to IRENA.
• Renewable energy integration: As solar and wind become larger parts of the power mix, the role of storage to manage intermittency grows.
• Grid modernisation & flexibility needs: Utilities and grid operators increasingly deploy battery storage for frequency regulation, peak-shaving, reserve capacity, and delaying grid upgrade investments.
• Regulatory & policy support: Many governments are providing incentives, mandates, and markets for energy storage, making adoption more attractive.
• Technology evolution: Move toward longer-duration storage, alternative chemistries, better safety and recyclability are shaping future solutions. 

Conclusion

The global Battery Energy Storage System (BESS) market stands at the forefront of the global energy transition—bridging the gap between intermittent renewable generation and consistent power demand. As the world pushes toward net-zero targets, battery storage is not merely supporting renewables; it is redefining how power systems operate, integrate, and deliver.
