Energy Storage Industry Outlook: Market Size, Policies & Trends
The global energy transition is accelerating, and energy storage has moved from a futuristic concept to a tangible investment hotspot and industry breakthrough. From capital market expectations to policy support, from AI-driven electricity consumption growth to structural changes in power markets, energy storage is becoming an indispensable key link in the energy system.
Global Energy Storage Installations Surge, J.P. Morgan Raises Forecasts
A recent research report from J.P. Morgan indicates that global battery energy storage system (BESS) installations are expected to grow by 40%–60% year-over-year in 2026, significantly higher than previous estimates. This upward revision reflects a strong market signal: the energy storage sector is entering a high-growth trajectory, far outpacing traditional energy growth rates.
Analysts point out that energy storage battery shipments and demand will continue to rise substantially from 2025 to 2026, with explosive growth in markets such as the United States, Europe, and China. The compound annual growth rate (CAGR) of global energy storage demand is projected at 30%–50%.
Key Drivers Behind the Growth
- ▶ Capital market confidence: Upgraded forecasts reflect the combined effect of supply-demand fundamentals, technology progress, and policy incentives.
- ▶ Scalability: The industry is transitioning from pilot projects to large-scale deployment, with gigawatt-hour level installations becoming common.
- ▶ Technology maturity: Lithium-ion battery costs have dropped significantly, making storage projects economically viable without heavy subsidies.
AI Computing Power Drives an “Electricity Revolution,” Indirectly Fueling Storage Demand
The biggest energy consumer in the AI era is not transportation or manufacturing, but data centers and supercomputing facilities. According to J.P. Morgan, the average energy load of AI data centers has grown from a few megawatts to tens of megawatts, with some large facilities consuming electricity equivalent to millions of households.
This unprecedented power demand pattern brings two major challenges: increased grid pressure, as traditional grids struggle to respond quickly to such high-density consumption, especially during peak hours; and an urgent need for flexible regulation capabilities. Energy storage plays a core role here—not just storing electricity, but enabling peak shaving and load shifting.
Trend to watch: Global data center electricity demand is expected to maintain high growth over the next decade, placing extreme demands on power systems and energy storage infrastructure.
Supply-Demand Resonance: Energy Storage Becomes the “New Infrastructure” of Power Systems
The market explosion is not only driven by demand but also by continuous improvements in supply-side technology and costs.
| Factor | Details |
|---|---|
| Battery Cost Reduction | Lithium-ion technology maturity and mass production have slashed system costs. Storage may account for ~30% of global lithium demand by 2026. |
| China Tender Data | In the first 11 months of 2025, cumulative storage tenders reached 112 GW / 364 GWh, up over 100% YoY. 2026 new installations may grow 80%. |
| US Market Growth | In the first three quarters of 2025, storage deployments nearly matched the full-year 2024 total, with ~27% YoY growth. |
This structural growth, fueled by both supply and demand, provides confidence for the entire industry chain and positions energy storage as a critical component of modern power systems.
Policy Dividends Continue: Energy Storage Integrated into Energy Strategy Core
Policy has always been a key driver for rapid market scaling. China has set a clear target: by 2027, the country’s new-type energy storage installed capacity should reach 180 GW, implying a near doubling in just two years. Meanwhile, policies promoting virtual power plants and smart grids are enhancing the value of storage by enabling market participation and multiple revenue streams.
Internationally, the US continues to support large-scale deployment through investment tax credits and storage incentives. In Europe, green energy and grid modernization policies create a stable institutional environment for storage growth. These policies not only improve project economics but also accelerate capital investment, making storage a core pillar of the energy transition.
Policy Highlights by Region
- ▶ China: 180 GW target by 2027, virtual power plant pilots, market-based ancillary services.
- ▶ United States: ITC extension, state-level storage mandates, FERC Order 841 compliance.
- ▶ Europe: REPowerEU plan, grid flexibility incentives, capacity market mechanisms.
Conclusion: Storage is Not Just a Supplement, It’s the Future Core of the Energy System
The global energy system is undergoing structural changes: from fossil fuels to renewables, from linear supply-demand to dynamic regulation. In this process, energy storage is not merely a “battery for electricity”—it is a stabilizer for the power grid, an enabler for energy markets, and an engine for capital growth.
With J.P. Morgan raising storage installation forecasts, AI driving new electricity demand tracks, and policy dividends continuing, the energy storage industry is entering a long-term high-growth cycle. For investors, enterprises, and policymakers, grasping the structural turning point is no longer about “whether to participate” but “how to position and capture value.”
