KEY HIGHLIGHTS

• India's domestic battery manufacturing accounts for less than 1% of its demand.
• The gap between demand and manufacturing capability is significant.
• Import dependence is cautioned against as a reason for slow deployment.
• NTPC has allocated 5 GWh of battery energy storage capacity.
• Achieving self-sufficiency in battery storage could take over a decade.

Introduction

In 2026, India's renewable energy sector is at a critical juncture. The growing capacity for renewable energy has created an immediate need to scale up storage systems. Industry stakeholders have highlighted a huge gap between the demand for battery cell components and the current capability to manufacture them.

Current Storage Capacity and Demand

According to industry members, India's domestic battery manufacturing currently accounts for less than 1% (2 GWh) of its approximately 260 GWh demand pipeline from competitive tenders in 2026. This gap underscores the urgent need for advanced storage solutions to balance solar generation with peak demand.

Expert Opinions

Sunkind India

Sunkind India founder and Managing Director Hanish Gupta emphasized the importance of battery energy storage systems (BESS) and pumped storage projects in expanding renewable capacity to meet rising electricity demand.

Premier Energies

Premier Energies Chief Business Officer Vinay Rustagi highlighted that batteries and other storage technologies are key to addressing the intermittency risk of solar power and unlocking its growth potential.

Volks Energie

Volks Energie CEO and co-founder Piyush Goyal cautioned against treating import dependence as a reason for slow deployment, stressing that the grid needs storage now to firm up the renewable capacity being added.

NTPC's Role in Storage Solutions

NTPC Chairman Gurdeep Singh shared that a storage system helps in both ways. During the daytime, renewable energy power generated can be stored and used in the absence of sunlight. NTPC has been allocated 5 GWh of battery energy storage capacity under the Viability Gap Funding scheme to optimize existing thermal generation and transmission infrastructure and ensure reliable and economical power supply during non-solar hours.

Wood Mackenzie's Research Insights

In its latest research, Wood Mackenzie said it would take more than a decade for India to achieve self-sufficiency in battery storage, as there is a huge gap between demand and current capability to manufacture essential battery cell components. The report noted that India has just 2 GWh of commissioned cell manufacturing capacity as of 2026, against China's cumulative capacity of 2,695 GWh, which controls between 85% and 98% of global capacity across every major supply chain component.

Global Comparison

Country	Battery Cell Manufacturing Capacity (GWh)	Market Share (%)
India	2	<1
China	2,695	85-98

Key Takeaways

• India's domestic battery manufacturing is insufficient to meet its renewable energy storage needs.
• The country is structurally dependent on imports for battery cell components.
• Achieving self-sufficiency in battery storage could take over a decade.

FAQ

What is the current status of India's battery cell manufacturing?

India's domestic battery manufacturing currently accounts for less than 1% of its renewable energy storage demand.

Why is there a gap between demand and manufacturing capability?

The gap is due to the significant difference between the current manufacturing capacity and the rapidly growing demand for battery cell components.

How does NTPC plan to address the storage challenge?

NTPC has allocated 5 GWh of battery energy storage capacity to optimize existing infrastructure and ensure reliable power supply.

Conclusion

In 2026, India's renewable energy sector faces a significant challenge in scaling up storage systems to meet its growing demand. While efforts are underway to address this gap, achieving self-sufficiency in battery storage will require substantial investment and time.
