In a significant boost to India’s clean energy and grid stability infrastructure, International Finance Corporation (IFC), the private sector arm of the World Bank Group, has committed an investment of Rs 460 crore ($55 million) to IndiGrid for developing the country’s largest battery energy storage system (BESS). The investment marks IFC’s growing focus on energy transition projects that enhance renewable integration, reduce grid instability, and accelerate decarbonisation goals.
Project Overview and Strategic Significance
The proposed project will see IndiGrid, India’s first listed power sector infrastructure investment trust (InvIT), develop a grid-connected BESS facility with a storage capacity of 500 MWh. This will make it the largest battery energy storage installation in India, supporting the nation’s aim to integrate higher volumes of renewable power while ensuring grid reliability and frequency control.
Key highlights of the project include:
- Developer: India Grid Trust (IndiGrid)
- Financier: International Finance Corporation (IFC)
- IFC Commitment: Rs 460 crore ($55 million)
- Project Capacity: 500 MWh grid-connected battery energy storage system
- Location: Likely in renewable energy-rich states such as Gujarat or Rajasthan (final site under evaluation)
- Primary Objective: Renewable energy time-shifting, peak load management, and frequency regulation
Why Battery Energy Storage Systems are Critical for India
As India pursues its target of achieving 500 GW of non-fossil fuel energy capacity by 2030, storage solutions have emerged as a cornerstone for grid stability and efficient renewable integration. The intermittency of solar and wind power often causes fluctuations in grid frequency, impacting reliability and power quality.
Key benefits of BESS projects:
- Renewable Integration: Smoothening out generation variability from solar and wind sources by storing excess power during surplus periods and releasing it during peak demand hours.
- Grid Stabilisation: Providing frequency and voltage regulation, reactive power support, and black-start capabilities in the event of grid failure.
- Cost Optimisation: Reducing curtailment of renewable generation and lowering reliance on expensive peaking thermal power plants.
- Energy Security: Enhancing domestic grid resilience, especially critical during extreme weather events, disasters, or sudden demand spikes.

IndiGrid has steadily expanded its asset base since its IPO in 2017, acquiring operational transmission lines and solar power assets. The foray into battery storage marks its entry into advanced grid solutions and energy transition infrastructure.
IFC’s Strategic Role and Sustainable Finance Agenda
The Rs 460 crore investment aligns with IFC’s broader strategy to:
- Mobilise private capital for green infrastructure in emerging markets
- Enable developing economies like India to meet their Paris Agreement goals
- Promote battery storage as a commercially viable sector with scalable business models
IFC has been actively investing in India’s renewable sector across solar, wind, hybrid power, and green bonds. Its involvement provides confidence to other global investors and multilateral agencies to support India’s clean energy value chain.
Policy Push for Battery Storage in India
The Government of India has unveiled multiple policies and incentives to drive BESS adoption, including:
- Production Linked Incentive (PLI) Scheme for Advanced Chemistry Cell (ACC) manufacturing worth ₹18,100 crore to promote domestic battery manufacturing.
- Viability Gap Funding (VGF) scheme for battery storage projects to reduce tariff costs for distribution companies (DISCOMs).
- Grid Code Amendments mandating energy storage participation in ancillary services markets for frequency control.
These policy measures aim to achieve the government’s target of creating at least 27 GW of battery storage capacity by 2030, as outlined in India’s National Electricity Plan.
Market Opportunity and Growth Potential
Industry experts estimate that India’s battery storage market could attract investments worth $20-25 billion by 2030, driven by:
- The need to integrate over 300 GW of new solar and wind capacity
- Growing electric vehicle charging infrastructure requiring grid-scale storage support
- Declining battery costs globally, making projects commercially viable without heavy subsidies by late 2020s
IndiGrid’s Future Strategy and Sector Impact
IndiGrid has signalled its intent to expand aggressively into energy storage, green hydrogen-ready transmission lines, and hybrid renewable parks, positioning itself as a comprehensive energy infrastructure platform.
The company’s key strategic priorities include:
- Developing battery storage as an investable infrastructure asset class, leveraging its InvIT model to attract institutional capital.
- Partnering with technology leaders in battery manufacturing and storage software management for efficient project delivery and operations.
- Exploring hybrid renewable-plus-storage projects to provide round-the-clock clean power solutions to industrial and commercial consumers.
Expert Opinions
Market analysts view IFC’s commitment as a landmark development that validates battery storage’s bankability in India.
- Positive View: IFC’s involvement enhances project credibility, accelerates sector maturity, and brings global best practices to design, financing, and execution.
- Cautionary View: Experts advise continuous monitoring of battery technology risks, lifecycle management, and tariff competitiveness vis-à-vis pumped hydro storage or gas peaker plants.
Conclusion
IFC’s Rs 460 crore investment in IndiGrid for India’s largest battery energy storage system underscores the transformational shift towards a sustainable and reliable power sector. As battery costs decline and grid services markets mature, such projects are set to play a critical role in achieving India’s ambitious renewable energy and decarbonisation goals while ensuring uninterrupted power for its rapidly growing economy.
