Energy Storage for Renewable Energy Integration in India (StoREin)
India aims to integrate a total of 500 gigawatts of non-fossil energy capacity by 2030. With regard to this, the project supports the creation of favourable framework conditions for the introduction of various energy storage technologies and integrated solutions at the distribution grid level in India. Furthermore, it contributes to bringing the energy transition closer to the local level. In this way, decentralised solutions for the provision and use of renewable energies can make an important contribution to carbon neutrality. This is also particularly important given the fact that large-scale renewable energy projects are increasingly coming under criticism at the community level. At the same time, the project opens up a wide range of opportunities for local and regional stakeholders by promoting a climate change-adapted, economically viable and socially inclusive renewable energy industry.

State of implementation/results
- As a first demonstration project under StoREin, a first-of-its-kind 12 MW battery energy storage system featuring grid-forming inverter technology is set to connect to Delhi’s distribution network. The StoREin project supported the Delhi distribution company (DISCOM) in conducting a comprehensive feasibility analysis of the BESS system, served as the bid manager for tendering the demonstration project, and facilitated onboarding of a developer for its implementation. This demonstration will validate the grid-forming inverters' ability to deliver essential grid support services greater renewable energy integration at the distribution level.
- In consultation with the Indian Political Partner, the StoREin project is exploring additional demonstration projects based on the next generation energy storage and battery technologies for e.g. sodium ion, micro emulsion flow batteries etc.
- Two International Benchmarking Studies on Energy Storage (European Union, United States, Australia, United Kingdom, Canada etc.) have been worked on
- “Global Review of Energy Storage Technologies” (to be released in April 2026): Provides a neutral assessment of energy storage technologies and their role in enabling reliable and flexible power systems with high shares of renewable energy. The report serves as a reference for India to understand international best practices, technology adoption strategies, and market trends in energy storage.
- Report on "Global Insights on Energy Storage Policies: Best Practices and Lessons Learned" synthesizing granular analysis across these countries and analysing high-impact policy takeaways and global best practices for replication in Indian markets.
- Study on “Storage Systems Technology Landscape in India” (expected June 2026): Comprehensive mapping of energy storage technologies and their potential applications across grid services in India’s evolving power system.
- The StoREin project has launched an Indian R&D Forum for Grid-Connected Energy Storage Systems on 20 January 2026 with participation from the German Embassy New Delhi, Indian Ministry of New and Renewable Energy, and key sector stakeholders. The forum establishes a collaborative platform connecting academia, industry, policymakers, and research institutions to promote knowledge exchange, evidence-based research collaboration, and dialogue on energy storage technologies, grid integration, and policy frameworks.
- Capacity-building initiatives have covered training of 97 professionals including 18 women.
- Report on “Skill Gap Assessment of Battery Energy Storage Systems (BESS) in India”: Assesses technical and operational roles across the BESS value chain, including competencies in system design, grid integration, and operation & maintenance, with recommendations for targeted workforce development.
- 2-day training on “Advanced Battery Storage Systems- Design, Control and Integration at Distribution Level” conducted at Indian Institute of Technology Bombay, covering BESS architecture, power electronics, control strategies, grid integration, and techno-economic assessment.
- 3-day BESS Capacity Building programme conducted for officials of Gujarat DISCOM, focusing on system design, grid services, project implementation, and operational safety.
- As part of the knowledge repository, an Energy Storage Portal named UrjaSanchay is currently being developed under the project.
