The journey towards a cleaner energy future is driven not only by breakthrough technologies but also by the platforms that bring innovators, policymakers, investors and industry leaders together. For nearly two decades, Renewable Energy India Expo or REI Expo has served as one of those defining platforms, evolving alongside India’s renewable energy ambitions and becoming Asia’s largest exhibition dedicated to clean energy. As the industry moves towards an era where renewable generation and energy storage must grow hand in hand, REI Expo continues to create opportunities that extend far beyond the exhibition floor—fostering partnerships, enabling investments and accelerating the adoption of next-generation technologies.
In this exclusive conversation with Shweta Kumari, Sub-Editor, The Battery Magazine, Julian Thomas, Portfolio Director – Energy & Battery Sector, Informa Markets India Pvt. Ltd., shares how the 19th edition of REI Expo, co-located with the 4th edition of The Battery Show India, is set to redefine the scale and impact of renewable energy exhibitions in the region. From strengthening global collaborations and promoting India’s manufacturing ecosystem to creating new opportunities across solar, battery storage and clean energy technologies, he explains why REI Expo 2026 is poised to become a landmark event in India’s energy transition.
REI Expo has grown into Asia’s largest renewable energy exhibition. What factors have contributed to its continued growth and relevance over the years?
The Renewable Energy India (REI) Expo has established itself as Asia’s premier renewable energy exhibition, with its 19th edition scheduled for October 22-24, 2026, at India Expo Mart Limited (IEML), Greater Noida.
Several key factors have driven its sustained growth and industry relevance:
REI Expo was founded with a clear vision to support India’s renewable energy ecosystem and national energy objectives. As India’s renewable energy sector has experienced exponential growth, the expo has evolved into a true reflection of the nation’s clean energy success story. This alignment with national priorities has made REI Expo an essential platform for stakeholders across the energy value chain.
Global Reach with Local Impact
As part of Informa Markets’ global portfolio, REI Expo leverages international expertise in exhibition organization while maintaining deep local market understanding. This combination enables the event to support bilateral trade growth and connect India’s renewable energy sector with global markets and technologies.
The expo’s continued expansion in size, exhibitor participation, and visitor engagement directly mirrors the sector’s remarkable growth trajectory, making REI Expo an indispensable annual gathering for Asia’s renewable energy community.
Support for Make in India
REI Expo has been instrumental in advancing India’s Make in India campaign by:
- Facilitating partnerships between international and Indian firms
- Encouraging foreign companies to establish manufacturing facilities in India
- Supporting local employment and industrial growth
- Creating opportunities for technology transfer and collaboration
Integrated Battery Ecosystem
Recognizing the critical importance of energy storage, REI Expo is co-located with The Battery Show India (4th edition), part of the globally renowned Battery Show series with editions in North America and Stuttgart. This strategic co-location:
- Covers the complete energy value chain from generation to storage
- Attracts hundreds of international suppliers from China, Korea, Japan, and a substantial German Pavilion
- Strengthens India’s battery manufacturing and storage ecosystem
- Provides comprehensive solutions for the evolving energy landscape
There is a powerful shift underway in how the world views renewables, no longer a choice but a compulsion. How does REI 2026 go beyond showcasing technology and translate this urgency into ground-level action, tangible business outcomes, and accelerated adoption for the stakeholders on the floor?
India’s renewable energy targets are ambitious, and government policies are increasingly supportive. Yet many stakeholders struggle to navigate the complex landscape of subsidies, compliance requirements, state-level incentives, and evolving regulations. REI 2026 addresses this critical gap by creating direct interfaces between policymakers and implementers. State level association don’t just visit the expo—they provide concrete information on land availability, grid connectivity timelines, and incentive structures that project developers need to make investment decisions.
In a development that signals the maturation of Asia’s renewable energy ecosystem, REI Expo has forged a strategic partnership with SNEC China, creating an unprecedented alliance between the two largest renewable energy exhibitions in Asia. Both events command respect globally for attracting the best exhibitors and most serious buyers in the solar and storage sectors. This collaboration represents more than a business arrangement—it’s a recognition that the world’s renewable energy future will be shaped in Asia, and that India and world, must work together to accelerate the global energy transition.
India’s renewable energy sector is witnessing unprecedented global convergence as REI Expo & The Battery Show India emerges as the epicenter of international collaboration and business opportunities.
A strong European delegation demonstrates the continent’s commitment to partnering with India’s energy revolution, while Germany’s dedicated pavilion underscores the nation’s strategic interest in Indo-German renewable energy cooperation. Australia’s Maidan Pavilion further reinforces bilateral ties, highlighting shared sustainability goals and technological expertise.
The REI Expo host the largest Bio Energy Pavilion ever assembled, positioning bioenergy as a critical pillar of India’s diversified renewable portfolio. This comprehensive showcase explores cutting-edge biomass technologies, waste-to-energy solutions, and sustainable fuel innovations that align perfectly with India’s agricultural economy and circular economy aspirations.
How do you see India’s renewable energy sector evolving over the next five years, and what role will industry platforms like REI play in supporting that growth?
Over the next five years, India is expected to accelerate toward its ambitious target of 500 GW of non-fossil fuel capacity by 2030. Solar and wind will continue dominating installations, but the real game-changer will be energy storage solutions. Battery technology adoption will surge as India addresses grid stability and intermittency challenges, making events like The Battery Show India increasingly critical for knowledge transfer and technology partnerships.
Decentralized renewable energy systems will proliferate, particularly in rural and semi-urban areas. Bioenergy will gain prominence as India leverages its agricultural waste potential, while offshore wind projects will commence, opening new frontiers. Electric vehicle integration with renewable grids will create synergies between mobility and energy sectors.
As India marches toward its ambitious renewable targets, REI Expo will be remembered by the nation and industry as the stepping stone that made energy independence achievable. It is where India’s golden energy story is not just told—it is written, deal by deal, partnership by partnership, innovation by innovation.
What message would you like to share with industry leaders, policymakers, investors, and professionals planning to attend REI Expo 2026?
India’s renewable energy and energy storage industries are set to witness one of the most significant gatherings of the year as REI Expo and The Battery Show India join forces to create an unprecedented platform for innovation, collaboration, and business growth.
