India’s renewable energy sector is experiencing a remarkable growth trajectory in 2025, underscored by record investment inflows and a significant surge in capacity additions. In August 2025 alone, investments in renewable energy projects surged to $1.235 billion, reflecting a 45% increase year-on-year, signaling robust investor confidence in India’s clean energy transition. This momentum is supported by strategic government policies, innovative financing mechanisms, and a broadening energy portfolio that now includes not just solar and wind, but also energy storage, green hydrogen, and electric mobility infrastructure.
The first half of 2025 saw India add an unprecedented 22 gigawatts of renewable energy capacity—an impressive 57% increase compared to the previous year—with solar power accounting for over 18 gigawatts. This rapid expansion aligns with India’s ambitious target of installing 500 gigawatts of non-fossil fuel-based capacity by 2030. Policy instruments such as the Production Linked Incentive (PLI) scheme and flagship initiatives like PM Surya Ghar are accelerating domestic manufacturing alongside large-scale deployments. Additionally, capacity allocation for battery energy storage systems demonstrates the sector’s focus on grid stability and the integration of variable renewable sources.
REI India
Within this broader industry context, events like the 18th Renewable Energy India Expo (REI) play a catalyst role by facilitating partnerships, technology, and real-time investment decisions. As the sector evolves towards more integrated solutions, the expo co-located shows on battery technology and energy storage underscore the critical role of innovation and collaboration in sustaining India’s clean energy momentum.
The 18th edition of the Renewable Energy India (REI) Expo 2025, held from October 30 to November 1 at the India Expo Mart in Greater Noida, emerged as Asia’s largest and most influential platform for the clean energy sector. Organised by Informa Markets India, the event assembled over 1,035 leading brands and attracted 58,986 trade visitors, 306 speakers, and 1,602 delegates from across the globe, reinforcing its position.
At the core of REI Expo 2025’s strategy is the deliberate alignment with India’s Vision 2030 and the Make in India initiative, positioning the expo as a convergence hub where global clean energy innovations meet India’s robust policy framework. The event’s distinction was further underscored by the partnership with the State of Odisha, highlighted as the Partner State, showcasing Odisha’s rapid progress in renewable manufacturing sectors such as green hydrogen and large-scale solar projects. This facilitated high-level interactions between industrial leaders and government officials, catalyzing long-term investment partnerships.
Functioning as a comprehensive ecosystem, the expo combined a six-track conference format designed to expedite real-time investment decisions with an expansive exhibition floor featuring a record number of new innovations across solar, bioenergy, and energy storage sectors. The concurrent hosting of The Battery Show India and the inaugural Energy Storage India 2025 integrated under one roof marked India’s largest multidisciplinary platform to address the growing demand for clean energy and advanced storage solutions critical to the country’s energy transition. The battery show alone attracted 378 brands and over 18,000 trade visitors, reflecting the rapid scaling of India’s electric mobility and battery manufacturing industries.
In responding to the escalating corporate commitments toward decarbonisation and net-zero targets, REI Expo ensured these discourses translated to tangible outcomes by facilitating strategic partnerships, operational discussions, and technology showcases focused on scalable solutions. The inclusion of Residential Welfare Associations (RWAs) and grassroots engagement through initiatives such as the Solar Installer Premier League extended the event’s impact by enhancing adoption of decentralized solar energy infrastructure at the community level, thus supporting India’s broader clean energy ambitions.
The business impact of REI Expo 2025 is quantified by significant investment commitments, with estimates surpassing ₹1,800 crore particularly in the bioenergy segment, driven by innovations in compressed biogas and waste-to-energy technologies supported by global technology leaders and policy makers. This infusion of capital and technology signals a maturation of the renewable bioeconomy in India, crucial for energy security, emission reductions, and rural employment generation.
Way ahead
Looking ahead, Informa Markets is determined to position the REI Expo not merely as Asia’s largest renewable energy marketplace by scale but as the region’s most transformative platform. The expo’s legacy increasingly pivots on fostering trust, nurturing sectoral collaboration, and embedding sustainability into India’s energy and economic growth story. The visible participation of women entrepreneurs and inclusivity in roles such as solar rooftop installations underscores the event’s holistic approach to industry growth and societal impact.
