Key Developments

• In December 2025, ArcelorMittal announced the development of three new renewable energy projects in India, comprising a combined 1 GW of solar and wind capacity, supported by an investment of US$ 900 million. The projects, located across Maharashtra, Rajasthan, and Gujarat, are expected to double the company’s renewable energy capacity in the country to 2 GW upon completion. The electricity generated from these assets will be supplied to AMNS India, ArcelorMittal’s steelmaking joint venture, supporting its transition toward cleaner and more sustainable energy usage.
• In September 2025, WRI India, in collaboration with the Confederation of Indian Industry (CII), launched the CI-NERGY Alliance – Steering Energy Transitions to accelerate clean energy adoption across India’s commercial and industrial (C&I) sector. The initiative was officially unveiled at Connect Karo 2025 held in New Delhi and aims to support businesses in transitioning toward sustainable energy solutions through collaboration, policy engagement, and knowledge sharing.

Alternative Energy Market Segmentation

Based on the energy source

• Solar Energy
• Wind Energy
• Hydropower
• Geothermal Energy
• Bioenergy
• Others

Based on the energy source, solar energy is anticipated to be the leading segment in the alternative energy market, primarily driven by its scalability and rapidly improving cost competitiveness. Solar power can be deployed across utility-scale, commercial, and residential settings, making it more accessible than other renewable sources. Continuous advancements in photovoltaic efficiency, combined with simplified installation processes and declining balance-of-system costs, are accelerating adoption across both developed and emerging economies. In addition, supportive government policies, net-metering frameworks, and corporate sustainability commitments are encouraging widespread solar deployment. The ability of solar energy to integrate seamlessly with energy storage systems and smart grids further strengthens its market leadership, positioning it as the most commercially attractive and fastest-growing renewable energy source globally.

Based on the technology

• Grid-connected Systems
• Off-grid / Distributed Systems

Based on the technology, grid-connected systems are anticipated to lead the alternative energy market, driven by their ability to support large-scale power generation and seamless integration with national electricity networks. Grid-connected systems enable utilities and independent power producers to transmit renewable energy efficiently over long distances, ensuring stable supply and improved load management. The growing expansion of solar and wind farms, coupled with investments in transmission infrastructure and smart grids, is strengthening the adoption of grid-connected solutions. Additionally, favorable regulatory frameworks, feed-in mechanisms, and long-term power purchase agreements encourage large-capacity installations. The trend toward digital grid management and advanced monitoring further enhances system reliability, positioning grid-connected systems as the dominant technology in the alternative energy market.

Based on the application

• Power Generation
• Heating and Cooling
• Transportation
• Others

Based on the application, power generation is expected to dominate the alternative energy market, primarily driven by the global transition toward clean electricity production. Utilities and governments are increasingly prioritizing renewable power generation to replace coal- and gas-based plants, reduce emissions, and meet long-term energy security goals. Large-scale deployment of solar, wind, and hydropower projects is strengthening renewable electricity capacity across regions. Additionally, electrification of end-use sectors such as industry, buildings, and transportation is increasing demand for clean power at the grid level. Continuous improvements in grid infrastructure, energy storage integration, and digital power management are further supporting renewable-based power generation, making it the most established and commercially significant application segment within the alternative energy market.

Based on the end user

• Residential
• Commercial
• Industrial
• Utilities
• Others
