Arunachal's 58,000 MW hydropower can power India's clean energy future: Dy CM Mein
Synopsis
Key Takeaways
Arunachal Pradesh Deputy Chief Minister Chowna Mein on 19 September 2025 asserted that the northeastern state — holding an assessed hydropower potential of nearly 58,000 MW, or roughly 40% of India's total hydropower potential — is uniquely placed to anchor the country's energy security and accelerate its shift away from fossil fuels. He made the remarks at a national conference in New Delhi, calling responsible development of the state's water resources a strategic national priority, not merely a regional one.
Key Remarks at the Viksit Bharat Finance Conference
Mein, who also holds the Power and Non-Conventional Energy Resources portfolios in the Arunachal government, was speaking on the second day of the two-day conference titled 'Financing India's Journey Towards a Viksit Bharat', organised by the Union Ministry of Finance at Bharat Mandapam, New Delhi. The session he addressed was focused on 'Financing the Energy Transition', also attended by Union Finance and Corporate Affairs Minister Nirmala Sitharaman.
Mein argued that hydropower offers something solar and wind energy cannot: stability and reliability. 'Hydropower is critical to achieving India's clean energy goals, providing stable and dependable renewable power while complementing solar and wind energy,' he said, underlining the base-load advantage of large hydro projects.
Installed Capacity Growth and the Subansiri Milestone
The Deputy Chief Minister highlighted substantial progress in the sector. Arunachal Pradesh's installed hydropower capacity has grown from 405 MW in 2016 to around 1,200 MW, and has since climbed to 2,270 MW following the recent commissioning of the Subansiri Lower Project — a landmark development for a state whose hydro story has long been marked by delays and environmental disputes.
Notably, around 19,000 MW is already at various stages of development, with 4,880 MW currently under active construction. This positions Arunachal as one of the most active hydropower development zones in South Asia.
Decade of Hydropower 2025–35: Targets and Investment
Mein outlined an ambitious state roadmap under the 'Decade of Hydropower 2025–35', which envisions commissioning 19 GW of new hydropower capacity over the decade, backed by an investment pipeline of approximately ₹1.9 lakh crore. The broader target is to harness 40 GW of hydropower capacity by 2047, aligned with India's centenary independence goals.
The sector is projected to generate more than 30,000 direct and 16,000 indirect employment opportunities, making it a significant driver of inclusive economic growth in a state where large-scale employment options remain limited.
Transmission, Private Sector, and Centre's Role
Mein stressed that power generation alone is insufficient — transmission infrastructure must advance in parallel. Given Arunachal Pradesh's remote and challenging terrain, he called for integrated planning that links hydropower projects with high-capacity transmission systems and renewable energy aggregation infrastructure, ensuring efficient evacuation of power to both the state grid and the national interstate network.
He also pushed for greater private sector participation in unlocking the state's untapped potential and sought continued Union government support through targeted incentives and facilitation mechanisms. This comes amid a broader national debate on whether large hydro — often mired in environmental clearance delays and displacement concerns — can be fast-tracked without compromising ecological and community safeguards.
India's Clean Energy Transition: What This Means
India has committed to achieving 500 GW of non-fossil fuel capacity by 2030. Large hydropower, reclassified as a renewable source under Indian policy in 2019, is increasingly seen as an essential balancing element alongside variable renewables. Arunachal's untapped potential — most of it on the Brahmaputra and its tributaries — represents one of the largest undeveloped hydro reserves in the world. If the state's targets are met, it could add tens of gigawatts of dispatchable clean power to the national grid before 2047, significantly reducing India's dependence on thermal capacity.
The pace of private investment and the resolution of transmission bottlenecks will likely determine whether the 'Decade of Hydropower' vision translates into grid-connected reality or remains a planning document.
