Shri Manohar Lal, Union Minister of Power, Housing & Urban Affairs, inaugurated today the commercial operation of Unit\u20132 (250 MW) of the 2000 MW (8\u00d7250 MW) Subansiri Lower Hydroelectric Project through virtual mode. He stated that the commissioning of this unit is \u201cnot just a technical achievement, but a testament to years of hard work, dedication, and teamwork.\u201d He further emphasized that the Subansiri Project stands as a symbol of India\u2019s commitment to clean and sustainable energy, supporting North-East India\u2019s growth, strengthening the national grid and advancing India\u2019s ambitious Net Zero goals.<\/strong><\/span><\/p>\n

The event was also attended by Shri Pankaj Agarwal, Secretary (Power), Shri Bhupender Gupta, CMD, NHPC, and other officers of the Ministry of Power and NHPC.<\/strong><\/span><\/p>\n

Shri Pankaj Agarwal lauded NHPC\u2019s achievement, highlighting that the Subansiri Lower Project will greatly improve energy supply in the North-East and serve as a testament to India\u2019s commitment to state-of-the-art, sustainable power systems. He emphasized timely commissioning of the remaining units, noting that the Subansiri Project will continue to play a pivotal role in India\u2019s transition to a Net Zero energy future while generating substantial socio-economic benefits for local communities.<\/strong><\/span><\/p>\n

Shri Bhupender Gupta, CMD, NHPC, expressed his heartfelt gratitude to the Ministry of Power, the Governments of Arunachal Pradesh and Assam, former NHPC leadership, the entire Subansiri Project team, all key stakeholders and partners for their dedicated support in making this milestone achievement possible. He further stated that the project will strengthen the national grid, support sustainable development in the North-East and provide reliable renewable energy to meet growing demand.<\/strong><\/span><\/p>\n

With the commissioning of Unit # 2, the Project is moving swiftly towards commissioning of 3 Units of 250 MW each shortly, followed by phased commissioning of the remaining four units during 2026-27. Upon full commissioning, the 2000 MW Subansiri Lower Hydroelectric Project will make a significant contribution to India\u2019s renewable energy capacity, enhance national grid resilience and usher in a new era in massive clean energy contribution.<\/strong><\/span><\/p>\n

<\/strong><\/span><\/p>\n

As India\u2019s largest hydropower project, the Subansiri Lower Project comprises 8 units of 250 MW each and is designed as a Run-of-the-River scheme with small pondage, diverting water through eight Head Race Tunnels (HRTs) to generate 7,422 million units (MU) of renewable electricity annually contributing significantly to India\u2019s green energy future. The project features the largest dam in North-East India, a 116-metre-high concrete gravity dam, which not only strengthens regional infrastructure and grid resilience but also enhances flood moderation and water management in the Subansiri River basin.<\/strong><\/span><\/p>\n

The Subansiri Lower H.E. Project exemplifies engineering excellence, featuring India\u2019s heaviest hydro generator rotors, largest stators and biggest main inlet valves, along with innovations such as the nation\u2019s largest aggregate processing plants, highest-capacity batching plant and first-ever use of Rotec\u2019s Tower Belt for dam concreting in India. As the first cascaded dam on the Subansiri River, it provides flood moderation with a 442 million cubic metre flood cushion. With a gross reservoir storage of 1,365 million cubic metres at FRL, about one-third remains empty during floods to absorb excess water and protect downstream communities.<\/strong><\/span><\/p>\n

<\/strong><\/span><\/p>\n

NHPC has implemented extensive riverbank protection and erosion control measures along the Subansiri River, completing works up to 30 km downstream and extending them up to 60 km. with an investment of about \u20b9522 crore. This has effectively stabilized the riverbanks for over five years. In addition, NHPC is supporting downstream community development through livelihood programs in piggery, sericulture and handloom, developed with IRMA. These initiatives, now in production, benefit around 5,000 women farmers and promote sustainable socio-economic development in the region.<\/strong><\/span><\/p>\n

Apart from supplying electricity to\u00a016\u00a0beneficiary states across India, the Subansiri Lower H.E. Project will provide free power allocations to Arunachal Pradesh and Assam, while the North-East region will receive 1,000 MW from the project, significantly strengthening regional energy availability.<\/strong><\/span><\/p>\n

The project has generated strong socio-economic benefits for the region by engaging around 7,000 local people daily during its construction phase and creating numerous direct and indirect jobs through contractors, service providers and local markets. With the commissioning of the project and the availability of continuous power, new small-scale industries are expected to emerge, further expanding employment and business opportunities while helping reduce outmigration. Additionally, the project is expected to boost tourism and enhance river navigation, contributing to long-term regional development and prosperity.<\/strong><\/span><\/p>\n

NHPC has invested around\u00a0\u20b9155 crore\u00a0in CSR initiatives across Arunachal Pradesh and Assam. Key works include constructing\u00a03,129 toilets\u00a0under Swachh Vidyalaya Abhiyaan, establishing a\u00a0Vivekananda Kendra Vidyalaya\u00a0in Dollungmukh serving\u00a0250 students,\u00a0providing safe drinking water facilities at\u00a01,841 locations\u00a0and RO water with sanitation at\u00a09 locations\u00a0and executing multiple rural development projects such as community halls, meeting halls, causeways and water supply schemes in nearby areas.<\/strong><\/span><\/p>\n

Over the last five decades, NHPC has successfully executed hydropower projects in some of the most challenging terrains and has diversified into solar, wind, and green hydrogen, reinforcing its position as a 100% Green Energy Company. With an installed capacity of 8333 MW from 30 power stations and 14 projects totaling 9704 MW currently under construction, NHPC continues to play a vital role in advancing India\u2019s clean energy transition and strengthening national energy security.<\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
