2000 MW Subansiri Hydroelectric Project in Assam Set to Supply Power to 17 States by March 2025

Approximately 3,000 workers are engaged in continuous shifts for the 2000 MW Subansiri Lower Hydroelectric Project in Assam. This project is set to become India's largest conventional power project, according to officials. Located on the Assam-Arunachal Pradesh border in Dhemaji district, three units of this NHPC project will begin operations by March next year, as stated by NHPC Executive Director and Project Head Rajendra Prasad.

The Subansiri Lower Hydroelectric Project is nearing completion, with 95-96% of the work finished. It aims to supply electricity to 17 states, including Rajasthan. Three units, each with a capacity of 250 MW, are expected to be operational by March 2025. Prasad mentioned that a total of eight units will be installed under this project, providing power to various states.

Power Distribution Across States

Once fully operational, the project will distribute 533 MW to Assam and 274 MW to Arunachal Pradesh. Other northeastern states like Manipur, Meghalaya, Nagaland, Tripura, and Mizoram will receive a combined total of 198 MW. Additionally, northern states such as Haryana, Punjab, Rajasthan, Uttar Pradesh, and Chandigarh will get 387 MW.

The western states of Gujarat, Madhya Pradesh, Chhattisgarh, Maharashtra, and Goa are set to receive a total of 613 MW from this project. Prasad also highlighted that detailed project reports for two additional projects of 1650 MW and 1710 MW on the Subansiri river's other banks are being prepared. This development will make it the largest hydropower project on any river in India.

Project Challenges and Progress

Construction for the Subansiri Lower Hydroelectric Project began in January 2005 under NHPC Limited. However, local protests halted progress from December 2011 until October 2019. The National Green Tribunal's clearance allowed work to resume in October 2019. Due to this eight-year delay, costs escalated from Rs 6,285 crore in 2005 to approximately Rs 26,000 crore now.

The project's pace has increased thanks to efforts by staff and support from the Centre. A total of Rs 22,000 crore has been spent so far as it enters its final phase. "We have challenged Subansiri river," Prasad stated. "It is a completely indigenous project." He added that once fully commissioned, it will generate Rs 4,000 crore annually and provide direct employment for 5,000 people.

Community Engagement and Future Prospects

NHPC has addressed all local issues and is actively involved in CSR projects in Gerukamukh village. These initiatives include building schools and hospitals to enhance villagers' livelihoods. The project not only promises significant economic benefits but also aims to improve community welfare through these efforts.
