NHPC’s 2,000 MW Subansiri Lower HEP achieves dam top level

Moving towards completion of 2,000 MW Subansiri Lower hydroelectric project (HEP), NHPC Limited has completed the dam top level of EL 210 M in all the blocks.

NHPC Limited commenced construction work of Subansiri Lower project in January 2005 after receiving forest clearance in 2004. However, due to the agitation and protests by local stakeholders, the project construction work was stalled from December 2011 to October 2019, and construction commenced thereafter. The construction of all the major components viz. dam, power house, hydromechanical works etc. are progressing fast towards completion. The completion of dam to top level is the biggest milestone at Subansiri Lower Project. More than 90 per cent of total project work has already been completed. After monsoon, balance work of radial gates will be completed and electricity generation will start by end of 2023-24. On completion, Subansiri Lower project will generate around 7,500 million units of power annually on 90 per cent dependable year.
