In a significant breakthrough for the 2000MW Subansiri Lower HE Project in India, the dam's top level, reaching an elevation of 210m, has been successfully completed across all blocks. This accomplishment marks a major stride towards the project's completion.
NHPC Limited, the project's developer, initiated construction work in January 2005 following forest clearance received on October 12, 2004. However, due to local stakeholder agitation and protests, the construction was halted from December 2011 until October 2019. The resolution of legal issues by the National Green Tribunal (NGT) paved the way for project construction to resume on October 15, 2019. Currently, the construction of critical components such as the dam, powerhouse, and hydromechanical works is progressing rapidly, bringing the project closer to fruition.
The achievement of reaching the dam's top level stands as a significant milestone for the Subansiri Lower Project. With over 90% of the total project work already completed, this milestone underscores the project's substantial progress. Following the monsoon season, the remaining work on radial gates will be finalized, enabling electricity generation to commence by the end of the 2023-24 financial year.
Upon completion, the Subansiri Lower Project is anticipated to generate approximately 7500 million units of electricity annually, accounting for a 90% dependable year.
