New Delhi: NHPC Limited on Thursday said it has completed over 90 percent construction of its Subansiri Lower Hydroelectric project. It is constructing the 2,000 MW power project located in Assam-Arunachal Pradesh.

"More than 90 percent of total project work has already been completed. After monsoon, balance work of radial gates will be completed and electricity generation will be started by the end of Financial Year 2023-24," the company said in a statement.

NHPC Limited commenced construction work on the multi-crore project in January 2005 after forest clearance on October 12, 2004.

"As one of the biggest achievements towards completion of the 2,000 MW Subansiri Lower HE Project, the dam top level of EL 210 M has been completed in all the Blocks today on June 29, 2023.
