NHPC Expected to Start Construction of 2 GW Lower Subansiri Hydro Plants in October

NHPC  a State-run hydro powergiant is likely to start of the 2,000 MW Lower Subansiri power plant in October this year as it has taken the required approval from the Assam government foe commencement.

NHPC had signed a MOM with Arunachal Pradesh for setting up the project in 2010. However, since the project falls in the territories of both Arunachal Pradesh and Assam, the latter's approval was needed as well.
