The National Crisis Management Committee (NCMC) under the chairmanship of Cabinet Secretary, Shri Rajiv Gauba met on February 7, 2021 to review the situation arising out of the natural disaster in Uttarakhand caused by glacial burst on Nanda Devi in Chamoli district.
- The glacial burst led to the rising of water levels in the river Rishiganga, which washed away the Rishiganga small hydro project of 13.2 MW.
- The flash flood also affected the downstream hydro project of NTPC at Tapovan on the river Dhauliganga, which is a tributary of the river Alaknanda.
- While the Rishiganga hydel project had an installed capacity of 13.2 megawatts (MW), the 520 MW NTPC Tapovan-Vishnugad project on the Dhauliganga was much larger. Both sites have been virtually washed away.
