  • An expert committee of the Environment Ministry approved the reconstruction of the Teesta-3 hydropower project in Sikkim.
  • The original 1,200 MW Teesta-III Chungthang hydroelectric dam was destroyed in a flash flood on October 3-4 of 2023.
  • The flood, triggered by a Glacial Lake Outburst Flood (GLOF) from the South Lhonak Lake, washed away the 60-metre-tall concrete dam.
  • The new structure will be a 118.64-metre-tall concrete gravity dam.
