Koldam HEP-I: NTPC, state forest department to review submergence data

NTPC's first ever hydroelectric project (HEP), the 800 MW Kol Dam, still faces an uncertain future. The power major, along with the state forest department, has now been directed to resurvey the submergence data with respect to the site selected for the project and furnish a report on measures to safeguard as many trees are possibly.

  • The power major is likely to expedite the matter, given its criticality to determining the parameters of the crucial impounding reservoir for the project, in consultation with the Ministry of Environment and Forests (MoEF). 
  • This comes against the background of an environmental impasse that threatens to strangle the project. Notably, the Standing Committee of National Board of Wildlife (NBWL) had recently rejected NTPC's proposal to divert 124 ha of land, as about 50,000 trees stand endangered due to the project.
  • The project, located in the Bilaspur district of Himachal Pradesh, envisages the construction of a 163 m high main dam, with a rock and gravel fill and clay core, a 1600 m long penstock tunnel of 6.45 m diameter, surface-type powerhouse, two diversion tunnels of 900m and 920m length and Francis turbines. The project has an estimated cost schedule of Rs 4527.15 crore.
