Capacity Slipped : 806 MW
Reasons for slippage
Schedule commissioning of the project got
delayed because of leakage in Head Race Tunnel
during filling of Water conductor system/ spinning
of the machine.
Commissioning during the year got delayed due
to flash flood (AILA) on 26 th May, 2009 of the
project area. Also, progress of works got affected
due to frequent disruption of works because of
the local agitation.
Single shift working & Visa problem of Chinese
Engineers affected the erection, testing &
commissioning schedule
Slow progress of erection of Penstock due to
extended monsoon period and steep slope delayed
the commissioning.
Commissioning of the units got delayed due
to flash flood on 08.10.2009 flooding the
power house and affected the already installed
equipment.
Delay occurred in completion of Head Race
Tunnel & surge shaft works due to bad geology.
Power evacuation works are also delayed due to
forest clearance issue.
Poor geology in Head Race Tunnel has delayed
the completion of works.
