In the present paper, the second option of refurbishment and
uprating has been explored. A case study with fresh hydrological
investigations and new capacity determination has been worked
out in this paper. The new capacities arrived at are much more
beneficial than commissioning a new hydro power plant which are
capital intensive as well as have long gestation period in addition to
other constraints like rehabilitation problems of local population
and environmental issues. This is quite beneficial capacity addition
program for a hydro facility with minimum investment in minimum
time.
