Power Corporation (KPCL) had
investigations and pre-feasibility studies on mini- hydro prospects
associated with irrigation dams at Brindavan, Kabini, Nugu, and
Harangi in the Cauvery river basin, and Mudhol, Malaprabha, and
Devrebelerkere in the Krishna river basin. Investigations had also
been done for over ten canal drop prospects along: (i) the Left
Bank Canal on the Tungabhadra scheme which draws water from a major
tributary of the Krishna river; (ii) the Visveswaraiah Canal which
draws water from the KRS reservoir (i.e., the Brindavan Dam) on the
Cauvery river; and (iii) the Shahpur Branch Canal which distributes
water from the Narayanapur Reservoir on the Upper Krishna scheme.
Altogether, the KPC collaborated with ESMAP to review proposals on
seven dam based prospects, one prospect at the Attehala diversion
weir, and five canal drop prospects, including a cluster comprising six
drops on the Shahpur BC (Map - IBRD 22784). The prospects covered in
this study have a total annual power generation potential of the order
of 140 GWh. This estimate excludes the potential yield of the
Tungabhadra LB Canal which already is under development by the KPC.
in planning and layout were recommended for each of the schemes.
As an example the case of Maddur illustrates preliminary design procedure of Canal based scheme
and use of closed conduit for byepass,
Brindavan illustrates the use of existing
sluices at dams and Kilara the elimination of by
