Out of the four uprating options available from Table 4, first and
second options are more attractive as these will require minimum
investment as same water conductor systemwill suffice the purpose
and same existing power evacuation equipment will serve the purpose.
However, for third and fourth options, a complete over hauling
of the power plant right from intake, water conductor system,
reservoir, flashing chambers, additional or enhanced surge tank and
new electro-mechanical equipment will be required. The financial
analysis carried out with the results given in Tables 5e10 suggests
which of the uprating option is most suitable and economical.
