This paper has presented the economic-analysis results
and calculated potential outcomes to study future installation
of micro hydro power (MHP) plants in seven selected
irrigation canals of Chia-Nan Irrigation Association in
Taiwan. According to the potential results, it is found that the

(C) South Line (D) Ben-Chi Lake 3+974
(E) Bon-Pi Branch Line (F) Mar-Do No. 5 Water Gate

computed potential values are very easy and quick to identify
which canal is the best one for installing MHP plants in the
future. The payback period is severely affected by the
effective water head than the water flow rate. It can be
concluded that to select an irrigation canal with higher water
head for installing MHP plants is more important than to
select a canal with larger water flow rate.
