Conclusions
The potential of electricity generation by a small hydropower plant on Tuwan
River, which ﬂows across TAR (Tuwan Agribusiness Resort) is presented by this
project. In particular, the ﬁnancial and GHG savings of the proposed case are
compared to the full power supply using diesel generator sets. The following
conclusions are drawn from the analysis:
•
According to local measurements, Tuwan River may provide to this project an
estimate of at least 21 kW power generation potential with a Kaplan turbine
throughout the year.
•
The hydropower project provides GHG emissions reduction of 307.4 tCO2
equivalent.
•
A net present value (NPV of 568,178 USD (11% discount rate), internal rate of
return (IRR) of 68.1% and beneﬁt-cost ratio of 6.34 with incentives of a 50,000
USD grant and a tax holiday are obtained in favour of the mini-hydropower
plant.
The analysis shows that it is economically and environmentally attractive to
pursue a mini-hydro project in this location. Thus, it is safe to invest more funds to
conduct an extensive feasibility study with the aim of convincing fund (grant and
loan) providers to invest in the project.
