Abstract

The aim of this research was to study the feasibility of installing a very low head (VLH) hydro turbine downstream of the  Nam Pung hydropower plant thereby increasing the potential of renewable energy resources of the Electricity Generating Authority of Thailand (EGAT). The water head level was limited to less than 2 meters and the flow rate to below 5 m3/ s due to site constraints. The selected hydro turbine was an axial flow turbine with an efficiency of 86.4%. The power output was 84.61 kW. Investment analysis was subsequently applied to estimate feasibility of the project. Analyses of results showed that the project is worthwhile in terms of investment. The payback period of actual price was 0.83 and 0.88 years and for the general price, it was 3.68 and 4.04 years, with annual interest rates of 6.75% and 12.625% respectively. The projected project lifespan is 25 years.
