Assessment of Cause of Huluka Micro Hydro Power Scheme Failure and Estimation of Its Potential

Abstract

In Ethiopia, several Micro hydropower (MHP) schemes were constructed between the year 1950 and 1970. One of the Micro hydropower schemes constructed within this period was Huluka Micro-hydropower. However, it is no longer operational nowadays due to some issues and problems. Hence, this research study aimed to assess the causes of failure and estimating the potential power of Huluka micro hydropower. The overall existing condition of the components of the Micro hydropower plants evaluated as to functionality and its physical measurements, including the identification of the potential factors responsible for the failure of the Micro hydropower. From the flow duration curve of Huluka River, it indicated a maximum and the minimum potential power of the scheme of about 1313.23kw, and 274.41 kW, respectively. Hence, it is postulated that rehabilitation of Huluka MHP could provide a solution to the current shortage and interruption of power supply in Ambo town as well as its surrounding areas.
