    <description descriptionType="Abstract">&lt;p&gt;This research deals with the performance assessment and upgrading of Walga micro hydro&lt;br&gt;
power plant owned by government and fitted with cross flow turbine. Walga site is located in&lt;br&gt;
Oromia Regional State, South West Shoa zone, Wonchi Woreda Azer_Keransa Kebele. Walga&lt;br&gt;
site is located in a remote area. Currently, even though the village has the opportunity to get&lt;br&gt;
power from micro hydro power plant that was installed in 2014 by the Ministry of Water,&lt;br&gt;
Irrigation and Electricity, still the plant lacks reliability, sustainability and safety problems. The&lt;br&gt;
key reasons for the performance assessment and up grading of the existing Walga micro hydro&lt;br&gt;
power station were to know the efficiencies (turbine and unit efficiencies) and to determine the&lt;br&gt;
electrical power output of the plant. And also to know the power demand gap between supply&lt;br&gt;
side from the existing micro hydro power generator and demand side obtained from the village&lt;br&gt;
power demand assessment during the field survey. Therefore, performance assessment and&lt;br&gt;
testing, power need assessment of the community, determination of the power gap between the&lt;br&gt;
supply side from the existing Walga micro hydro power station and demand side were the&lt;br&gt;
purpose of this thesis work.&lt;br&gt;
In this study, performance assessment of existing Walga micro hydro power station was carried&lt;br&gt;
out and performance indicators were identified. Based on the performance test results and the&lt;br&gt;
village power demand assessment findings, the power demand gap of Walga village was known.,&lt;br&gt;
Two options were proposed to meet the power demand gap of the village. The first option is&lt;br&gt;
developing a PV/micro hydro hybrid power supply system and the second option is developing&lt;br&gt;
micro hydro resource existing at the site&lt;/p&gt;</description>
