    <dct:description>&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;</dct:description>
