  "abstract": "<p>This research deals with the performance assessment and upgrading of Walga micro hydro<br>\npower plant owned by government and fitted with cross flow turbine. Walga site is located in<br>\nOromia Regional State, South West Shoa zone, Wonchi Woreda Azer_Keransa Kebele. Walga<br>\nsite is located in a remote area. Currently, even though the village has the opportunity to get<br>\npower from micro hydro power plant that was installed in 2014 by the Ministry of Water,<br>\nIrrigation and Electricity, still the plant lacks reliability, sustainability and safety problems. The<br>\nkey reasons for the performance assessment and up grading of the existing Walga micro hydro<br>\npower station were to know the efficiencies (turbine and unit efficiencies) and to determine the<br>\nelectrical power output of the plant. And also to know the power demand gap between supply<br>\nside from the existing micro hydro power generator and demand side obtained from the village<br>\npower demand assessment during the field survey. Therefore, performance assessment and<br>\ntesting, power need assessment of the community, determination of the power gap between the<br>\nsupply side from the existing Walga micro hydro power station and demand side were the<br>\npurpose of this thesis work.<br>\nIn this study, performance assessment of existing Walga micro hydro power station was carried<br>\nout and performance indicators were identified. Based on the performance test results and the<br>\nvillage power demand assessment findings, the power demand gap of Walga village was known.,<br>\nTwo options were proposed to meet the power demand gap of the village. The first option is<br>\ndeveloping a PV/micro hydro hybrid power supply system and the second option is developing<br>\nmicro hydro resource existing at the site</p>",
