Tourism is one of the key incomes of Ethiopia. To increase this income from the current 10% national gross domestic product to high value, electrifying rural tourist attractive areas are very important. Tana Lake Island is one of the best tourist areas in Ethiopia. The present study relates the main renewable energy resources to the electrical production in the small islands in Lake Tana. In this paper different hybrid schemes were performed i.e PV/Wind/Battery and PV/Wind /pumped hydro. To compare the above hybrid scheme HOMER software used as-as optimization and sensitivity analysis tool As a result, from economical point of view, PV/Wind/pumped hydro hybrid system is found as low cost of energy about $0.151/kWh which is much lower than diesel generators and previously studied PVbattery hybrid systems which is estimated to cost about $0.325/KWh.
