Abstract: Off-grid generation options have been simulated for remote villages in Cameroon using a load of 110kWh/day and 12kWp. The energy costs of proposed options were simulated using HOMER, a typical village load profile, the solar resource of Garoua and the flow of river Mungo. For a 40% increase in the cost of imported power system components, the cost of energy was found to be 0.296€/kWh for a micro-hydro hybrid system comprising a 14kW micro-hydro generator, a 15kW LPG generator and 36kWh of battery storage. The cost of energy for photovoltaic (PV) hybrid systems made up of an 18kWp PV generator, a 15kW LPG generator and 72kWh of battery storage was also found to be 0.576€/kWh for remote petrol price of 1€/l and LPG price of 0.70€/m3. The micro-hydro hybrid system proved to be the cheapest option for villages located in the southern parts of Cameroon with a flow rate of at least 200l/s, while the PV hybrid system was the cheapest option for villages in the northern parts of Cameroon with an insolation level of at least 5.55kWh/m2/day. For a single-wire grid extension cost of 5000€/km, operation and maintenance costs of 125€/yr/km and a local grid power price of 0.1€/kWh, the breakeven grid extension distances were found to be 15.4km for micro-hydro/LPG generator systems and 37.4km for PV/LPG generator systems respectively. These results could be used in Cameroon's National Energy Action Plan for the provision of energy services in the key sectors involved in the fight against poverty.
