Abstract: Small and mini hydropower systems demonstrate an attractive solution with the help of pump as turbine (PAT) for hydropower generation with lower costs and less impact on the environment. African is having a major challenge in connection with desires for energy. There is the need to increase energy security particularly in the rural areas. The rapid growth of renewable energy capacity in the region contains all the potentials that can answer to quite a lot of these problems. Small-scale hydropower is one of the most cost-effective energy technologies to be considered for electrification in the region since it is economical with other significant benefit if implemented. This paper focuses on the PAT for small-hydropower to Africa since the establishment of widespread small hydropower by the use of PAT can help overcome the current power crisis and play a role in the economic progress of the Region. The paper draws attention on the importance of implementing Pump as turbine for small hydropower development in Africa. It highlights on hydropower potential sites in the region, challenges, the characteristics of pump as turbine has been discussed and draw conclusion on PAT for small scale hydropower development as one of the most cost-effective solution.

Keywords: Hydropower, energy, small hydropower, Pump as Turbine, Potential.
