Abstract

Harnessing the power of water to generate electricity is one of the most cost-effective and sustainable methods of energy production. Small hydropower plants are gaining prominence due to their ability to generate electricity with lower hydraulic heads and smaller flow rates, making them suitable for a wider range of applications. However, the growing global population and its associated demands for water for drinking, agriculture, and industrial purposes are putting increasing pressure on rivers. It is crucial to strike a balance between utilizing river waters for hydropower generation and preserving its availability for essential human needs. The study explored and assessed the small-scale hydropower potentials in the Vhembe District Municipality. The study used geographical and spatial information to identify potential sites for small scale hydropower projects. The study also considered several factors, such as the availability of water, the topography of the area, and the environmental impact of hydropower development. The study identified significant potential for small-scale hydropower development within the Vhembe District Municipality. It pinpointed several promising sites with minimal environmental impact. Developing small-scale hydropower in this area is presented as a viable option that could contribute to the local economy and South Africa's green energy transition. The study recommends that the Vhembe District Municipality further explore this potential and develop a plan for sustainable small-scale hydropower development in the region. These findings can inform similar projects in the region and beyond, becoming a valuable contribution to the national understanding of small-scale hydropower potential in South Africa.
