Hydropower remains one of the most significant renewable energy sources, accounting for a substantial proportion of global electricity production. In Tanzania, where electricity access is limited, particularly in rural areas, untapped hydropower resources could play a critical role in meeting local energy needs. This study investigates the hydropower potential of the Kapologwe Waterfalls on the Kala River, located in Rungwe District, Mbeya Region. Key factors influencing hydropower generation, including hydraulic head, flow rate, and turbine efficiency, were analyzed using land survey techniques and hydrological modeling. The hydraulic head was measured at 605.15 meters, and flow rates were calculated based on field data, with a design flow of 1.542 m³/s. A Pelton turbine, known for its high efficiency under high-head, low-flow conditions, was selected for the site. The estimated power potential is 7.238 MW, suggesting that the Kapologwe Waterfalls could significantly contribute to localized electrification and reduce reliance on Tanzania’s national grid. This research highlights the feasibility of small-scale hydropower projects in rural Tanzania and their potential to alleviate energy poverty.
