Abstract:
Uganda's industrialization efforts are driving significant demand for reliable and efficient power supply, particularly in the rapidly expanding industrial and commercial parks. While the country has a substantial installed power generation capacity of 1,237.49 MW, much of this remains underutilized due to inefficiencies in the power distribution network. This study evaluates the technical and commercial benefits of incorporating a 66 kV voltage level into Uganda's power distribution system, particularly for supplying large industrial loads. The analysis focuses on the advantages of higher distribution voltages in improving power transfer capacity, reducing technical losses, and optimizing the utilization of the country's electricity generation. Additionally, the study addresses the challenges posed by Uganda's anticipated load growth, which will require a significant expansion of substations and feeders, particularly in densely built industrial zones. By comparing the current 33 kV system with the proposed 66 kV upgrade, this study provides insights into how Uganda can better meet the increasing energy demands of its industrial sector, while minimizing losses and reducing electricity tariffs.
