Analyzing Distribution Network Performance Gaps and Modernization Challenges in Uganda’s Electricity Sector: A Case Study of Kampala West Region

Abstract

This paper analyzes Uganda’s electricity distribution network performance gaps and modernization challenges using Kampala West region’s Kitala feeder as a case study. Industry-standard reliability indices including System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), Customer Average Interruption Duration Index (CAIDI), modernization maturity assessment, and network simulations identified high outage durations, frequent interruptions, and significant feeder losses. Modernization interventions including protection coordination, network reconfiguration, reconductoring, parallel circuits, and distributed generation significantly improved reliability and reduced losses. Cost-benefit analysis using Net Present Value (NPV) and payback period metrics highlighted the most economically viable interventions. The study recommends targeted interventions with optimal NPV and payback period values, replicable to similar urban feeders across Sub-Saharan Africa. Policy formulation and regulations supporting comprehensive distribution network modernization are essential to achieve reliable electricity supply and supportUganda’s Vision 2040 goals.
