Power distribution equipment (PDE) efficiency is crucial for ensuring reliable electricity supply in Ghanaian infrastructure. A multilevel regression model was applied to analyse the efficiency of power distribution equipment across different geographical regions and utilities. Data on operational metrics were collected from a sample of PDE units in Ghana. The analysis revealed significant variations in PDE performance, with certain regions showing efficiency gains up to 20% when infrastructure improvements are implemented. This study underscores the importance of targeted interventions for enhancing PDE efficiency and reliability. Future research should explore longer-term impacts and scalability of these findings. Utility companies in Ghana should prioritise investment in modernizing PDE systems, particularly in underserved regions to achieve equitable electricity access.
