This study focuses on evaluating power-distribution equipment systems in Nigeria, a country with significant infrastructure challenges. A multilevel regression model was employed to analyse data collected from multiple power distribution points across different regions in Nigeria. Data revealed a 15% yield improvement potential when considering regional variations, indicating significant opportunities for enhancement. The findings suggest that optimising power distribution systems can lead to substantial improvements in efficiency and reliability. Implementing targeted upgrades at key nodes could significantly boost overall system performance. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
