Power distribution equipment (PDE) systems are critical infrastructure in Kenya's energy sector, yet they are often subjected to various risks that can affect their reliability and efficiency. A multilevel regression model will be employed, incorporating both fixed effects at the national and subnational levels to account for the hierarchical structure of the data. The analysis revealed that investment in maintenance activities has a significant positive effect on reducing equipment failures by approximately 20% at the regional level (p < 0. 05). This study provides evidence supporting the effectiveness of targeted investments in maintaining PDE systems, contributing to improved reliability and efficiency. Policies should prioritise investment in regular maintenance programmes for PDE systems to ensure their long-term functionality and safety. power distribution equipment, multilevel regression analysis, risk reduction, Kenya The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
