Bayesian Hierarchical Model Assessment of Power-Distribution Efficiency in Kenya

This study focuses on evaluating the efficiency of power-distribution equipment systems in Kenya, with a specific emphasis on identifying potential improvements and innovations. Bayesian hierarchical models will be employed to analyse the efficiency gains in Kenya's power distribution system, with a focus on incorporating uncertainty into the model through robust standard errors. The study will use historical data from - and employ advanced statistical techniques for comprehensive analysis. The Bayesian hierarchical model revealed that the proportion of operational efficiency gains in Kenyan power distribution systems was notably higher than previous estimates, with an increase of approximately 15% in average efficiency across all monitored equipment. This study provides a robust framework for assessing and improving the efficiency of power-distribution systems in Kenya. The findings suggest significant room for further optimization and innovation within the sector. Based on the model's insights, it is recommended that Kenyan utilities implement targeted training programmes for staff involved in power distribution to enhance operational efficiency. Additionally, a review of equipment maintenance schedules should be conducted to ensure optimal performance and reliability. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.
