The power distribution sector in Nigeria faces significant challenges related to equipment quality, efficiency, and reliability. A mixed-method approach combining quantitative analysis with qualitative insights was employed. Panel data from multiple years were analysed using a fixed-effects regression model to estimate adoption rates. Panel data revealed that the installation of high-efficiency transformers led to an increase in power distribution efficiency by 15% compared to conventional equipment, as measured over three years. The study provides evidence on the effectiveness of certain power-distribution systems and offers a robust method for analysing adoption rates across different regions in Nigeria. Future research should consider longitudinal studies with additional variables to enhance the predictive accuracy of the models used.
