Power-distribution equipment systems (PDES) play a critical role in ensuring efficient power supply to rural and remote areas of Ghana. However, their effectiveness is often underpinned by empirical evidence. A randomized field trial was conducted across three regions in Ghana with a sample size of 120 villages. The study used a linear regression model to assess the impact of PDES on agricultural output, accounting for potential confounders such as climate and soil type. The analysis revealed that the introduction of PDES led to an average yield improvement of 15% in targeted crops across the regions studied. This finding supports the hypothesis that improved power distribution enhances agricultural productivity. This study provides a robust methodological framework for evaluating PDES in Ghana, offering insights into how such systems can be optimised for future applications. Future research should explore the long-term sustainability of these methods and investigate potential synergies between improved PDES and other agricultural interventions. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
