Power distribution equipment systems (PDES) play a critical role in agricultural productivity, particularly in Nigeria where they are essential for modernizing and optimising crop yields. However, their efficacy varies significantly across different regions due to varying environmental conditions and operational practices. A quasi-experimental design was employed, involving five distinct sites across Nigeria with varying climate zones. Data collection included pre- and post-intervention yields for comparison. Statistical analysis used linear regression models to assess the impact of PDES on crop output. The analysis revealed a 15% average increase in yield when PDES systems were operational, suggesting their significant contribution to agricultural productivity. However, variability was noted with some regions experiencing only 5-7% yield improvement due to local soil and climate conditions. This study provides evidence that PDES can substantially enhance crop yields under controlled conditions but requires tailored optimization for specific geographical areas. PDES systems should be adapted based on regional agricultural data to maximise their benefits. Future research could focus on long-term sustainability and cost-effectiveness of these systems in different climatic zones. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.
