Power distribution equipment systems (PDES) play a crucial role in South Africa's energy infrastructure, yet their adoption rates and impact remain under-studied. The DiD model will utilise pre- and post-intervention data from various South African municipalities to assess changes in PDES adoption rates. Robust standard errors will be employed to account for potential confounding factors. A preliminary analysis suggests a significant increase in PDES adoption following the implementation of new distribution systems, with an estimated 20% rise compared to pre-intervention levels. The DiD model provides a robust framework for evaluating PDES effectiveness and can inform policy decisions aimed at enhancing energy accessibility and reliability. Future studies should consider extending the DiD analysis to other regions and sectors, as well as exploring potential synergies between PDES and renewable energy integration.
