Abstract
Power distribution equipment (PDE) systems are critical for reliable electricity supply in Tanzania. Despite their importance, adoption rates of these systems vary significantly across different regions and communities. A mixed-methods approach was employed, including surveys and interviews. Quasi-experimental techniques were used to assess the impact of these systems without random assignment. In one specific district, we observed a 30% higher adoption rate in communities where PDE systems were installed compared to those who did not receive them (95% CI: 12-48%). The quasi-experimental design successfully identified significant differences in adoption rates between treatment and control groups. Further research should be conducted to explore the long-term effects of PDE systems on community electricity access, with a focus on improving accessibility for underprivileged areas.
