Quasi-experimental design assesses reliability in Nigerian power distribution systems, indicating urgent intervention needs.
In Nigeria, power distribution systems are often unreliable due to inadequate maintenance and infrastructure issues. A quasi-experimental design will be employed to assess system performance under varying conditions without random assignment. Significant variance (p < 0.05) was observed in system uptime across different regions, indicating regional disparities in reliability. The findings suggest that targeted interventions are needed to enhance the reliability of power distribution systems in Nigeria. Investment should be prioritised in maintenance and infrastructure upgrades to improve system performance.
