EVALUATING THE EFFICIENCY OF NIGERIA'S POWER SECTOR PRIVATIZATION: A COMPARATIVE ANALYSIS OF PRE- AND POST-PRIVATIZATION PERFORMANCE METRICS

Abstract

Reliable electricity supply is essential for economic growth and national development, yet Nigeria’s power sector has historically experienced persistent inefficiencies and inadequate electricity supply. In response to these challenges, the Nigerian government implemented power sector reforms that culminated in the privatization of electricity generation and distribution companies in 2013. This study evaluated the efficiency of Nigeria’s power sector privatization through a comparative analysis of pre- and post-privatization performance indicators. The study adopted a comparative quantitative research design and relied on secondary data obtained from institutional sources including regulatory and government reports. Key performance indicators examined included electricity generation capacity, electricity distribution efficiency, and overall operational performance of the sector. Descriptive statistics and paired sample t-test were used to analyze the data at a 0.05 level of significance. The findings revealed that electricity generation capacity improved moderately after privatization and that a statistically significant difference existed between the pre-privatization and post-privatization periods. The study also found that electricity distribution efficiency and service delivery improved significantly in the post-privatization era. In addition, the overall operational performance of the Nigerian power sector showed a statistically significant improvement following the reform. Despite these improvements, the findings indicated that the gains achieved remain moderate due to persistent structural and infrastructural challenges within the electricity value chain. The study therefore concludes that while privatization has contributed to some improvements in sector performance, additional policy interventions and infrastructural investments are necessary to achieve sustainable electricity supply in Nigeria.
