The Benin Electricity Distribution Company (BEDC) is used as a case study to analyse how privatisation affected the Nigerian economy. This study aims to determine how privatisation affected GDP growth in Nigeria, how privatised businesses fared in comparison to their public sector counterparts, and what obstacles were encountered along the privatisation process. A total of 400 participants, comprising employees of BEDC and electricity users in Delta State, were surveyed using a structured questionnaire as the main data collection tool in this descriptive survey study. The statistical methods used for data analysis included multiple regression, descriptive statistics, and SPSS-based Pearson correlation and analysis. According to the results, privatisation in Nigeria has a major effect on GDP growth, but it hasn't altered the efficiency of state enterprises much, and it hasn't presented any major obstacles either. The study's recommendations include an increase in investment infrastructure, a stronger regulatory oversight by the Federal Government through the Nigerian Electricity Regulatory Commission (NERC), and a higher priority for private firms to upgrade power distribution facilities like transformers, meters, and lines. Finally, BEDC and similar companies should adopt transparent operational and financial practice and accountability.
