This paper examines the challenge of epileptic electric power supply in Nigeria since independence till date. The paper observes that a majority of Nigerians now pay excessively for darkness as they experience power outage for an average of 20 hours daily, while their estimated billing has continued to increase astronomically, unabated. This has impacted negatively on the socio-economic development of the country and is currently inciting conflicts between the electricity distribution companies and aggrieved consumers across the country. In view of the above, the paper identified some factors responsible for this ugly development and highlights some of its effects on Nigeria's economy. Data for the study was obtained through oral interviews with electricity consumers (especially in Ekiti, Osun and Oyo states) and officials of Ibadan and Benin Electricity Distribution Companies; personal observations; group discussion method; and a rigorous library search of related literature. The study employed the descriptive and analytical qualitative methods of historical research to analyse its data. It recommends that electricity supply should be given necessary attention by the government to enable the country harness her rich human and material resources.
