The supply of stable power supply of electricity to consumers is the backbone of socio- economic growth of any nation and Nigeria is not an exception. The Power sector in Nigeria has multidimensional problems such as: use of overloaded power transformers in the grid substation, Altitude of top Management, Government altitude and contractors’ altitude toward power generation, corruption and mismanagement of funds. These factors affects the performance indices (efficiency, number of consumers connected to distribution line per unit transformer, transmission losses and maintenance cost) of electricity utilities in the country. Electric power is the engine that drives industrialization, which improves communication, helps innovation in science and Technology, provides sound healthcare delivery system and improve citizens standard of living. The review revealed that the total grid capacity of 7,139.60 MW with 3,572.6 MW (peak generation), 3,091.8 MW (lowest generation), 80,308.49 MWH (energy recorded), 49.232 Hz (lowest system frequency), 51.18 Hz (highest system frequency), 347 Kv (highest voltage recorded), 300 Kv (lowest voltage recorded) as at February 18, 2015 and 3,490.7 MW (generation at 06:00 Hrs) as at February 19, 2015. Hence, this paper investigated into the causes of unstable power supply of electricity in Nigeria and proffers solutions to the problem. One of the solution proffers in this paper is the use of alternative means of generation which will go a long way in solving stability of electric power problem in Nigeria. Aim of this paper is to ensure efficient, safe and adequate production of electricity, evolve stable and equitable rates thereby ensuring reasonably profits in power sector.
