摘要:Efficient and effective electricity generation, transmission and distribution are critical to national development in both developed and developing societies. This study examines the constraining role of the prevailing discriminatory monopolistic environment in the actualization of adequate and sustained power supply in Nigeria. The data utilized in this study were derived from both primary and secondary sources. While the primary data were obtained from focused group discussions, the secondary data were sourced from relevant text books, journals and available statistics on electricity generation and supply in Nigeria. The findings of the study reveals that the discriminatory monopolistic environment typified by near absence of competition and poor service culture have severely constrained the much-desired adequate electricity generation capacity and effective service delivery in Nigeria. Finally, the study recommends among others that the Power Holding Company of Nigeria should operate in a competitive industrial environment where there exists a service culture.
