This study explores the significance of Management Information Systems (MIS) in securing a competitive edge for energy companies in Nigeria. In light of the increasing intricacies of operations within the energy sector, especially amidst a landscape characterised by digital transformation and international competition, Management Information Systems have become an essential strategic instrument. The study employs a secondary data approach, extracting insights from established literature, industry reports, and empirical studies to examine the role of Management Information Systems in enhancing cost efficiency, fostering innovation, improving customer service, and informing strategic decision-making. The findings indicate that although the adoption of Management Information Systems has resulted in notable enhancements in operational performance within technologically advanced energy firms, numerous organisations in the sector—particularly public and under-resourced entities—persist in encountering obstacles such as insufficient strategic alignment, inadequate digital infrastructure, and frail data governance. The research further highlights the significance of harmonising Management Information Systems with the overarching objectives of the organisation, while also underscoring the necessity for capacity enhancement and conducive governmental policies. The conclusion drawn is that the strategic implementation of Management Information Systems, coupled with institutional reforms, has the potential to serve as a significant catalyst for competitive advantage within Nigeria’s energy sector. Suggestions are put forth to bolster strategic alignment, refine digital infrastructure, and elevate data quality to fully leverage the advantages of Management Information Systems within the industry.
