This study meticulously examines the impacts of attacks and vandalism on Nigerian electricity transmission lines, analysing their causes, consequences, and potential mitigation strategies. Historical data reveals that socio- economic and political factors are the root causes of these destructive acts, including insurgencies and economic desperation. Recent trends show an alarming increase in the frequency and sophistication of such attacks, primarily using explosives, which pose a significant challenge to the Nigerian electricity sector. The geographical distribution of these incidents is a cause for concern, with a concentration in the Northeast and North-Central regions directly correlating with regional instability. The severe economic and social impacts are leading to prolonged power outages, substantial financial losses, and public dissatisfaction. This paper underscores the potential of a multi-faceted approach, including enhanced security measures, community engagement, and strategic policy reforms, to protect vital infrastructure and ensure a stable electricity supply. The research findings are a call to action for policymakers and stakeholders, providing a solid foundation for enhancing the resilience and reliability of Nigeria's power transmission system. Our collective responsibility is to act on these findings and contribute to the solution.
