Quality, reliable and affordable power, is clearly sufficient as a social-economic catalyst to propel any nation's shrinking economy, increase jobs creation and reduce crime. This can be guaranteed if the power grid is stable. Grid collapse occur when the supply of electricity to some or entire regions is disrupted. Despite significant investments in the sector over the last two decades, the Nigerian electrical grid continues to be unreliable, experiencing random failures. Between 2000 and 2022, it has partially or completely collapsed 564 times, and the frequency of such incidents per year is a cause for concern. The incidents practically grounded Nigeria and its economic activity on each occasion. As a result, it is no surprise that the economy is tanking and businesses are closing up. This study identifies the limiting variables that have hampered the electricity system's viability, among which are human factors, equipment failure as a result of aging, fuel shortage and sabotage, likewise poor maintenance of transmission infrastructure. These had adverse effect on the productivity of the nation. The report also suggests mitigating strategies for avoiding blackouts in the future, include but not limit to regular proactive inspection, testing, repair of the equipment, adoption of real-time monitoring, and control system to improve grid resilience and promote grid efficiency management.
