According to industry records, this is the first of such low figures in about 12 years. This was contained in the records issued by the Federal Ministry of Power and the Independent System Operations (ISO) – the power grid managing section of the power sector – which revealed that between 2009 and 2021, the country recorded 259 cases of system disturbance. However, the trend which spreads outages that could last for a day or two nationwide or across half of the country dropped to just four in 2020, with just one incident so far in the first two months of 2021. Analysis of the records shows that 142 total and partial system collapses were recorded from 2009 to 2013.
