On Wednesday, the national electricity grid collapsed, dropping power generation to about 260 megawatts (MW) and causing nationwide outage.
None of the over 20 generation Companies (GenCos) produced energy as of 1pm due to the system collapse while it was not immediately clear what caused the power grid disturbance, according to real-time power grid records by the Independent System Operations (ISO) section of the Transmission Company of Nigeria, TCN.
The peak power generation was 4,757MW as of Tuesday, while the lowest generation was 3,976MW. While 101,605 megawatts hour (MWH) energy was generated, consumers through the 11 Distribution Companies (DisCos) utilised 99,955MWH.
As of Tuesday, the peak power generation was 4,757MW while the lowest generation was 3,976MW. While 101,605 megawatts hour (MWH) energy was generated, consumers through the 11 Distribution Companies (DisCos) utilised 99,955MWH.
However, by Wednesday afternoon, checks indicated that only five of the 11 DisCos had slight energy allocation while the six others had no energy to supply to their customers across the states.
Their energy load expectations also dropped from over 4,000MW previously to 260MW by 1:00pm on Wednesday.
For instance, Abuja DisCo which had anticipated 458.927MW for Wednesday had it cut to 50MW by 1pm as efforts were ongoing to revive the national grid.
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.
