Data from the Nigerian Electricity System Operator has revealed that power generation collapsed from 4,129.2 MW on Sunday to 2,441MW on Monday.
This may not be unconnected to the collapse of the national grid on Wednesday and Thursday last week, which reportedly led to power supply cut across many parts of the country.
In his reaction, Manager Director of the Transmission Company of Nigeria (TCN), Usman Mohammed had said a lack of spinning reserve which is meant to compensate for generation or transmission outages within 10 minutes, was responsible for the unending collapse.
He added that the installed generation capacity is 12,910.40MW; available capacity at 7,652.60MW; transmission wheeling capacity at 8,100MW; while the peak generation ever attained was 5,375MW.
Usman who spoke at a news conference in Abuja on Friday said, “Since I became the MD of TCN, the system instability recorded in the last two days (Wednesday and Thursday) was the worst because there was no time that we had system instability where the restoration took a longer time like this.
“And the reason is – we had a high voltage caused by the fact that electricity load was being rejected by the Discos. And the load was not being picked because of weak distribution network. So that is the reason for that instability”.
