Shortage of gas has hit at least 16 power generating plants causing power generation at its highest point to drop to 3,922 megawatts (MW) on Saturday.
Operators said the drop would continue for another 10 days (since Friday) until scheduled maintenance was completed on the gas pipelines.
Daily power generation statistics obtained by Daily Trust from the Independent System Operator (ISO), a section of the Transmission Company of Nigeria (TCN), puts peak generation at 4,055MW on Friday, but dropped to 3,922MW at the close of that day. By Saturday, the peak generation had dropped to 3,675MW.
The highest power generation recorded on Sunday was 3,660MW, falling off the 4,000MW threshold recorded on Friday.
