The national grid experienced a system disturbance today, putting some parts of the country into darkness.
This is coming at a time when the Federal Government is celebrating what it called the historic rise in power generation to 6,000MW.
Report has it that power generation suddenly dropped below 1,000MW at 2 pm from about 4,000MW the hours before.
The peak generation for Friday was 5284MW at 5 am.
At 4 pm, generation was 803MW as many generation plants are yet to restore supply to the national grid.
The Transmission Company of Nigeria has yet to react to the incident.
