Majority of Nigerian cities have had electricity restored after experiencing total blackout on Sunday due to the national grid collapse.

Power generation fell to zero megawatts, causing widespread blackouts in major cities including the capital, Abuja.

Various electricity distribution companies across the country sent messages apologising to customers regarding the incident.

In a statement, Nigeria’s transmission company announced that the national grid has been restored after repairs were carried out.

This was the first grid collapse this year. It collapsed several times last year.

With an estimated population of more than 200 million, the country’s electricity generation still revolves between 3500 and 4500 megawatts.

Grid power supplies are often erratic in Nigeria despite its role as a major oil and gas producer.
