The Ghana Grid Company has attributed the nationwide blackout that hit the country Thursday night to a fault in one of   the country's transmission lines.

Chief Executive Officer of the Ghana Grid Company, William Amuna, in an interview on the CITI Breakfast show allayed fears that the country's energy crisis was back.

" The blackout was due to a disturbance in one of our transmission lines, leading to massive blackout in Accra, Tema and other parts of the country, it is not a generation issue as was the case during the country's energy crises."

Mr. Amuna disputed assertions that the blackout occurred nationwide.

" No, no, that's not true. It wasn't 90 percent of the country. We had 40 to 60 percent of the country on. The whole of the Western Region for example was on. It was some parts of the country, and as we speak we have restored 90 percent of the affected parts."

Meanwhile, The power transmitting company will have to do more investigations in the cause of the disturbance to the major transmission line, Mr. Amuna said. He however assured that this was a rare occurrence.

" More investigations will be done to ascertain what exactly caused the problem. But I can assure you you that this is a rare occurrence. The last time this happened was in 2010."
