The entire country was once again plunged into total darkness last night following another nationwide blackout, the third such incident this year. The blackout which hit at about 7pm lasted for nearly four hours and even longer in some other parts of the country. Disenchanted customers of the utility company who had access to the social media expressed outrage on the internet. Unlike the previous incidents this year, the Ghana Grid Company says it is yet to establish the cause of the problem. The Head of Public Relations of GRIDCO, Mr Albert Kwesi Quainoo told Joy News the company’s technical team will meet to commence investigations. He said staff of the company rallied to restore power to consumers. The nationwide power outage meanwhile comes at a time electricity consumers are being told a load-shedding exercise thought to have been suspended after a month would last a while longer. Officials at the Electricity Company of Ghana tell Joy News they have also been experiencing a number of hitches which have compounded the supply shortfall prompted by the gas supply problems in Nigeria. The authorities in Nigeria say the supply shortfall will be adequately addressed within two months.
