The entire oil city was thrown into darkness a few minutes after the flagbearer of the National Democratic Congress, John Dramani Mahama started his presentation of the manifesto.
It was an unannounced power outage, and no explanation has been given yet regard the cause.
Earlier this morning the Electricity Company of Ghana announced of a planned power outage in parts of the Ahanta West Municipality.
The situation has left some residents to speculate it was intended to deny people an opportunity to watch the most anticipated launch of the NDC Manifesto.
