The Ghana Grid Company Limited GRIDCo says the nationwide power outages experienced in the early hours of Wednesday were caused by a disturbance on the National Interconnected Transmission System, which triggered the simultaneous shutdown of some power generation plants.

The company said its engineers and system operators immediately activated established system restoration procedures and were working with other power sector stakeholders to restore electricity in the shortest possible time without compromising safety.

GRIDCo said a comprehensive technical investigation had begun to determine the exact cause of the system disturbance.

GRDICo apologised to the public for the inconvenience and thanked customers for their patience and understanding during the restoration process.

The company said it remained committed to restoring power to all affected customers as quickly and safely as possible. It added that further updates would be provided as more information becomes available.
