The Ghana Grid Company Limited (GRIDCo) says the widespread power outage experienced across parts of the country, was caused by a disturbance on the National Interconnected Transmission System.
According to the company, this power system disturbance occurred in the early hours of Wednesday, July 29, 2026, at approximately 3:11 a.m.
This, it noted, resulted in the “simultaneous tripping of some generating plants across the national power system, leading to interruption of electricity supply.”
GRIDCo said it has activated its established system restoration procedures.
“Our engineers and system operators are working continuously, in close collaboration with power sector stakeholders, to restore power within the shortest time possible without compromising safety,” the company said in a statement.
GRIDCo also announced that a comprehensive technical investigation has begun to determine the exact cause of the system disturbance.
The company apologised for the inconvenience caused and expressed appreciation to the public for their patience and understanding during the restoration process.
GRIDCo assured customers that it remains committed to restoring power supply to all affected areas safely and promptly.
“We remain fully committed to restoring supply to all affected customers as quickly and safely as possible and will provide further updates as more information becomes available.”
