Flights have resumed operations at Cape Town International Airport following a power outage that disrupted services on Sunday. An investigation is currently underway to ascertain the cause of the incident.

On Sunday evening, operations at the airport were halted for several hours, preventing flights from landing or taking off due to a power supply failure that impacted runway lighting, airside fire rescue, and air traffic control services.

Airports Company South Africa (Acsa) announced at 1 a.m. on Monday that the runway lighting and navigational systems had been restored, enabling 11 aircraft to successfully land at the airport.

Ernest Mulibana, a corporate communication strategist at Acsa, later confirmed on Monday that conditions at the airport had improved considerably, with flights now able to land and depart, although some technical issues were still being addressed.

A team of technicians and experts is investigating the cause of the outage while working on permanent repairs and the restoration of the airport's network.

"The objective is to resolve this issue as swiftly as possible, as we are operating within a timeline, and we are still in the process of determining the exact cause," stated Mulibana.

Mulibana was unable to provide the precise number of flights that were delayed or canceled. He mentioned that United Airlines, Delta, and South African Airways flights successfully took off after the runway lights and navigational aids were restored.

Travelers are advised to download the Acsa mobile app for real-time flight updates and to stay in touch with their respective airlines for the latest information.

According to a report by Daily Maverick on Monday, FlySafair stated in a travel update that their operations center was informed of a power outage at Cape Town International Airport around 8:30 pm on Sunday.

The airline stated that they are currently in discussions with Acsa to determine the cause and expected duration of the outage, emphasizing that all airlines operating to and from the airport are affected.

The airline announced on Monday that flights were disrupted due to an outage, resulting in the inability of flights to take off or land. This caused significant operational disruptions for multiple airlines. A total of eleven FlySafair flights were impacted.

Six flights that were already in the air when the power failure occurred were redirected to Port Elizabeth, two flights were redirected to Johannesburg, and the rest were grounded. The sudden increase in flights to Port Elizabeth, a location not typically prepared to handle such a large volume of aircraft and passengers, presented a major logistical challenge.

Despite these obstacles, our teams worked diligently to handle the situation and offer support to affected passengers.
