KEY POINTS
- Eskom says no load shedding is expected after a transmission fault reduced output at Koeberg.
- Both nuclear units were safely scaled down as a precaution, with reactors unaffected.
- Authorities have approved a gradual return to full power under strict safety protocols.
Eskom says that South Africans shouldn’t expect load shedding after a transmission problem caused a temporary drop in power output at the Koeberg Nuclear Power Station.
The utility took steps to calm fears after both Koeberg units were automatically turned down on Tuesday because of a problem with the 132kV transmission lines that connect to the Pinotage substation in the Western Cape.
The power utility confirmed that the National Nuclear Regulator was informed of the incident as required under safety and regulatory protocols.
Eskom said South Africa has enough generation reserves to absorb the temporary loss of output, meaning there is no risk of load shedding as a result of the incident.
Gradual return to full power underway
Eskom also disclosed that the National Transmission Company has approved the gradual ramping up of both Koeberg units back to full power. The process, it said, is being carried out cautiously and in strict compliance with all safety and regulatory requirements.
The utility reiterated its commitment to maintaining the stability of the power system while ensuring that nuclear safety standards remain fully intact.
Koeberg is Africa’s only nuclear power station and plays a critical role in South Africa’s electricity supply, contributing about 1,860 megawatts at full capacity. It is a key source of baseload power for the Western Cape and the national grid.
Eskom reiterated its commitment to maintaining reliable electricity supply while prioritising safety, particularly at strategic generation assets such as Koeberg.
