More problems at Koeberg

Koeberg's repaired generator one is faulty again, exposing the Western Cape to more power cuts. Eskom spokesperson Tony Stott says a faulty valve has caused the latest problems. He says the technical problem causes a shortage of 200 megawatts, which residents can save if they use electricity sparingly. Koeberg’s unit one became the Western Cape’s main electricity supplier since Monday when unit two was shut down for compulsory maintenance. But Stott says unit one’s output had to be cut to 80 percent in terms of safety requirements until the fault has been eliminated. Additional electricity is being fed in from Mpumalanga.
