RAY SMUTS THE recent arrival in Cape Town of a 200-ton rotor for Koeberg nuclear power station - supplier of only half of the Western Cape’s power requirements - by no means signifies the end of potential headaches for commerce, industry and domestic consumers alike. What is as certain as dawn tomorrow is that further power outages, which have already cost the province billions of rand in lost production, are inevitable for another four months at least, at a time power demands will be greatly exacerbated due to the coming winter. The second-hand rotor, on loan from French power utility, Electricite de France, was brought to Cape Town from Antwerp by the South African naval supply ship SAS Drakensberg. It was packed in a coffin-shaped box, shackled down to one of the helicopter flight decks.
