What the country might not be aware of is that 18 or so power stations that Eskom manages at the moment; there are five or six of them that over 40 years in age. They are old power stations; some of them are even 55 years of age. Hendrina Power Station for example, of the 10 units that were built in Hendrina, three of those units have already been shut down. Old age affects these power stations as well; it begins to affect the performance of these power stations and we have to deal with these challenges in addition.
