Eskom Holdings, South Africa’s indebted power utility, is considering selling distribution assets as prospects of the government taking over about half of its R392-billion obligations dim, people with knowledge of the matter said. State-owned Eskom, which supplies almost all of South Africa’s power, has said that it needs to cut its borrowings to about 200 billion rand to be sustainable, and the idea of the government taking a chunk of the debt has been discussed for several years.
