Eskom has raised R76.1-million from the sale of two buildings as parts of a strategy to free up cash through the disposal on non-core assets, and more properties are expected to be sold. The buildings in Kimberley and Johannesburg were sold to the Department of Human Settlements, Water and Sanitation and will be converted into housing blocks, the power utility announced on Tuesday. Eskom, which is saddled with nearly half a trillion rand in debt, boasts an extensive portfolio of properties plans to raise more than R2-billion from the sale of non-core property.
