According to the information received from Eskom
Eskom recognizes the negative impact that load shedding has on the lives of the people and the economy of South Africa. Eskom endeavours not to load shed and does so only as a last resort to ensure the security of the electricity network. However, Eskom’s generating fleet is ageing, at around 39 years on average, and it is both unreliable and unpredictable. As Eskom has often stated, until all the required reliability maintenance has been executed, all the new build units come on line and the DMRE emergency generation comes on line, the system remains constrained and the risk of load shedding remains high in the foreseeable future.
