What is System Management?

Eskom currently finds itself in a position where the demand for electricity may exceed the available supply from time to time. In order to manage the situation in the best possible way, planned supply interruptions may have to be carried out. Customers who receive their electricity directly from Eskom will find information of possible outages on this website. Those who are supplied by their local municipalities, however, will have to obtain load shedding information from the municipal electricity departments.

What is system management?

When there is not enough electricity available to meet the demand from all Eskom's customers, it could be necessary to interrupt supply to certain areas. This is called System Management.

System management is:

  • A last resort measure. Only when all other options at its disposal have been exhausted, such as running its power stations at maximum capacity and interrupting supply to industrial customers with special contracts, will Eskom cut supply to other customers.

  • A controlled way of rotating the available electricity between all customers. System Management schedules are drawn up to ensure that a few areas do not bear the brunt of the shortages. By spreading the impact, affected areas are not interrupted for more than two hours at a time, and in most cases customers can be informed of interruptions in advance.

  • An effective way to avoid blackouts. Shortages on the electricity system unbalance the network, which can cause it to collapse. By rotating the load in a planned and controlled manner, the system remains stable.
