JOHANNESBURG - When the lights go off and you can&39;t cook or watch TV, we know that it&39;s Eskom load-shedding, but what do these two words really mean?

On Monday afternoon Eskom CEO Tshediso Matona addressed the nation on reasons why the power utility has resorted to load-shedding. He said the blackouts were set to continue.

“I would like to start out by apologising for all the inconvenience,” Matona said, referring to massive load-shedding that happened on Thursday last week and the downscaling to Stage 3 on Friday afternoon.

Matona said load-shedding was necessitated because South Africa was facing a looming national blackout with the whole system tripping due to demand exceeding supply.

This week the country was facing Stage 3 load-shedding, which meant power cuts happen twice a day with 90 percent of the country’s demand being met.

The power system would remain severely constrained for the next 12 to 18 months.
