State-owned utility Eskom was forced to implement Stage 4 load-shedding on the evening of May 16 after Unit 2 at the Kusile power station tripped, Eskom spokesperson Sikonathi Mantshantsha said. The tripped Kusile unit removed 720 MW of generating capacity from the already constrained grid.
Load-shedding will be escalated to Stage 4 on Monday afternoon, Eskom announced. This is owing to a unit at Kusile power station tripping earlier on Monday, taking 720MW of generating capacity with it, Eskom spokesperson Sikonathi Mantshantsha said.  “While this unit has since returned to service, it will slowly load up to full capacity during the night.” 
South Africa will eventually find itself with a thoroughly modern electricity supply sector, including many generators competing with each other, an effective distribution operator and a wide marketplace for consumers to buy electricity.

Businesses should see through the doom and gloom of the current electricity mess and plan for the brighter future on the horizon, Business Leadership South Africa CEO Busi Mavuso suggests in her latest weekly newsletter, while also asking whether business is ready for an electricity system that works.
