The power supplier says in a release that although there has been a slight improvement in generation performance, they have unfortunately had further breakdowns at Kusile, Matla, and Tutuka Power Stations. This means Eskom has to implement stage 3 load-shedding from 08:00 until 22:00 on Thursday. 

Eskom says this is in order to continue replenishing the emergency generation reserves, which have been depleted. These emergency reserves are required to respond to emergencies in order to maintain the stability of the national grid. 

Thereafter stage 2 load-shedding will be implemented as previously communicated.
 
According to the release, breakdowns currently total 13 995MW of capacity, while planned maintenance is 1 273MW of capacity.
 
These capacity constraints will continue for the foreseeable future and all South Africans are urged to reduce their use of electricity.
