JOHANNESBURG - Unit 5 of Kusile Power Station has been synchronised.
It is expected to contribute an extra 800 megawatts to the national grid.
Koeberg's Unit 1 has completed a full load rejection test, which is the final step to ensuring that it regains its generative power.
However, despite the power utility making significant progress in boosting generation capacity, Eskom has announced the return of blackouts after a brief reprieve during the festive season.
