Eskom has signed up 6,180MW of independently produced renewable power in its last 4 bid windows. It’s a 10th of Eskom’s generation capacity. But Eskom is only using a third of this renewable power, according to its daily generation reports. In November, Eskom used an average of 2,100MW of renewable energy. Eskom’s own wind farm generates 100MW.
To integrate new renewable energy generated in the Northern, Eastern, and Western Cape into the national grid, Eskom must add 14,218km of transmission lines by 2032. The deadline for this addition is 9 years away. Over the past 15 years, Eskom installed 7,200km of transmission lines at an average of 451km per year. To meet the 2032 deadline, Eskom will need to triple its efforts.
The Transmission Development Plan outlines two deadlines for Eskom: 2,893km of transmission lines installed by 2027 and 11,325km by 2032. These lines will extend the 350,000km-long national grid.
