On 2 April, a day with a reportedly elevated risk of load shedding, Eskom was able to provide 29.8GW of supply during the evening peak. But demand peaked at just under 31GW at around 6pm. The difference of more than 1GW was met using wind and concentrated solar power from IPPs.
Eskom used pumped water schemes and its hydro plants (total of 1.7GW), open cycle gas turbines (546MW) and demand-side management through its so-called “virtual power station” (409 MW) to achieve its nearly 30GW. Tellingly, it did not (have to) rely on either of the (very pricey) Avon or Dedisa gas peaking plants.
Wind comprised the bulk of the additional supply provided by the IPPs during the peak, with only a residual amount — easily less than 200MW — from concentrated solar.
Given the current dire performance from Eskom’s coal fleet, without renewable energy from the IPPs (at around 2GW), we would be in a near-perpetual state of stage-two load shedding.
