Stage 3 blackouts resume in South Africa after nine days of no blackouts

  • South Africa’s state owned and state run energy utility, Eskom, reports that after nine days of good generation performance and no loadshedding, it is necessary to replenish emergency reserves ahead of the anticipated cold weather that will increase the demand for electricity over the next few days.
  • As such Stage 2 loadshedding will be implemented from 16:00 today until 16:00 on Monday.
  • Thereafter, Stage 3 loadshedding will be implemented from 16:00 until 05:00 on Tuesday, followed by Stage 2 loadshedding until 16:00.
  • This pattern will be repeated daily until further notice.

Breakdowns are currently at 16 150MW of generating capacity while the capacity out of service for planned maintenance is 5 950MW. Over the past 24 hours, a generation unit each at Duvha, Grootvlei, Kusile and Matimba power stations was taken offline for repairs. In the same period, a generation unit at Kriel Power Station was returned to service.

Respected energy analyse, Chris Yelland- CEO, EE Business Intelligence, reports on his X feed that Eskom week-on-week energy availability factor (EAF) has broken the 60% barrier, reaching 60.46% in Week 42, 2023. This reverses the usual declining trend and is largely due to three 800MW generation units returning to service at Kusile coal fired power station after temporary repairs were carried out.  The units have been returned to service after Eskom was granted permission to bypass the plant’s Flue Gas Desulphurization equipment and emit unabated sulphur dioxide (SO2) and increased mercury emissions.

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
