Karpowership and REIPPPP BW7 capacity excluded in Eskom Medium-Term System Adequacy Outlook

  • The Medium-Term System Adequacy Outlook (MTSAO) assesses the ability of the electricity power system to meet demand within predefined adequacy thresholds in the next five calendar years.
  • The current study covers the calendar years 2024 to 2028 and is referred to as the MTSAO 2023.

Highlights include:

  • No coal power generation capacity will be decommissioned.
  • Energy demand growth uncertain.
  • Karpowership RMIPPPP projects excluded due to historic and current uncertainties with regard to progress with the projects.
  • The constrained transmission grid poses a risk in integrating new generation capacity. This will lead to a negative impact on system adequacy by delaying new generation projects or preventing them from being undertaken entirely. Eskom’s Grid Access Unit has already issued sufficient budget quotations to allow connection of private sector projects modelled in the MTSAO 2023 as a lever; however, the REIPPP Bid Window 7 projects remain at risk and have been modelled as such by reducing the new capacity by 5 000 MW.
  • Current projections indicate that commercial operation of Bid Window 5 projects is on track, bringing the total capacity to 7 499 MW by 2026 of renewables from the Independent Power Producer Programme.

  • Small-scale embedded generation (rooftop solar) a thumb suck at 880 MW per annum – due to the unavailability of centralised validated data, the extent to which rooftop PV is installed remains a challenge.

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.
