| Rank | Wind Farm | Installed Capacity (MW) | Context |
|---|---|---|---|
| 1 | Khobab + Loeriesfontein 2 | ~283 MW (combined) | These two sister farms form the largest contiguous facility. Khobab is ~140.3 MW, same for Loeriesfontein‑2. |
| 2 | Roggeveld | 147 MW | One of the larger single farms. |
| 3 | Soetwater | 147 MW | Enel Green Power project. |
| 4 | Garob | 145 MW | According to SAWEA listing. |
| 5 | Karusa | 140 MW | Listed in SAWEA report; part of newer capacity. |
| 6 | Oyster Bay | 140 MW | Also from SAWEA’s wind farm list. |
| 7 | Nxuba | 139 MW | According to SAWEA. |
| 8 | Cookhouse | 138.6 MW | Built by Suzlon; the capacity comes from SAWEA data. |
| 9 | Gouda Wind Farm | 138 MW | Listed in the SAWEA wind‑farm registry. |
| 10 | Jeffreys Bay Wind Farm | 138 MW | According to SAWEA’s list. |

Notable Emerging / Under‑Development Projects (2025)
- Wolf Wind Farm ~85 MW, under construction by Red Rocket in the Eastern Cape.
- New Bid-Window Projects — According to recent commentary, several REIPPPP projects are still coming online.
Analysis & Implications (Based on These 2025 Data)
- Scale Still Modest but Growing
- Despite more than 30 wind farms, the largest capacity per site is still around ~140‑150 MW, except for combined sites like Khobab + Loeriesfontein.
- Total installed wind capacity in the country is over 3.5 GW by March 2025.
- REIPPPP Impact Continues
- Many of the biggest farms (Karusa, Soetwater, Oyster Bay) trace back to REIPPPP bid windows.
- This suggests the procurement program remains central to wind capacity build-out.
- Geographic Clustering and Transmission Risk
- Several top farms are in the Northern Cape (Khobab, Loeriesfontein, Roggeveld), indicating resource-rich zones.
- But concentration in specific regions could pose transmission or grid-absorption challenges.
- Emerging Projects Signal Next Phase
- Wolf Wind (85 MW) is significant because it’s a new REIPPPP‑window addition, showing pipeline maturity.
- The fact that large capacity is still being added underscores wind’s role in future energy strategy.
Risks in This List
- Data Variability: Different sources report slightly different capacities (SAWEA’s list versus media).
- “Biggest” Ambiguity: Because some farms are considered in combined clusters (Khobab + Loeriesfontein), ranking by “single facility” can be subjective.
Operational vs Under Construction: Some capacity in SAWEA’s list is “in construction” or “contracted,” not fully operational.
