South Africa boasts 34 operational wind farms, predominantly owned by Unbiased Energy Producers (IPPs), contributing over 3,400MW to the nation’s electrical energy grid. Essentially the most substantial wind energy facility contains Khobab and Loeriesfontein 2 farms, that includes 122 generators with a most capability of round 283MW. These wind farms are primarily concentrated within the Cape provinces as a consequence of their beneficial wind circumstances and talent to provide electrical energy throughout peak demand hours. Regardless of their intermittent effectivity (sometimes 30-45% of capability), wind farms play an important position in diversifying South Africa’s vitality combine. Nonetheless, the nation faces transmission capability challenges in these areas, necessitating vital investments to accommodate extra renewable energy sources sooner or later, with a number of new wind farm tasks within the pipeline.

All 34 wind farms offering energy to South Africa
By Hanno Labuschagne
There are at the moment 34 operational wind farms including a mixed capability of greater than 3,400MW to South Africa’s electrical energy grid, in response to the Division of Power’s IPP Tasks web site and official Eskom information.
Unbiased Energy Producers (IPPs) personal all however certainly one of these services. These IPPs, in flip, promote their electrical energy to Eskom.
The one Eskom-owned wind energy station is the Sere Wind Farm close to Vredendal within the Western Cape, which contributes roughly 105MW.
Wind farms include quite a few generators with three massive blades turned by wind.

The generators are related to a drive shaft which turns an electrical generator to provide electrical energy.
Every wind farm can have tens and even a whole lot of generators with outputs sometimes round 2–3 MW every.
The most important wind energy facility within the nation is definitely two adjoining farms — Khobab and Loeriesfontein 2 within the Northern Cape.
These two farms have 122 Siemens SWT-2.3-108 generators between them, offering a most producing capability of roughly 283MW.
The generators on these farms stand 152 metres tall when measured from the bottom to the tip of their blades on the highest rotation level.
There are a number of different massive wind farms in South Africa with capacities between 135MW and 140MW.
In response to Eskom’s information, the mixed capability of the wind farms related to its grid is 3,443MW, whereas the Division of Power’s listing exhibits it being nearer to three,309MW.
The discrepancy is perhaps as a consequence of further capability coming on-line at some wind farms that weren’t up to date on the division’s database.
Assuming the mixed capability is 3,443MW, and every turbine contributes roughly 2–3MW, there may very well be wherever between 1,148 and 1,722 generators within the nation.
Concentrated within the Cape
All wind farms offering energy to Eskom’s grid are situated within the Cape provinces, that are typically extra windy than different places within the nation.
The Northern Cape’s dry and sunny climate additionally makes it engaging for solar energy stations.
Wind farms have one main benefit over solar energy — they’ll present energy at evening, together with throughout the night peak electrical energy demand intervals that put a pressure on Eskom’s coal fleet.

For giant-scale installations, wind energy additionally works out to be less expensive than massive photo voltaic farms. The latter is good for smaller installations nearer to the focused buyer — like on a rooftop.
In response to EDF Power, wind farms function at a median effectivity between 30–45% of their nameplate capability.
Nonetheless, they’ll contribute way more than this at sure instances, as proven in Eskom’s publicly accessible renewable technology information portal.
The best quantity of wind energy contributed throughout 2023 was 3,102.2MW, roughly 90% of the entire put in capability.
Sadly, the excessive focus of renewable energy stations within the Cape provinces has led to Eskom working out of transmission capability on this a part of the nation.
In 2022, not a single further megawatt of wind capability was added to the grid as a consequence of this limitation.
Eskom desperately must develop its transmission community — which it estimates will price R210 billion — to allow extra permitted renewable IPPs to ultimately connect with the nationwide energy grid.

It’s hoped that spinning off Eskom’s transmission division right into a separate firm will assist unlock the mandatory funding to make this doable.
In response to the vitality division’s IPP database, seven further wind farms are at the moment underneath development within the Cape provinces, which is able to present an additional 780MW of capability.
One other six wind farm tasks are but to achieve monetary shut. In the event that they succeed, they are going to add one other 824MW as soon as operational.
The desk under summarises the places and capacities of all of South Africa’s wind farms offering energy to the nationwide grid.
