Eskom wind farm running at full capacity

Eskom wind farm running at full capacity

The Sere Wind Farm near Vredendal in the Western Cape has achieved its full operational capacity and is producing enough electricity to power 124,000 homes.

It contributes 100MW, but how reliable is it?
How many hours a day does it generate power?

Why is it so expensive to build wind farms? An equivalent to Medupi would cost R1.2 trillion.

Possibly as long as there is wind to drive it.

If you actually see just a single one of the blades for these things on the back of a VERY VERY VERY VERY long truck...then you'll immediately understand why.

35% capacity factor in average for onshore wind.

I have seen them while they were transported from Ngqura to Jeffreys bay. They aren’t that massive.
Isn’t it because they are imported by any chance?

Does the R1.2t include RSA bribes?
From what I've read wind power is cheapest when you factor in the health and CO2 emissions

The JBay ones are small. The blades are around 55m and the shaft 100m. They are made from a fiber glass polimer to shed weight and retain strength and are about 2m in diameter.

Compared to gas and coal.

What about hydro and nuclear who don't emit CO2 !

I took the build cost of R2.5 billion and multiplied by 48. The price tag for 100MW seems huge.

Wow, I didn’t know that there are larger ones.

Both will take a very long time to construct if I'm not mistaken. Those options, for me, are preferable to coal.

That's what SHE said.

Ha ha! Did you know you may not joke around in these threads?

 

[Voicy]

I did not.

Anyway, some are 140m tall with 63m blades.

 

[LaraC]

I did not.

I'm going totally off topic, but how do they fit so many blades on the turbine?

Edit: Never mind, I didn't see the "m" after the 63.

They aren’t that massive.

Aren't that massive?

They're freaking ginormous!

 

[Sinbad]

There is a farm coming on stream soonish in the northern cape made of over 125 turbines. Can't remember the power overall, but it's a lot!

So "Eskom wind farm" doesn't refer to Eskom's ever changing board of directors fartarsing about?
