South Africa to start building its largest solar power plant

Construction of South Africa’s largest renewable energy project to date – the Redstone concentrated solar power (CSP) plant – has commenced.

The R11.6 billion solar farm will be built about 30km east of Postmasburg in the Northern Cape and will have a generating output capacity of 100MW.

While this is less than the current largest solar power plant in South Africa – the De Aar project in the Northern Cape – it comes equipped with a 12-hour thermal storage system.

The price seems excessive. I thought plants that size cost R1 billion. :unsure:

This is Azania, everything is more expensive.

The overnight energy storage is where the costs are.
Note: FUEL is included in the R11.6b and maintenance is very low.

Medupi is 6*794MW = 4764MW
4764MW/100MW = 47.64 x R11.6b = ~R552b - probably less due to volume.

Medupi is at ~R150b >R234 billion (2019) and not finished.
See https://mybroadband.co.za/news/ener...-eskoms-medupi-and-kusile-power-stations.html

CSP seems expensive, until you realise the that Medupi does not include:
  • fuel costs
  • maintenance costs
  • pollution/environmental costs
I wonder if Solar Panel + Lithium Battery would be price competitive with with CSP?

I doubt. The energy density of Lithium Ion is actually quite low, and the cost quite high. Furthermore, there are technical limitations (e.g. Lithium Ion does not like to "deep cycle", loses capacity over time, fire hazard, etc.)

Ultimately a better solution is needed.

The 'Dark side of green energy' on Al Jazeera showed me that there are issues too with this kind of approach. Solutions will hopefully be found as we get further along the line.

World's biggest banana (looks like a giant battery)

Hornsdale Power Reserve - 193.5 MWh
