Solar continues to make inroads into Africa. For example construction recently started on a 600 MW solar plant in DRC.
Hopefully this massive 5,000 MW project gets broken into chunks and we see articles about 50MW solar plants under construction in the near future. Huge projects like this seem to have a tough time getting off the ground.
Currently Botswana and Namibia get most of their electricity from coal - including imports from unreliable South Africa.
Note: 6M in population between the two countries - so this is a LOT of solar.
