develops when increasing levels of PV are added to the system. This phenomenon was first observed and published in a paper by. The phenomenon was then later confirmed in more detail by the California Independent System Operator in 2013. Since then , “shows the difference in electricity demand and the amount of available solar energy throughout the day. When the sun is shining, solar floods the market and then drops off as electricity demand peaks in the evening.
Meanwhile, on the other side of the world, South Africans have been ramping up installations of distributed solar in a big way to shield themselves from frequent electricity rationing cycles, and it seems that they have now installed a significant amount and we are starting to see the early signs of a prominent duck curve. Lets take a look as some of the key highlights of South Africa’s electricity landscape.South Africa has a nominal installed electricity generation capacity of 54.7 GW, 72.
Another nice chart from CRSES illustrates the tremendous growth in the distributed solar PV sector as homes and business rushed to install solar PV. South Africa’s national electricity utility company Eskom estimates that there is now over 5.4 GW of distributed solar PV installed in South Africa.This growth in distributed solar PV, plus the 2.
Solar PV systems, especially in homes, and now also increasingly in the C&I sector in South Africa, are usually coupled with lithium-based batteries systems as homes and businesses move to shield themselves from frequent electricity rationing cycles. The electricity situation has improved though over the past few months with very minimal to no load-shedding at all in South Africa.Hourly residual demand in South Africa, March from 2021 to 2024.

Remeredzai Joseph Kuhudzai has been fascinated with batteries since he was in primary school. As part of his High School Physics class he had to choose an elective course. He picked the renewable energy course and he has been hooked ever since.
