There was an enormous summit for the Southern African Growth Neighborhood (SADC) over the previous weekend in Harare, Zimbabwe. It was the 44th version of this summit, with heads of state for 13 out of the 16 member states attending.

The SADC web site states “The mission of SADC is to advertise sustainable and equitable financial development and socio-economic growth by way of environment friendly, productive methods, deeper cooperation and integration, good governance and sturdy peace and safety; in order that the area emerges as a aggressive and efficient participant in worldwide relations and the world financial system.”

This imaginative and prescient of sustainable and equitable financial development will likely be hampered by the area’s dire electrical energy scenario. In Half 2 of this collection, we are going to check out the present state of electrical energy provide for these residents which can be related to the respective member states’ nationwide grids. Right here we are going to deal with numerous nations that face perennial electrical energy rationing, infamously often called load-shedding. For a have a look at the present stage of entry to electrical energy, or reasonably a have a look at the proportion of residents that aren’t related to the nationwide grids of SADC member States, you will discover Half 1 of this collection right here.

12 nations in Southern Africa are a part of the Southern African Energy Pool (SAPP). The SAPP is essentially the most lively energy pool in Africa. The entire put in technology capability within the area is 80 GW. The height demand within the area is 57 GW, nonetheless, the obtainable capability is simply 48 GW in line with the figures from the SAPP, leaving an enormous electrical energy technology shortfall. Absolutely which means there ought to be some urgency round fixing this huge technology shortfall.

Probably the most affected member states are South Africa, Zambia, and Zimbabwe, the place residents face common electrical energy rationing cycles often called load-shedding. The electrical energy technology combine within the Southern African Energy Pool is dominated by coal. Coal’s share is at 59% (principally from South Africa and locations like Zimbabwe), adopted by hydro at 24%, photo voltaic PV at 4%, distillate at 3.8%,  then wind and nuclear (South Africa) at 3%, and open cycle fuel generators at 2%.

9 nations are at the moment interconnected on the transmission stage, with 3 nations not but related to the SAPP grid. Malawi is related by way of the Mozambique – Malawi Interconnector and Tanzania is being related by way of the Zambia – Tanzania Interconnector, which is able to result in interconnection of SAPP and the East African Energy Pool as Tanzania can be being related to Kenya. Angola will likely be related to Namibia, DRC, and Zambia.

A have a look at the technology and demand knowledge exhibits that there’s an pressing must speed up new interconnections in addition to develop present interconnection capability to facilitate enlargement of regional commerce. There are some plans round this, and one would suppose these ought to be larger up the agenda for these sorts of summits, nevertheless it doesn’t appear to be the case.

The persistent load-shedding points plaguing South Africa, Zambia, and Zimbabwe may very well be solved by unlocking the complete potential of the Southern African Energy Pool in addition to the East African Energy Pool as soon as it’s absolutely activated. That is why it’s vital to prioritize and speed up deliberate interconnections between Tanzania and Zambia in addition to Angola’s to Namibia, DRC, and Zambia.

Taking a look at desk beneath from SAPP, Angola had an extra capability of round 2.4 GW. A few of this may very well be taken up by different members of the SAPP as required to alleviate a number of the shortfalls.

South Africa appears to be getting round to addressing the technology shortfall. Eskom just lately introduced 4 months of uninterrupted energy provide since 26 March 2024, together with 87 days of fixed provide all through the winter interval. The suspension of load-shedding in South Africa has introduced some aid to properties and enterprise that had been dealing with spiraling prices from utilizing different sources reminiscent of diesel backup turbines. Eskom reached one other important milestone on 23 July 2024 by reaching 35,000 MW of accessible capability, with a night peak demand of 30,740 MW. This stage of accessible capability has not been seen for six years, particularly since 16 July 2018. This achievement is attributed to lowered unplanned outages, which have dropped to 9,238 MW. Moreover, Eskom achieved a mean Vitality Availability Issue (EAF) of 70% over the previous seven days.

Eskom provides that its “Technology Restoration Plan” continues to ship efficiencies, with an approximate R9.09 billion discount in Open-Cycle Gasoline Generators (OCGTs) diesel expenditure from 1 April 2024 to 25 July 2024, in comparison with the identical interval final 12 months. Eskom had been spending some huge cash on diesel. It’s good to see that rooftop photo voltaic is beginning to contribute a substantial portion of South Africa’s electrical energy technology combine throughout daytime hours.

The scenario isn’t so good for Zimbabwe and Zambia. Zimbabwe and Zambia share the Kariba Dam. The Kariba Dam was constructed between 1955 and 1959 and extends for about 280 km. It holds about 185km3 of water. On the Zimbabwe aspect (Kariba South), the hydropower plant now has an put in technology capability of 1,050 MW. On the Zambian aspect (Kariba North), there may be now an put in technology capability of 1,080 MW, so due to this fact the dam has a mixed capability of two,130 MW. The dam is a serious vacationer attraction for the nation, second solely to Victoria Falls. Lake Kariba can be now residence to the world’s most efficient reservoir fishery, and due to this fact a supply of employment for the artisanal fishing business.

The massive downside is that there’s a critical drought at the moment affecting numerous nations in southern Africa. Some stories say that is the worst drought in over 100 years. The issue is that these droughts have gotten too frequent and growing in severity. The Kariba Dam’s water ranges are extraordinarily low in the mean time on account of these droughts, as illustrated beneath:

The low ranges have pressured the Zambezi River Authority to limit electrical energy technology from Kariba Dam. Zimbabwe now has an put in capability of about 2,500 MW. Nonetheless, because of the low water ranges in Kariba, ZPC, the nationwide electrical energy technology firm, has been pressured to scale back technology at Kariba to solely 215MW out of 1,050MW! Together with depressed technology at some outdated coal energy crops, the whole technology capability has been hovering at round 1,300MW. With demand reaching near 2,000 MW, Zimbabwe has been pressured to implement extreme electrical energy rationing cycles, which imply most residents don’t have electrical energy from about 6am to 9pm every day.

In Zambia, the put in nationwide technology capability stands at round 3,500 MW in comparison with a peak nationwide demand of roughly 2,300MW. Nonetheless, attributable to restricted technology at Kariba North in addition to different crops being out for scheduled upkeep, obtainable technology capability is hovering round 890MW, forcing the utility firm to extend load-shedding to 17 hours a day!

If the area’s leaders have been taking note of world developments, they’d know that there has by no means been a greater time to do that. Numerous progress has been made within the photo voltaic and stationary vitality storage segments with rising market shares in numerous nations within the developed world. The unbelievable ramp-up of manufacturing capability in these sectors, in addition to technological developments over the previous decade, helped unlock efficiencies in key areas, leading to unbelievable value drops in the price of manufacturing of all of the important substances. This has resulted in customers now gaining access to photo voltaic panels and batteries at costs decrease than ever.

Photo voltaic panel costs are so low now that we now hear stories that it’s cheaper to purchase photo voltaic panels and use them to assemble fences in some locations in Europe than to make use of conventional fencing materials! A fence that additionally generates clear electrical energy — how cool is that? You realize what could be cooler? Utilizing all this PV and battery storage to energy distributed microgrids utilizing a whole bunch of 1000’s of rooftops and carparks throughout these nations to enhance the availability from present utility-scale technology crops. The drastic drop in costs of photo voltaic panels and batteries imply that rather a lot much less cash is required to set all this up now in all these nations than ever earlier than.

South Africa confirmed us simply how rapidly new technology capability could be added from rooftop photo voltaic. South African properties and companies have added 3,526 MW of rooftop photo voltaic in simply two years! It’s simply fantastic to see how briskly electrical energy technology capability could be added from rooftop photo voltaic. In response to knowledge from Eskom, there have been about 2,264.5 MW of rooftop photo voltaic PV put in in South Africa as of July 2022. In response to Eskom’s newest replace, South African properties and companies have now put in 5,790.5 MW of photo voltaic PV.

Different sources could be thought-about as nicely so as to add to the technology mixture of SADC member nations. We simply want the regional leaders to indicate a bit extra urgency. Right here is a abstract of the outcomes of the Summit. Doesn’t seem like there was a transparent and pressing name to deal with the electrical energy disaster. The entire different themes from the summit, reminiscent of “Selling Innovation to Unlock Alternatives for Sustainable Financial Progress and Growth in direction of an Industrialised SADC,” should be backed up by a secure electrical energy atmosphere. For SADC to industrialize, it should prioritize fixing this electrical energy disaster.
