The Independent Power Producer Office (IPPO) reports that it is engaging with Eskom on its newly released curtailment addendum to the latest Generation Connection Capacity Assessment (GCCA 2025) – through the addendum 3 470 MW of additional connection capacity for wind generators has been unlocked in two grid-constrained provinces. Prior to the publication of the addendum, the GCCA 2025 indicated there to be no remaining grid capacity available in the Eastern, Northern and Western Cape provinces. But the addendum indicates that, by accepting a “reasonable share of no more than 10% of curtailment”, 2 680 MW of capacity is available in the Western Cape and 790 MW in the Eastern Cape.
The City of Cape Town’s (CoCT’s) specialist metals theft unit, the Copperheads, has recovered more then 53 km of stolen cable during the last six months of 2023. The unit says it executed 404 autonomous operations, 1 260 scrapyard inspections, 1 777 hotspot patrols and responded to 277 complaints from the public during this period.
Loadshedding will jump to Stage 3 at 16:00 Monday after a delay in the return to service of two generating units. “Over the past 24 hours, five generation units were taken offline for repairs. Additionally, the return to service of two generating units that were on planned maintenance was delayed due to an opportunity to perform preventative maintenance. These factors have contributed to the shortage of available capacity necessitating the implementation of Stage 3 loadshedding from 16:00 today until 05:00 on Tuesday,” Eskom said. “Thereafter, loadshedding will be reduced to Stage 2 until 16:00 on Tuesday. This pattern of Stage 2 loadshedding from 05:00 until 16:00 and Stage 3 loadshedding from 16:00 until 05:00 will be repeated daily until further notice.”
The National Nuclear Regulator (NNR) has announced that it has approved the request of national electricity utility Eskom to separate the operational timelines for the two reactors of the Koeberg nuclear power plant (NPP). Koeberg, located on South Africa’s west coast, near Cape Town, is the country’s (and still Africa’s) only operating NPP. (The continent’s second NPP, El Dabaa in Egypt, is still under construction.) The two reactors were designed Unit 1 and Unit 2. “After completing its safety assessment, the NNR confirmed that the approval of the separation of the units will not impact the safety of the Koeberg nuclear power stations,” reported the regulator, in its press release.
Eskom has taken a major step in unlocking much-needed grid capacity for wind projects in the Western and Eastern Cape provinces by publishing the highly-anticipated curtailment addendum to its latest Generation Connection Capacity Assessment, or GCCA 2025. The addendum, which has been published on Eskom’s website and has been approved by the National Energy Regulator of South Africa (Nersa), states that, by accepting a “reasonable share of no more than 10% of curtailment”, 3 470 MW of additional grid capacity to connect wind generation will be made available, including 2 680 MW in the Western Cape and 790 MW in the Eastern Cape.
Engineering News editor Terence Creamer discusses government’s proposal to set up a dedicated entity to procure new electricity transmission infrastructure from the private sector and the role government expects the private sector to play in the area of the grid.
Plan to apply the Minimum Energy Performance Standards (MEPS) for low-voltage electric motors in South Africa have been hailed by solutions provider WEG Africa as an exciting step toward energy efficiency and a lower carbon future for the industry. The Department of Trade, Industry and Competition recently announced its intention to put a stop to imports of low-efficiency motors – in the power rating range from 0.75 kW to 375 kW – in favour of motors in the efficiency class of IE3 and above.
South Africa’s electricity problems have left the country without power for many hours a day, causing grave difficulties for businesses and households, notes power generation and electromechanical power transmission product supplier Vert Energy. “The inability of the country’s primary electricity supplier to meet demand has called for the private sector to step up and provide solutions that help keep businesses, education facilities, hospitals and more running, in the event of power outages and loadshedding,” explains Vert Energy sales and marketing director Ryan Robertson.
Grid-scale energy storage solutions company Energy Vault has signed a licensing and royalty agreement with a South African consortium, established with the aim of deploying the NYSE-listed company’s gravity energy storage systems across the 16 countries that make up the Southern African Development Community (SADC) bloc. The agreement is with Gravity Energy Storage Solutions (GESSOL), an entity comprising JSE-listed construction group WBHO, iX Engineers, and Sizana Solutions, which has been partnering with Energy Vault in Southern Africa since 2019.
The global and local renewable energy transition is presenting industries, and South Africa, with a once-in-a-century growth trajectory to provide products and components into the value chains of renewable energy and battery energy storage systems (BESSs). During the second quarter of 2023, more than $1.7-billion worth of solar panels, inverters and lithium-ion battery systems were imported into South Africa, and this number excludes other components and parts.
