The newly installed solar plant at Sun International’s Sun City, in the North West, is exceeding expectations, having saved the company over R1-million over the past two months. The R16-million, grid-tied, 1.4 MW installed capacity system, with 2 584, 550 W monocrystalline solar photovoltaic modules, was installed on the roof of Sun City’s conference and entertainment centre earlier this year to reduce the resort’s reliance on South Africa’s electricity grid.
Engineering News Editor Terence Creamer discusses Eskom’s plans to roll-out a new virtual wheeling platform that could unlock renewables supply to companies with operations spread across the country.
Amid local energy constraints and a global focus on increasing renewable energy capacity, the importance of ensuring that proper planning is implemented as South Africa transitions to cleaner energy was highlighted during a roundtable discussion at this year’s South African (SA) Auto Week, hosted by naamsa | The Automotive Business Council, in Johannesburg, from October 11 to 13. During the discussion, a need to diversify the energy mix and ensure a stable baseload energy supply was discussed, with South African Nuclear Energy Corporation CEO Loyiso Tyabashe arguing that nuclear energy can contribute towards a diversified energy mix.
The credit risk associated with municipalities in arrears to Eskom poses a challenge to the roll-out of the utility’s proposed virtual wheeling platform and is also likely to limit the ability of corporates with distributed facilities to rely exclusively on virtual wheeling as currently conceived to meet their net-zero commitments. Eskom aims to launch the platform – which allows for one or more generators to transact with multiple customers that have disbursed operational footprints, including ones located in municipal distribution areas – in the second half of 2024.
The South African Revenue Service led a large-scale government search and seizure operation against several alleged members of coal smuggling syndicates across the country on Thursday, including former Eskom employees. “The alleged coal-smugglers and their related entities are active and have a presence in Gauteng, Mpumalanga, KwaZulu-Natal, the Free State and Limpopo,” the tax authority said in a statement. “The suspects targeted today include former Eskom employees who facilitated procurement fraud, as well as other individuals involved in the diversion of high-grade coal.” Sars said it established that the suspects had contravened several tax laws, including non-registration for income tax, failure to submit tax returns, under-declaration of income, claiming undue VAT refunds, and making false submissions. Sars put the loss of revenue to the fiscus by the syndicates at over R500-million. Coal smuggling syndicates have been a consistent problem for Eskom. Often, trucks transporting coal to power stations are diverted to specific coal yards, and high-quality coal is swapped out for low-grade product, scrap or rocks. When the lower-grade products are used at the station, they cause infrastructure damage, rendering them unable to generate electricity, leading to more loadshedding. Sars Commissioner Edward Kieswetter said the raids were a massive breakthrough in ongoing investigations into the syndicates.
The South African Revenue Service and other government agencies said they disrupted a coal smuggling syndicate operating across five of the country’s nine provinces. The search-and-seizure operation targeted former employees of state power utility Eskom Holdings “who facilitated procurement fraud,” the agencies said in a statement on Thursday.
Steel producer ArcelorMittal South Africa (AMSA) is moving ahead with a study into the production of green hydrogen directly reduced iron (gHDRI) at its mothballed Saldanha Steel Works, in the Western Cape. Market and product development head Jerry Dungu told participants at an industry conference that the JSE-listed group had signed a memorandum of understanding with a “developer of transformational energy solutions” to advance the production of gHDRI at the plant.
As infrastructure engineering software company Bentley Systems gears up to host its 2023 Going Digital Awards in Infrastructure, on October 12, three Chinese finalists in the process and power generation category have illustrated the efficiencies that can be achieved with digital twinning. The finalists presented their projects to a panel of independent judges to determine the ultimate winner of the category, having used digital technologies such as Bentley Infrastructure Cloud, iTwin Platform and Bentley Open Applications to maximise efficiency and achieve cost savings for clients.
Harnessing the potential for renewable energy and green hydrogen production, or replacing carbon atoms with hydrogen atoms in the energy value chain, can build peace and stability in Africa, petroleum company Conex Liberia MD Amitahb Prasad has said. “By 2035, Africa can produce 50-million tons of competitively priced green hydrogen. The expected global demand for green hydrogen is 607-million tons by 2050. In comparison, Africa’s demand for green hydrogen and its derivatives is expected to reach 10-million to 18-million tons a year by 2050, but with a production potential much above that.
The City of Cape Town says its “rooftop solar boom” has reached a new record, with August seeing the highest ever level of solar photovoltaic (PV) installation applications.  More than 1 500 small scale embedded generation (SSEG) applications were received in August, which is a 50% increase compared with July, the previous record month at around 1 000 applications.
