Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050.
Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050.

Energy efficiency and renewable energy is the game for South Africa to transition to a carbon-friendly economy by 2050. The energy mix by 2050 is focused on renewables and the long-term journey is very clear: we have to be renewable driven.

This is according to panellists speaking at the University of the Free State’s (UFS) third webinar in the 2022 Thought-Leader webinar series. The webinar titled, What needs to be done to POWER up South Africa? comprised panellists Matthew Mflathelwa, General Manager: Strategy and Planning at Eskom; Steve Nicholls, Head of Mitigation at South Africa’s Presidential Climate Commission (PCC); Happy Khambule, Environment and Energy Manager at Business Unity South Africa (BUSA); and Louis Lagrange, Head: Department of Engineering Sciences in the Faculty of Natural and Agricultural Sciences, UFS. 

We need to invest in new infrastructure

In his presentation, Mflathelwa talked about how Eskom can unlock additional grid capacity and how to start rolling out business models to enable this transition. 

“On the demand side, we are looking at some exciting and interesting initiatives. We are looking at how we can start to aggregate or leverage the idea of consumers becoming prosumers, and leverage technology to aggregate the potential supply and management demand from that perspective.” 

“The question is also how to do this sustainably in the long term. We need to invest a considerable amount of new infrastructure,” said Mflathelwa. 

According to him, it is not a secret that most of Eskom’s generating assets are approaching the end of life. The question now is how to proactively plan for this to ensure that we address the problem of load shedding sustainably. “The big takeaway is that there is a significant amount of new capacity that needs to be built and this is predominantly going to be renewables, but it is not the only additional infrastructure that is required. We need an energy mix that can respond and achieve adequacy for the future requirements.”  

Another important element that is often neglected is the transmission of grid infrastructure, given the penetration or entry of new players with greater penetration of renewable energy and the advantages that come with distributing these energy sources across the country. There is a lot of transmission and distribution infrastructure needed to enable this future capacity.

Some of the things also being discussed, said Mflathelwa, are how to enable greater and faster penetration of new capacity – specifically renewables to aid in the reduction of environmental challenges.

What needs to be done to POWER up South Africa 
(Recorded on 27 September 2022)

 

The next decade is critical 

Nicholls gave a climate-friendly perspective on the work that Eskom is doing, saying energy transition in SA is core to the overall economy transition and getting a zero-carbon, least-cost energy system is fundamental to the strategy of the country. 

“We need to move from carbon emissions of around 480 megatons per annum today to somewhere between 350 and 420 by 2030, and then onto zero carbon emissions by 2050. If South Africa is to reach net-zero by 2050, we need targeted investment between now and 2030, setting the stage for accelerated investment in decarbonisation post 2030. The next decade is critical. Given the state of South Africa’s balance sheets, international support and foreign direct investment are critical.”

Nicholls said the energy mix by 2050 is really focused on renewables, and the long-term journey is very clear: we have to be renewable driven. The short- and long-term solutions are alike; renewables are cheaper, quicker to get onto the grid, pending some investment in the grid.   

“In the long term, we need big investments in renewables – about 6 GW a year between now and mid-2050. We need a big investment in the transmission grid. Hydrogen plays a critical role in decarbonisation of power and industry. Energy efficiency is key. It’s really the unsung hero in this conversation. If we can be energy efficient, we can take two power stations off the grid and that makes a big difference in terms of affordability.” 

“Transport is also important; if we are going to be a net-zero economy, we have to fully electrify the transport fleet, which puts an extra load on what Eskom needs to achieve,” Nicholls said. 

Energy efficiency is most critical

Khambule emphasized that the country needs to focus on using energy in an efficient manner in the commercial and household sectors, as energy efficiency is critical to the country’s power supply issues in the short term. According to Khambule, the country is not using energy in an efficient manner.

"If we are able to use power the minute it is necessary and become more efficient with it, we can get more value out of that power," said Khambule.

Lagrange concurred with Khambule on the importance of energy efficiency, referring to it as ‘the unsung hero’. “Energy efficiency is the biggest solution that we can have, and people need to be trained on how to use energy efficiently,” said Lagrange.

Khambule also addressed the issue of power cuts, saying the unpredictability thereof, even in the short-term, further exacerbated the situation.

"The unpredictability of load shedding has become much more of a driver for uncertainty, which leads to a lack of business confidence, and secondly leads to losses in production;  a key notion is that if we have predictability of load shedding, planning can be undertaken, and if planning is undertaken in a more judicious manner, then we are at least able to keep the losses at a minimum and see how we can weather the storm until a sustainable supply can be implemented."

Khambule also added that in the short and mid-term, solutions must consider protecting or mitigating options for vulnerable sectors. “In some industries – such as health care, power is essential and there is a need for predictable supply. Therefore, some sectors will require mitigating solutions to protect some essential sectors,” said Khambule.
According to Lagrange, no amazing technology for the generation and distribution of energy has been developed over the past decade. “We need to reimagine the entire current regulatory systems business model, because it is caught up in an energy stagnation, which is frighteningly fragile from a physical and cyber-security point of view,” added Lagrange.

Centenary medals awarded
2004-10-15

Speech, Rector and Vice-Chancellor: Prof. Frederick Fourie

Op 28 Januarie 2004 het ons die honderdste herdenking van die geboorte van hier­die hoër onderwys instelling gevier met ‘n groot partytjie voor die Hoofgebou. Dit was ‘n wonderlike en vreugdevolle aand.

Die historiese prosessie tydens die amptelike opening van 6 Februarie 2004, in kleurvolle akademiese togas, vanaf ons wortels in Grey-Kollege tot by die Hoof­gebou, het die reistog vanaf die verlede na die hede treffend ge­simbo­liseer.

Talle ander eeufeesgeleenthede het gedurende hierdie jaar plaasgevind. Woensdagaand het ons die premiêre van ‘n dokumentêre film oor koning Moshoeshoe beleef – ‘n belangrike eeufeesprojek van die UV wat onder meer gemik is op die ontwikkeling van ‘ n gedeede geskiedenisbesef – a shared sense of history – and the celebration of a very special leadership, of a spirit of nation-building and reconciliation, in somebody like king Moshoeshoe (also MT Steyn and others…)

Last night we experienced a wonderful and moving honorary doctorary ceremony, with a wonderful group of South Africans like Khotso Mokhele, Antjie Krog, Jakes Gerwel, Van Zyl Slabbert, Jaap Steyn, Saleem Badat, and others - giving so much food for thought.

This evening, where we honour outstanding contributors to the development of this University, is a suitable moment to reflect on the course of the first 100 years of the University of the Free State.

1. ‘n Voëlvlug oor die geskiedenis: die vyf fases

1.1 Eerste fase: 1904 – 1927 (Eerste kwarteeu)

Eerste wankelende treë in die totstandkoming van die
Grey Universiteitskollege

Gedurende 1904 – 1920 word die eerste en mees basiese vakke in geestes- en natuurweten­skappe ingestel, eerste Senaat en eerste Raad saamgestel, en eerste geboue opgerig (hoofgebou en manskoshuis). Teen 1920 was daar egter slegs ongeveer 100 studente, die instelling was finansieel in die knyp, met geen vooruitgang en groei, en ook nie ‘n vaste rektor nie – klaar­blyk­lik was die GUK nog geen lewensvatbare instelling nie. Vrystaatse kinders word steeds eerder na ander universiteite gestuur.

Hierna maak ds JD Kestell, rektor 1920 – 1927, ‘n reuse bydrae om ‘n versukkelde, arm, klein universiteitskollege lewensvatbaat te kry. Hy slaag met fonds­insameling en oortuig Afrikaanse én Engelse ouers om hulle kinders na die GUK te stuur. Teen 1927, met 420 studente, word die eerste nederige mylpale van kritiese massa bereik te midde van ‘n steeds armoedige Vrystaat­se gemeenskap en ‘n studentekorps met gelapte klere. [Maar ook die tyd waarin die Reitz-saal, waarin hierdie plegtigheid plaasvind, gebou is.]

1.2 Second phase: 1927 – 1950 (Tweede kwarteeu)

The Grey University College becomes a fully fledged university

By 1950 the establishment of main basic and career-oriented faculties were completed – Faculty of Commerce in 1937; Faculty of Law as wel as the Faculty of Education in 1945. Student numbers reached 1000 in 1950.

Die UKOVS beleef en oorleef die Groot Depressie, die armblankevraagstuk, die Tweede Wêreldoorlog, taal- en politieke stryd onder Afrikaners, en die stryd van Nat vs Sap, ook op die kampus. Die tydperk word veral gestempel deur die taalstryd met DF Malherbe (rektor 1929 – 1934) as sterk kampvegter vir Afrikaans. Veral na 1948 volg rektor Van der Merwe Scholtz ‘n doelbewuste enkel­talige Afrikaanse rigting (Christelik-nasionaal).

1.3 Derde fase: 1950 – 1976 (Derde kwarteeu)

Ongekompliseerde groei ná onafhanklikheid

Hierdie periode word gestempel deur verkryging van onafhanklikheid as universiteit op 18 Maart 1950. Daarna beleef die UOVS onder rektore Scholtz, Flippie Groene­woud en Benedictus Kok stelselmatige groei sonder beduidende finansiële kommer. Die UV is duidelik ‘n Afrikaanse ‘volksuniversiteit’ op Christelik-nasionale grondslag, onlosmaaklik in­gebed in die dominante politieke bedeling van apartheid en afsonder­like ontwikke­ling. Dit is die hooggety van Afrikaner (en blanke) self­vertroue en heerskappy. Vir personeel sowel as studente is dit ‘n relatief onge­kom­­pliseerde tyd getipeer deur groeiende voor­spoed in die blanke en Afrikaanse gemeenskap, goeie werksvooruitsigte vir studente, kommer­lose studentepret, en min spanning op die kampus.

The academic focus is on teaching, especially to provide staff for the growing public service and education sectors. Research has a low profile. More career-oriented or professional faculties are established: agriculture in 1958 and the medical faculty in 1970. Student numbers reach 2000 in 1960, 4000 in 1970 en 7000 in 1975. Many new residences and academic buildings are erected, especially in the Kok-era.

Teen 1976 was die vernaamste boustene van ‘n medium-grootte universiteit in posisie: onafhanklikheid, genoeg fakulteite, genoeg koshuise en akademiese geboue, goeie sport en kultuur. Op die oog af is die ideaal van volwaardige, onaf­hanklike universiteit verwesenlik.

1.4 Vierde fase: 1976 – 1989

Op koers na die jaar 2000: van die statiese na vernuwing

Politieke onstabiliteit en oorgang in die land begin met die Soweto-onluste, die drie-kamer parlement, PW Botha se Rubicon-toespraak, noodtoestande, die ‘struggle’ en opkoms van UDF, en so meer. Die UOVS is swaar onder die indruk van die ‘totale aanslag’ en die regering se totale teen-strategie. Die Universiteit word polities en akade­mies geïsoleer en intellektueel gemarginaliseer. Ekonomies is dit moeiliker tye na die oliekrisis en die begin van hoë inflasie, en die Staat se finansies wat begin knyp.

Academically this period is distinguished by the strong stimulation and support of the research capacity and orientation by rector Wynand Mouton, which leads to a significant growth in research, especially in the natural sciences. The faculty of Theology is establishyed, the Sasol-UFS library erected. Student numbers continue to grow, but at a much slower rate then before.

Twee ander fasette kenmerk hierdie tydperk: eerstens die toelating van die eerste swart studente (nagraadse 1978, voorgraads 1988) en die begin van die era van multikulturaliteit; tweedens, die begin van subsidie- en finansiële probleme en die eerste rasionalisasie van personeel. Albei hierdie is voortekens van ingewikkelde jare wat sou volg vanaf 1990.

1.5 Fifth phase: 1990 – 2004: The turn of the century brings winds of change

(a) 1990 – 1996:

Die Francois Retief era word gedomineer deur die gevolge van die politieke verande­ringe deur president FW de Klerk en die vrylating van Nelson Mandela. Die UV ontwaak tot die realiteit van die oorgang na ‘n post-apartheid samelewing en komende ANC regering. Die eerste versigtige trans­for­ma­sie­stappe word ingestel, multikulturaliteit word die groot uitdaging, en die eerste fasiliterende strukture (bv. die Multikulturele Komitee) word gevestig. Die eerste senior swart personeel word aangestel.

The dramatic decision about the introduction of parallel-medium teaching in 1993 signals the start of multilingualism as well as a significant growth in the admission of black students. Total student numbers are stable at approximately 9000, but black student numbers grow to 36% in 1995. Initially the change to parallel-medium impact negatively on staff teaching load and hence onresearch outputs.

Die inkrimping in staatsubsidie lei tot ernstige finansiële probleme, besparings­pogings, grootskaalse rasionalisasie van personeel in veral die fakulteit Lettere en Wysbegeerte, spanning tussen Senaat en rektoraat oor finansies – en mismoedig­heid onder personeel.

(b) 1997 – 2004:

The time of rector Stef Coetzee and his successor is the era of the new democracy and transformation. At the beginning of this phase Afrikaans parents start sending their children to other Afrikaans universities; residence become half full. Tensions arise between student groups. This is followed by the large breakthroughs in student transformation in 1997, which normalises the situation. The University becomes a leader in transformation. This leads to the acceptance of the multicultural and multilingual character, on a Christian foundation, of the University. The name changes to the University of the Free State (UFS).

Met ‘n finansiële krisis en verdere rasionalisasie van personeel op hande word die akade­miese en finansiële ‘draaistrategie’ in Januarie 2000 geloods. ‘n Drama­tiese finansiële ommekeer lei tot herinvestering in kampus­fasiliteite en toerusting, ‘n toename in personeel en beduidende verhoging in vergoeding bokant inflasie. Terselfdertyd is daar ‘n opbloei in die akademie: innoverende onderrig­programme, e-leer, ‘n fokus op programgehalte. Konsolidering van fakulteite vind plaas, die Bestuurskool word gestig, daar is sterk internasio­na­lisering en groei in navorsing. Profes­sionele bemarking en strategiese kommunikasie verander die beeld van die UV.

Studentegetalle groei dramaties van 10 000 in 2000 na meer as
23 000 in 2003/4; groei moet nou beperk word. Afrikaanse studente keer terug; koshuise kry lang waglyste. Die verhou­ding tussen wit en swart studente op die hoofkampus is rondom 50:50.

The period ends with the incorporation of the Qwaqwa en Vista Bloemfontein campuses, the approval of a new language policy which also established multilingualism in management and administration, and purposeful efforts to consolidate the foundations of an institutional culture of multiculturalism, multilingualism, non-racialism and non-sexism – a culture of tolerance, embracement and justice in diversity. The Centenary is celebrated with harmony and prosperity on the campus in 2004 (although always with a good sprinkling of unexpected challenges and problems).

2. Vanaand bring ons hulde, en sê ons dankie aan, die bouers van die UV

Oor ‘n honderd jaar het honderde, duisende mense ‘n bydrae gelewer tot die UV se ontwikkeling.

Kom ons eer en dank diegene wat, 100 jaar gelede in a baie arm gemeen­skap wat bykans verwoes is deur die Anglo-Boere oorlog, nooit opgehou droom het oor ‘n eie universiteit om die jongmense te dien, om die mense te dien – die arm Vrystaatse mense van daardie tyd.

Let us honour and thank all those who painstaking built this university from very humble beginnings, from the first fragments and embrio of a university – through a hundred years of various wars, of the struggle, of poverty, of bad times but also good times.

In elke dekade, in elke een van die honderd jaar, is hierdie instelling gebou deur die harde werk, idealisme en verbintenis (“commitment”) van leiers, akademiese personeel, steundiens­personeel, dienswerkers. Laat ons hulle eer en dank.

Let us honour the spirit of commitment and ‘vasbyt’, of ‘never let go’, the determination to overcome obstacles, of timely and pre-emptive adjustment to new challenges and new needs, which made that possible.

Kom ons vier en eer die duisende studente wat in die 100 jaar hier was, wat die spesiale tradisies en spesiale gees geskep het van Kovsiekampus, van Kovsie studentelewe – en wat gedurig nuwe tradisies en gebruike geskep (en gepleeg) het, soos net studente dit kan doen.

Let us celebrate the way this University has, in the last 20 years, once again taken up the challenge of transformation and adjusting to new needs, serving all the people, especially those most in need at this time of our history – thereby closing the circle, going fully “from post Anglo-Boer War to Post-Apartheid”.

Kom ons vier, en wees innig dankbaar vir, die wyse waarop hierdie Universiteit in die laaste 5 jaar gedraai het, finansieel sowel as akademies, en die wonderlike periode van akademiese groei en ontwikkeling en verdieping waarin ons nou staan – tesame met die geleenthede wat QwaQwa en Vista Bfn vir ons bied. Hierdie voorspoed sien ons in die nuwe fisiese aangesig van die kampus, insluitend hierdie wonderlike Eeufeeskompleks.

Let us thank God, the Almighty, who has guided this university through a tumultuous century, for always being there for us, for blessing us in so many ways. In Deo Sapientiae Lux

So: vanaand is ons hier om erkenning te gee en dankie te sê…

Soveel mense het veel vroeër hul fondament-leggende bydraes gelewer, en alles wat ons vandag hier sien, moontlik gemaak. Selfs mense uit meer onlangse jare is reeds oorlede – enkeles terwyl hulle nog in diens van die UV was, ander na hul aftrede.

‘n Bepaalde groep was bevoorreg en geseend om in die laaste ongeveer 30 jaar by die UV betrokke te kon wees, én om vandag nog in die lewe te wees. Dit is van hulle wat vanaand hier is, en wat vanaand Eeufeesmedaljes ontvang.

Geweldige moeite is gedoen om hierdie proses van seleksie en keuring so billik en deeglik as moontlik te doen. Uiteraard is so ‘n proses nie volmaak nie en sal almal nie saamstem met die uitkomste van die proses nie. Groot moeite is egter gedoen in hierdie fase om mense nie verkeerdelik uit te laat uit of in te sluit in die toekenningslys nie, in volle bewustheid dat daar waarskynlik steeds foute gemaak sal word. Onvermydelik sal daar foute wees, of mense wat uitgelaat is. Ons vra daarvoor nederig om verskoning en begrip.

Billikheid, so ‘n belangrike rigsnoer vir hierdie Universiteit, veral in hierdie tye, lei ons ook dat ons oë oop is vir die bydraes vir mense uit alle afdelings van die Universiteit, wat lei tot ‘n bepaalde balans tussen fakulteite, tussen fakulteite en steundienste, tussen poskategorieë, tussen geslag en ras, en individue soveel as mense in spanverband.

In Deo Sapientiae Lux
