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.

SA cannot sustain momentum - Boesak

South Africa finds it increasingly difficult to live up to the challenges facing it as a nation because of its failure to meet its democratic ideals and possibilities, peace and lack of self-belief.

This was according to renowned cleric and former political activist, Dr Allan Boesak, who recently delivered the CR Swart Memorial Lecture, the oldest memorial lecture at the University of the Free State (UFS). His lecture was on the topic Creating moments, sustaining momentum.

He said South Africa had plenty of opportunities to show the whole world what was possible if all the people of this country joined hands and worked together to build a truly united society. However, he said, the country somehow invariably contrived to find its way out of these wonderful possibilities.

He cited events of historical significance like Codesa, the inauguration of Nelson Mandela as the first democratic president of South Africa, the assassination of South African Communist Party leader, Chris Hani; and the rugby and soccer world cups.
To drive his point home about this dismal failure of the country to “sustain momentum”, he alluded to the current public servants’ strike that is gradually crippling public service.

“The public servants’ strike was neither unexpected nor is it completely unjustifiable. Most of us have understanding for the frustration of teachers and health workers. Their demands resonate with most of us, and I think that it is scandalous of SACP fat cats to tell workers to “stop crying like babies,” he said.

He also added to the criticism of the much-maligned decision of the government to spend billions of taxpayers’ money to purchase weapons when there was “no discernible military threat” to the country. He said the greatest threat to the security of the country was poverty, inequality and social cohesion.

“As for the argument that arms sales bring in foreign exchange – how can we be instrumental in killing the poor elsewhere with the intention of feeding our poor, and then our ill-gained profits feed only the already well-fed?” he asked.
“Can we see the hopeless contradiction, the total impossibility of being both the apostle of peace and a merchant of death?”

He also lambasted the Black Economic Empowerment (BEE) policy of the government which he said benefited only those connected to the political aristocracy.

“It couples with the unashamed, in-your-face display of wealth by the privileged elite in this country, the crass materialism of the so-called “bling generation”, and the casual carelessness with which promises to the poor are given and treated. It is only the public symptom of the deep-seated scorn our political elites feel for the poor,” he said.

He said the government’s disdain to the poor was “setting fire to our future”.

“The anger of people on the ground can no longer be denied or ignored, and little by little, the leadership articulating and directing this anger is being estranged from politically elected leadership, and even more disturbing, from our democratic processes,” he said.

He concluded that the country’s difficulty in dealing with race and racism was putting the reconciliation process kick-started by Mandela just over a decade ago, under a threat.
