Looming Shortage
Gas users call for urgent stakeholder engagements to avoid supply ‘cliff’ when flows from Mozambique end in 2026
Large industrial gas users are starting to prepare for what will likely be South Africa’s next big energy crisis, the imminent shortage of natural gas.

Sasol, as the monopoly supplier of large-scale natural gas, in August last year announced that South Africa was heading for a “gas cliff” in that supply of gas to industrial users will be suspended by June 2026.
This suspension relates to gas flows from Pande and Temane, in Mozambique, drying up. These resources were secured by Sasol alongside the South African government in the early 2000s. Although there are major gas developments under way in Namibia and Mozambique, these are of little consequence to South Africa owing to infrastructure limitations to gas-demand nodes such as Gauteng.
Similar restrictions inhibit the potential use of any gas recently found by Total at the Brulpadda and Luiperd prospects off South Africa’s Southern Cape coast.
The economic feasibility of all other prospective developments, such as Kudu, Karoo shale, Mamba and Lesedi, is unproven and has no clear timeline for development.
Lower to no gas supply poses an existential threat to South Africa’s manufacturing base, since many primary manufacturers, including members of the Industrial Gas Users Association of South Africa (IGUA-SA) such as ArcelorMittal, Mondi, Illovo, South32, South African Breweries, Hulamin, Coca-Cola, Nampak and Scaw Metals Group, rely on gas for industrial processes.
South African industrial gas users directly employ 70 000 people and contribute between R300-billion and R500-billion a year to the economy. A cessation in the supply of gas, particularly in Gauteng and KwaZulu-Natal, would result in multiple plant closures and a significant reduction in manufacturing output.
Besides the risk to the country’s manufacturing capacity, more than 400 small- and medium-sized enterprises, several hospitals and about 8 000 households would be directly affected by a suspension of gas supply.
Gas is also essential for decarbonisation purposes, which will set South Africa further behind on its climate change mitigation targets.
IGUA-SA CEO Jaco Human said at a media briefing hosted on February 27 that there were no confirmed supply solutions that would come on stream early enough to act as a sufficient source of independent supply.
As it stands, there will be a 12- to 18-month gap between day zero when Sasol suspends its supply and the finalisation of any feasible replacement supply.
Where possible, businesses would be forced to switch to fuels that were more expensive and more environmentally damaging, with repercussions for consumer pricing and carbon emissions. In many instances, fuel source substitution would not be economically or practically feasible, Human explained.
The knock-on impact of gas shortages would be acutely felt by consumers through supply shortages and price increases across the steel, aluminium, mining, agriculture, paper, glass, ceramics, construction, automotive and food and beverage sectors. This would also extend across indirectly related industries that supply these manufacturers.
A lack of gas would also pose a threat to South Africa’s regional competitiveness and its balance of payments.
Human believes the next four months will be crucial to develop the required agreements for gas infrastructure to substitute the shortfall in supply from 2026 onwards. IGUA-SA is urgently calling on government, as it has since 2019, to engage with key stakeholders in industry to find a solution to this potentially devastating crisis.
Human said the gas cliff started with energy shortages being noted since 2019, with limited to no gas pipeline and receiving infrastructure being built in South Africa. There had also been policy uncertainty as to the future role of gas in South Africa’s energy mix.
This while South Africa has massive offshore gas potential. “The South African State has certainly been in abeyance, with no direction or investment from government. This has resulted in complete market uncertainty,” he adds.
Human said industry had consistently argued for the Gas Utilisation Master Plan to be finalised and released for public comment.
If gas was to play the balancing role contemplated in the Integrated Resource Plan, then the infrastructure location of gas-to-power generation facilities and the source of the gas had to be urgently prioritised and rigorously interrogated.
With a gas cliff only 30 months away, industrial gas users have started looking into establishing a gas aggregator entity, which can take responsibility for infrastructure investments and underwrite volume flow. This entity may also be able to conclude offtake agreements with gas suppliers and pipeline companies, and trade on a not-for-profit basis, simply to cover costs.
The entity’s commercial participation would be based on volume proportionality. It would be owned by offtakers, including industrial gas users and possibly entities such as the Central Energy Fund and Eskom.
However, since it is not feasible for industry to single-handedly invest in and develop national-scale private natural-gas infrastructure – including bulk pipelines, liquefied natural gas (LNG) port terminals and regasification terminals – urgent action is required on the part of the South African government to adequately address this crisis, the IGUA-SA states.
Sasol has advised that it will embark on a reasonable, phased reduction of supply, which could be gradually offset by increased reliance on other sources, instead of a unilaterally imposed hard cut-off, however, this is not a long-term solution.
Ultimately, IGUA-SA hopes government will create volume scale, or demand aggregation, with the private sector to finance projects feasibly. The South African economy also requires the State to be a catalyst rather than a controller of gas development.
Human says the State and the private sector should urgently create collaboration structures to address imminent gas energy insecurity.
