As Southern Africa’s leading economy, South Africa should evaluate the development of gas-to-power projects to address climate change, increase its power generating capacity, and stop load shedding, which represented an estimated loss to the South African economy of R338 billion over the last ten years, according to Business Tech.

Such power projects could be fuelled by liquified natural gas ("LNG") considering sub-Saharan Africa's significant natural gas resources, which remain underexploited. Such projects could be the key to transformative change, by making available reliable energy for growth and industrialisation at affordable rates, something that South Africa has been looking for a long time.

However, this will not be an easy task as South Africa's demand for affordable and reliable energy is expected to multiply multiple fold, considering its relatively young population, standing at a median age of 27.6 years and rising urbanisation.

The South African government needs to elaborate energy plans for the next 50 years to keep the economy growing and meet the anticipated growth in demand. If that does not happen, South Africa will not only fail to stop load shedding, but the system may deteriorate under the weight of ever rising demand, leading to longer blackouts.

Load-shedding concerns

South Africa has mainly utilized coal power plants as its primary energy source; however, meeting the supply has been challenging to the government as the demand for energy increases. Regularly scheduled mandatory load shedding started in 2007 to allow maintenance periods of power generators and recovery of coal stockpiles before the winter when electricity usage surges. It has been 13 years of the same problem with no practical solution on sight.

According to a Public Servants Association (PSA) document published in 2015, South Africa's grid has inadequate capacity to operate within reasonable operating buffers due to overworking of aging power stations, triggering failures, and sparking load-shedding. The roots of the crisis lie in insufficient investment in new generation capacity.

What is the country doing?

With the introduction of load shedding in 2007, the government took swift action by announcing a costly overhaul of two power plants, Kusile and Medupi, which were meant to become fully operational by 2015; however, the construction was set back by spiralling costs, delays, and corruption scandals. Eskom informed the public, that the first unit of the Kusile power station was connected to the national grid in 2016, adding 800MW to stabilize the power system.

 Kusile unit 2 achieved commercial operation on 29 October 2020 and  Unit 3 in March 2021, while Medupi Unit 1 will achieve commercial operation by July 2021. According to Eskom, Medupi Unit 3 reached its full generation capacity (793MW) in April 2020. The unit has completed seven consecutive months of improved performance since.

The government launched the Integrated Resource Plan for electricity ("IRP") in 2010, which was later replaced by an updated version in 2019.

The IRP 2019 proposes to add 39 696MW by 2030 to the national grid, including power generation by independent power producers ("IPPs"). In such regard, the government launched the Independent Power Producers Procurement Programme ("IPPPP") and the Renewable Energy Independent Power Producer Programme ("REIPPP"), with the target of producing 17 800MW by 2030. The REIPPP has procured projects from four bidding rounds, with the much-expected fifth-round launched in April this year.

Furthermore, under renewables, the government has also been exploring generating electricity using solar energy, which also falls under the REIPPP.

 According to government's information, the program aims to bring additional MWs onto the country's electricity system through private sector investment in wind, biomass, and small hydro, among others. However, as much as it serves as a tool to bring additional megawatts onto the country's electricity system, it is unlikely to be the silver bullet, as photovoltaic devices die out after 20 years, need to be replaced and require a backup energy source for the grid.

LNG-to-power can help South Africa meet its growing demand

The aim of transitioning to LNG-to-power is to change our old way of generating electricity and change together with the rest of the world as we transition to a cleaner way of generating electricity.

LNG-to-power could be used in South Africa to generate cheaper, reliable electricity. As an abundant energy resource, natural gas may meet the demand for electricity of the growing population in the country. Natural gas can be used to generate electricity, as fuel for industrial processes, for heating, and as a raw material to produce chemicals, fertilizer, and hydrogen. It can also be used in the residential, commercial, and transport sectors in several applications.

LNG is the cleanest fossil fuel in the context of energy transition, it represents an excellent alternative to reduce greenhouse gas emissions and help combat global warming. As reported by ‘Elengy’- an LNG expert company, the combustion of natural gas does not emit soot, dust or fumes. It generates 30% less carbon dioxide (CO2) than fuel oil and 45% less than coal, with a twofold reduction in nitrogen oxide (N0x) emissions and almost no environmentally-damaging sulphur dioxide (SO2) emissions.

The South African government should focus on developing gas-to-power projects, especially considering the recent Brulpadda and Luiperd gas discoveries. According to Cliffe Dekker Hofmeyr, the discoveries of gas condensate fields during 2019 and 2020 are significant, and they have the potential to expedite the government's much-touted energy transformation. While studies are still being conducted, early estimates are that the two gas fields may hold over 1 billion barrels of gas condensate each. If these estimates are accurate, these discoveries would be huge for South Africa as a non-producing country heavily reliant on oil and gas imports.

Post-Covid-19 will see a more robust influence on the global energy market and the phase of transition. Decarbonization will shift the energy mix at an expeditious pace and is expected to place gas ahead of coal by 2030 to become the world's number two fuel, with oil remaining in the top position.

Where is the LNG coming from?

Among the magnificent discoveries over the past decade is Mozambique's natural gas, estimated at over 180 tcf (trillion cubic feet), which has already unlocked the first three large-scale LNG projects. Together with project expansion phases and additional exploration, these projects can position Mozambique as the third-largest global LNG producer after Qatar and Australia by 2030.

Natural gas is becoming more significant to the region's energy sector as Mozambique, Namibia, South Africa and Tanzania develop natural gas fields in their respective countries.

Being a neighbor to Mozambique, South Africa is perfectly positioned to transport LNG as the country's short shipping distances from Mozambique to the Durban basin will help favourable delivery prices. In an article by Charne Hundermark, she highlights how South Africa may receive the LNG by developing a cross-border pipeline – the African Renaissance Pipeline Project – which aims to connect Mozambique's massive reserves with South Africa's growing energy demand. The pipeline will offer a direct export link to South Africa, capitalizing on the country's demand and providing sub-pipelines to branch off of the main one and connect to other countries, such as Zambia Zimbabwe.

The SADC region contains 9.2 trillion cubic feet (Tcf) of proven natural gas reserves. The majority of the proven reserves are located in Angola (11 Tcf), Mozambique (100 Tcf), Namibia (2.2 Tcf), Tanzania, with 57.5 Trillion cubic feet (Tcf) and DRC (0.04 Tcf). Overall, the region contains approximately 1.9 percent of Africa's natural gas reserves. Several projects are underway to expand utilization of natural gas in the region. Energy Ministers approved in 2018 the development of the SADC Regional Master Plan covering evaluation of the available gas resources and existing markets, gas utilization strategy, supply and demand analysis.

Mozambique and Tanzania gas resources, in particular, are well-positioned for cross-boundary development of gas pipeline infrastructure. Gas demand in the region must be serviced from regional gas resources to increase the opportunity for intra-African trade and economic collaboration. While the infrastructure for the transport of LNG is currently unavailable, its commissioning is the safest and easiest way to transport the natural gas once in place.


One of the biggest challenges facing LNG projects in the continent is the lack of established infrastructure and logistics. According to the National Energy Regulator of South Africa, the limited transmission and distribution infrastructure for gas and the relatively limited availability of gas are responsible for a slow uptake in South Africa. Additionally, South Africa needs to develop the energy industry to boost the economy and eliminate energy poverty/insecurity by developing gas to power infrastructure.

Gas must play an important role in the energy mix going forward if South Africa is to meet its economic, political and social objectives of reducing poverty, reducing inequality and raising the standard of living of all its citizens. The global transition to cleaner energy, coupled with the oversupply of fossil fuels, price volatility, and cost pressure, have made private and public sector oil and gas players rethink their business strategies. It is in the country's best interest to step up and jump in the moving train towards increased natural gas use.
