GE released a paper sharing their position on South Africa’s energy transition and the role they believe gas power and renewables will play in accelerating the country’s energy transition.
As South Africa is addressing climate change as an urgent priority with strong commitments on policy and regulation, GE shared its position that the accelerated and strategic deployment of both renewable energy and gas power can make substantial progress in combating climate change in the near-term, while securing a path to a lower-carbon emitting world in the future.
In the newly published position paper, titled Accelerating South Africa’s energy transition with gas power and renewables, GE said neither power source will be sufficient alone, but when deployed in tandem can provide decarbonisation at the pace and scale needed to achieve substantial climate goals.

“A combination of renewables and gas power will be the fastest and most cost-effective pathway to decarbonisation for South Africa,” said Elisee Sezan, CEO for GE’s Gas Power business in sub-Saharan Africa. “Reliable gas technology solutions and renewable energy sources will make investments economically sound for immediate emissions reductions and we believe that gas will not just be a backup fuel but will be the new baseload capacity for the coal repurposing national programme.”
According to the whitepaper, affordable, reliable, and sustainable electricity is South Africa’s most urgent need. About four to six gigawatts of power is needed in the near term to ease current electricity constraints and the country aims to add about 20GW of additional power with renewables and gas in the long term.
Research shows South Africa’s energy mix will evolve to include greater amounts of renewables, even as coal remains the dominant fuel beyond 2040. GE believes in and promotes additional renewables capacity, augmented where needed with gas generation to provide system flexibility and dependable capacity, as the most effective near-term action to decarbonise the energy sector. Given the time it takes to deploy new renewables and to implement energy efficiency improvements, coal-to-gas switching represents a potential quick win for emissions reductions.
“Retiring aging coal-fired capacity and replacing it with new, high efficiency combined cycle gas power technology would almost immediately bring down power sector emissions and total energy-related carbon emissions,” said Nosizwe Dlengezele, GE Gas Power’s chief commercial officer, sub-Saharan Africa. “Case in point, GE’s HA gas turbine portfolio offers record levels of more than 64% combined cycle efficiency, fuel flexibility, and the capability to transition from gas to low-carbon fuels such as hydrogen, and this positions the HA gas turbine as an ideal fit for South Africa.”
In South Africa, coal-fired plants account for 84.5% of total carbon emissions and the move to a more diversified fuel mix will see a drastic reduction in the carbon footprint of the country. By 2030, South Africa aims to reduce its annual greenhouse gas (GHG) emissions by 28% less than its 2015-set targets in the updated draft of the Nationally Determined Contribution (NDC) and become a net zero economy by 2050.
The paper notes that the timing is right for South Africa to implement its Gas-to-Power programme, as reliable power is a prerequisite for economic development and many industries are deeply affected by power sector inefficiencies. Due to its competitiveness and bankability either as a bridge or destination fuel, the paper views Liquified Natural Gas (LNG) as a fuel of choice for decarbonisation in countries like South Africa without adequate commercial gas reserves, and the introduction of new LNG supply is a critical first step in developing the Gas Master Plan.
GE also highlights the need for solid collaboration between the private and public sector to help ensure effective implementation of projects end to end, as well as extensive gas policies and developmental goals to ensure the country reaps all the benefits it comes with.
