South Africa’s Integrated Resource Plan (IRP) 2025 promises to transform the nation’s electricity sector, prioritising renewable energy and gas while reducing dependence on fossil fuels. Minister of Electricity and Energy, Kgosientsho Ramokgopa, confirmed that, for the first time, clean energy will outpace fossil fuels, aiming to end load shedding and reduce costs.

Dan Marokane, Eskom Group Chief Executive, welcomed the plan, highlighting the utility’s role in providing baseload capacity to support renewable energy growth. 

“The IRP 2025 is not merely a policy update, it is a clear investment roadmap. It signals a focused pathway to reach Net Zero inclusively and provides the opportunity for Eskom to play its role fairly and compete in a reformed electricity supply industry.”

Professor Vally Padayachee, a former Eskom executive, emphasised the rationale for modular nuclear reactors and the transitional role of gas in the energy mix. 

“The potential reintroduction of modular nuclear reactors especially small modular nuclear reactors (SMRs) is a strategic decision rooted in the need for reliable, stable baseload power generation. Nuclear energy is also required to achieve these ‘green’ net zero targets.”

He added that gas, alongside wind and solar, serves as a necessary bridge in the country’s energy transition:

“The IRP's new emphasis on gas, alongside renewable sources like wind and solar, represents a transitional but necessary approach to energy generation in South Africa. In a context where renewables like wind and solar are naturally intermittent, gas serves as flexible backup power, helping to stabilize the grid.”

Padayachee also highlighted the critical role of private investment.

“Large-scale private renewable projects are pivotal in the successful realization of both energy and decarbonization targets in South Africa. By promoting private investment through incentives and a clear regulatory framework, we can unlock the financial resources needed for innovation and expansion in the renewable sector.”
