Energy Exchange of Southern Africa (EXSA), which has support from Remgro, is working with Engie Energy Marketing South Africa to obtain new electricity licenses. One of these licenses is for electricity trading, and the other is for energy transmission across regional borders.
The energy regulator Nersa will consider both applications during a virtual public hearing scheduled for December 7, according to a notice on its website.
Engie Energy Marketing South Africa applied for an electricity trading license covering the Eastern Cape and KwaZulu-Natal provinces, where power is supplied by Eskom. As for EXSA, it is applying for an import-export license valid within the Southern African Development Community (SADC).
The French energy group Engie operates the Avon and Dedisa peaking plants. These plants combined can supply 1 GW to Eskom under 15-year agreements. The Dedisa plant is located in the Eastern Cape, and Avon in KwaZulu-Natal, corresponding to the two provinces mentioned in the trading application. Engie, formerly known as GDF Suez, acquired a 38% stake in both projects along with Legend Power Solutions (27%), Mitsui & Co (25%), and The Peaker Trust (10%).
EXSA was established in 2017. In 2023, Remgro sold a 25% stake in Rand Merchant Bank (RMB), and in 2022, EXSA obtained a Nersa license for electricity trading within the Eskom network, as stated on its website.
EXSA will not be the first private trading company to receive approval for cross-border energy transmission. Polity reported that Nersa granted GreenCo Power Services the country's first private import-export license in October 2024, and Green Building Africa noted that Enpower Trading received a similar SADC-covering license in 2025.
Applications amid trade regime uncertainty
Last week at the University of Witwatersrand Business School, Minister of Energy Kgosientsho Ramokgopa stated that neighboring connected regions face a deficit of about 6 GW, while South Africa has an average surplus of about 4 GW. However, exports will only be possible after domestic demand and reserves for growth are secured. He emphasized: 'Before thinking about exporting electrons, we must be sure that we can meet our own demand.'
The Minister also cautioned against rushing into the wholesale market, stating: 'I warn that the speed of our entry into this market must be carefully measured.'
These applications come at a time when the trade regime remains uncertain. Eskom has taken legal action to review five trading licenses issued by Nersa to Green Electron Market, CBI Electric Apollo, GreenCo Power Services, Discovery Green, and Noa Group Trading, claiming they allow new participants to avoid participation in subsidies. EXSA's license was not included in this list.
The case was previously suspended earlier this year to allow Nersa time to finalize trading rules, which are still under development. In a joint statement in February, reported by the African News Agency, Eskom and traders stated that this was 'not a withdrawal of the review application, but rather a procedural suspension.'
The licensing hearing will take place from 9:30 to 13:00 on Microsoft Teams. Anyone wishing to participate or submit comments must register by 16:30 on November 30 via publichearings@nersa.org.za.
Rules for private grid builders
On the same day, from 14:00 to 17:00, Nersa will review comments on the draft revised cost reimbursement rules for Independent Transmission Providers (ITPs)—private companies designed to build and own new transmission lines. These rules define how they can compensate for their investments. The deadline for submitting written comments is December 2, and they can be sent to crr4itps@nersa.org.za.
The first phase of the ITP program involves building 1,164 km of new lines. On October 1, the National Treasury and the Department of Energy and Electricity postponed the final request for proposals to the second quarter of 2027, including Nersa among the organizations handling remaining commercial, regulatory, and financial matters.
CEO of Business Leadership South Africa, Busi Mavuso, warned that 'at the current trajectory, new grid infrastructure is unlikely to start operating by the end of the decade.'
