Forestry, Fisheries and the Environment Minister Dr Dion George has granted Eskom air-pollution exemptions for eight power stations that would otherwise have been forced to close on April 1. He insists, however, that the exemptions do not represent a "blanket reprieve" and that they have been granted together with "rigorous conditions".
On December 10, Eskom applied for relief from the minimum emission standards (MES) for eight of its coal-fired power stations, namely Duvha, Kendal, Lethabo, Majuba, Matimba, Matla, Medupi, and Tutuka.
The applications were made in line with Section 59 of the National Environmental Management: Air Quality Act, 2004, and followed the granting last year by George's predecessor, Barbara Creecy, of permission allowing Eskom to continue to operate the aged Hendrina, Grootvlei, Arnot, Camden and Kriel at existing MES plant limits until their decommissioning on March 31, 2030.
The decision of both Ministers followed an intense period of electricity insecurity, with loadshedding, which has been a persistent threat since 2007, having intensified to the point where it was being implemented almost daily in 2023.
There have also been bouts of rotational power cuts in the early months of 2025, despite a material waning of loadshedding on the back of coal plant improvements following a big taxpayer funded debt-relief programme at Eskom, as well as significant private investment in solar PV and batteries, which has helped reduce demand and create space for much-needed maintenance.
On March 31, George announced his MES decision, which he said sought to balance the imperatives of energy security, economic stability, and environmental protection.
During a briefing in Cape Town, he announced that two of the stations (Duvha and Matla) had been granted exemptions until their decommissioning date in 2034.
The other six, were granted five-year exemptions until April 1, 2030, during which time actions would need to be taken to mitigate their pollution and to prepare the stations to operate legally thereafter.
KEY CONDITIONS
Some of the near-term mitigation actions ordered, included:
The deployment of air quality monitoring stations and a data-free alert App within eight months;
The appointment of an environmental health specialist within three months, and the extension of health-screening programmes within six months in affected communities, alongside mobile clinics and greenspace initiatives;
The expansion of interventions to 96 000 households within 12 months, while addressing waste and ash dumps near power stations;
The immediate publication of real-time emissions data, with additional monitoring stations to be installed within 12 months;
The completion of a revised cost-benefit analysis within six months regarding Medupi's delayed flue gas desulphurisation (FGD) retrofit; and
The publication by the end of March yearly of a detail report on what progress Eskom was making to integrate renewable energy into the grid.
George even went so far as to suggest specific energy policies that he said required priority if South Africa were to transition to a point where there would be security of supply, while also meeting the obligation outlined in Section 24 of the Constitution guaranteeing a right to an environment that is not harmful to health and well-being.
Some of his recommendations included transitioning the Independent Power Producer Office into an independent Transmission System Operator to streamline procurement; accelerating transmission infrastructure under the National Transmission Company South Africa to facilitate seamless grid integration of renewable projects; and the establishment of a competitive power market by April 1, 2026.
WHAT HAS BEEN GRANTED?
Meanwhile George also outlined the following specific decision for each of the affected coal-fired power stations:
An MES exemption for the Duvha power station until its planned decommissioning date of February 21, 2034, alongside conditions for mitigating t...
