Minimum Emission Standards applications
Eskom believes that the applications are appropriate for a number of reasons which are described in the applications, and key reasons include:
- For Acacia and Port Rex the suspensions and alternative limit request will have limited air quality impact given the very low use of the station (generally less than 1 day a year), the intent to close the stations by 2030 and the cost of the upgrades to enable compliance, estimated as in excess of R100 million.
- Compliance upgrades at Grootvlei Power Station would cost in excess of R11 billion and for a station which is scheduled for decommissioning by not later than 2030, and given the limit air quality impact, full compliance to the MES is not seen as appropriate.
- Medupi Power Station will comply with most of the required emission limits, however the Flue Gas Desulphurisation (FGD) project which is required to support compliance to the Sulphur Dioxide limits is behind schedule and Eskom has requested alternative limits until the project is completed by 2030, and thereafter until decommissioning.
- In order to support meeting the Sulphur Dioxide standards in particular, FGD would be required at Matimba Power Station. Eskom does not believe that given the limited air quality impact and considering the significant volumes of water required, the additional waste produced and a cost of between R15 and R26 billion for FGD, that installing the technology is appropriate for Matimba. Eskom is thus requesting an alternative limit for Sulphur Dioxide for the station.
The public participation process for the Medupi and Matimba applications have commenced and will continue in early 2020. Public participation processes for Acacia, Port Rex and Grootvlei will begin early 2020. Stakeholders will be informed of these processes through the media and emails. The inputs from the public participation and updated technical studies will be provided to the authorities as additional information into the applications submitted in November.
In terms of legislation Eskom is required to vary the stations Atmospheric Emission Licenses in support of the MES application and details of the variation are provided on the links above.
