The uniqueness of this project lies therein that Medupi is being constructed in reverse sequence, the opposite of the traditional Eskom practice of starting with Unit 1 and ending with Unit 6. This distinguishing approach is the result of the rock conglomeration on the southern side of the site which was excavated and reused as engineering fill on the northern side.
Medupi is also built ready for the installation of abatement technology such as flue gas desulphurisation which will reduce Sulphur Dioxide (SO2) emissions by over 90%. It will also include pulse jet fabric filters, which will remove approximately 99% of particulate matter, and low NOx burners that reduce nitrogen oxide emissions. All of this will have an effect of reducing the environmental impact on ambient air quality.
Medupi Power Station leads the fleet to implement lining for its ash dams and coal stockyards. The power station will operate under Zero Liquid Effluent Discharge (ZLED) principles meaning that all treated effluent generated by the power station will be re-used and not released to the environment. The planned operational life of the station is 50 years.
