PODCAST | Critical, but stable: unpacking SA’s precarious energy situation

Following the recent explosion at the Medupi power station, we discuss what the damage means for SA’s electricity generation capacity in this edition of the Business Day Spotlight.

Earlier this week, Eskom confirmed that Medupi — which had been completed only two weeks ago after years of being plagued by cost overruns, delays and design defects — experienced an explosion at the unit 4 generator. The incident occurred on Sunday evening and is suspected to have resulted in unit 5 tripping, said the utility.

The explosion resulted in extensive damage to the generator. No injuries have been reported and all employees and contractors have been accounted for.

Host Mudiwa Gavaza is joined by Dr Jarrad Wright, principal engineer at the CSIR, to discuss the implications.

Join the discussion: 

The Council for Scientific and Industrial Research (CSIR) is SA's state-run central scientific research and development unit.

Wright, a qualified electrical engineer with particular interests in power system operations and economics, talks to us about: how the explosion occurred; how much capacity has been taken out of Eskom as result; how does this affect the risk of load-shedding; what it will cost to repair the damage; the case for renewable and independent power production; and how Eskom stacks up against similarly sized power utilities around the world.
