Brilliantly researched and written. Having lived in SA and worked with ESKOM and Koeberg specifically throughout the 80‘s through the early 2000‘s, I have experienced firsthand the incredible work done by the very well educated and experienced personnel within ESKOM and their commitment to lead a world-class utility. Sad days to see what has happened since. Maybe there is still hope for a turnaround - see https://m.youtube.com/watch?v=be4vChJ3E1s

Adam, you have done your homework well! Having worked with both ESKOM and NERSA as an external advising basis during the 2000-2007 period you have brought back of flood of those memories with your piece. I hope you had the opportunity to meet with professor Anton Eberhard who has been working in power sector reform for the past 30 years or longer during your visit to UCT.

In my experience, ESKOM had the technical skill and personnel to make change happen. What they and the unions and government lacked was the ability and desire to change as you clearly articulated. ESKOM at its core was and is culturally and monopolist. Monopolists block entry and change for fear of loss of status or their jobs! The same is true with the unions. The fear of loss meant they’d hold on to coal for as long as humanly possible because of perceived job losses and social dislocation and encouraged by the unions, and because ESKOM lacked any imagination on operating any other kind of generating technology.

Add into it, my perception that if they allowed new generation to interconnect they would now have to think about the transmission system as a truly meshed network with power flows that went against their entire experience.

As somebody who has worked in power systems for more than 25 years, the ESKOM system operates radially like a hub and spoke network with the hub in the NE centered on the Mpumalanga coal fields and radiating out to from there with the longest lines reaching the western cape where Koeberg was located. When Koeberg went down, it was difficult to support power transfers due to long lines, lack of voltage support, and in reality was single point mode of failure if any of the transmission line tripped or were taken out of service.

Your mention of Zuma’s boondoggle on 9 GW of nuclear had its start in Eskom’s fixation with pebble bed nuclear technology that 25 years later still has not seen the light of day, and insistence on my 7 years of discussions was that it was just around the corner. We see the same today with modular reactor technology in the US. But given the fixation with “6 packs” or 6 600 MW unit coal plants and pebble bed nuclear, the imagination and innovation simply left the collective mind.

And while South Africa did not have meaningful access to natural gas, for years there was the possibility of gas E&P of the Atlantic coast off Angola and Namibia or Mozambique on the Indian Ocean side. Clearly nothing came of that and this the huge boom in technical improvements in efficiency and cost savings seen in gas turbine technology that started 20 years ago have passed the country by.

Finally, and maybe something for further exploration, is the outsize role that ESKOM played in the Southern Africa Power Pool (SAPP). You mention the imports from Namibia and Zimbabwe only in passing. At one time this was one of the more sophisticated power pooling arrangements in the world. Now it has become moribund. ESKOM had the coal, other countries had the hydro. There was once cooperation in operations and planning. And there were big dreams, that while nice on paper, would never be realized but this also stymied thinking beyond what was in front of ESKOM. They already had access to Cahora Bassa in Mozambique, though the colonial past surrounding it is not pleasant, and dreamed of tapping hydro potential in Angola (all they have gotten was good Cuban food, music and culture instead). Such projects are overly grandiose and avoid the hard work of manage power system planning, operation and control and doing what is feasible and needed in the short to medium term.

All this being said, South Africa and ESKOM need fresh, innovative thinking, toss out the old ideas, and begin thinking in the near term with no regrets as the point of departure for a strategy to get out of this mess. But the necessary condition is to change the political and corporate culture of ESKOM and the unions and get them to see their fear of loss will only beget further loss.
