Electricity and Control January 2018 OFCFiddling – while Eskom burns

Greetings to everyone from the Electricity+Control team and may it be a wonderful 2018 – all round!

No one wants to start the year on a ‘down’ … but how can the downfall of a once respected entity – Eskom – be ignored?

One of the many farces that exists in the organisation was highlighted on Twitter by civil activist and OUTA chairman, Wayne Duvenage, who points out that Eskom’s legal manager, who exposed alleged executive misconduct and fraud within the organisation, is being intimidated by Eskom; while executives with Big question marks over their heads have resumed their positions, employees having welcomed their return in song and dance.

  • Treasury has admitted that Eskom is the single biggest risk to our economy.
  • Eskom spokesperson, Khulu Phasiwe, himself, recently admitted that Eskom is facing serious liquidity problems and that it would be in ‘trouble’ if the situation got worse.
  • Piet van Staden (senior energy executive at Sasol, and past chairperson of the Energy Intensive Users Group (EIUG) of Southern Africa) refers to the situation as the ‘Utility Death Spiral’. He says that: “Eskom is deeply indebted, literally running out of cash, and needs to borrow about R60 bn per year for the next four years to finish the build programme. To add insult to injury, the revelations around governance and issues of state capture have left them with no friends”.
  • UCT Professor Anton Eberhard who, with Catrina Godinho, has published 'The Eskom Inquiry Reference Book’, posted on Twitter: “Minister Lynne Brown and the Board appear paralysed – either they don’t understand the severity of the matter or they don’t care – or both”.

To the President, the Deputy President, the government, the Eskom board, the singing and dancing employees, to ourselves, to me… can we simply stand by and watch?

Why are we Fiddling – while Eskom burns?
