Where was Eskom during the Live Earth concert?

With all the power capacity problems that we have and are experiencing with Eskom, I was amazed that they did not take any advantage of the "Life Earth" concert message. Why not or did I miss it :)?

Surly this was a great opportunity to “ride on the back” of this concert and spread the message to South African power consumers to be more conservative and aware with their power usages.

Seems like a missed opportunity. Eskom where were you?
