Dave, I agree in principal, but taking the load-shedding into account, if a company has to work that into a pre-build budget and have the possibility of losing millions from a Single-point failure(ie Eishkom), I still reckon it's a more viable option, at least for companies in SA now and over the next few year.

Yes, there is more capital layout from the start, there are more management decisions to be made and handled on a day-to-day basis, but facing the very real possibility of having to shut down your plant, costing you $50mil losses per hour, the capital spent on putting your own backup solution in place starts sounding like a good idea...

Couple that with the fact, bearing SA Goverment not getting their knickers in a twist, that agreements could be made with Eskom in order to sell the excess or unneeded power back to the grid, the 10c versus 12c situation is starting to look a lot different.
