I've seen their training videos... I found the one where they practice parachuting in and the one guy flying into rugby poles and knocking himself out very scary I'd have to run very fast from him!

I imagine if Koeberg wasn't undergoing such high maintenance it would be a different story. Some of our coal stations are basically dead though. If I had a tool that only worked 30% or less of the time I would throw it out and buy a new one. Sadly, you can't do that with coal power stations, but you get my drift.

Hendrina should be closed down, that thing is ancient
 
Get whoever is managing Matimba and Lethabo, to run some other power station.

Interesting enough Lathabo runs on very low grade of coal, I guess it can basically run on rocks :p

Lethabo burns coal with a calorific value of 15 - 16 MJ/kg and an ash content of 42%. It is the only power station in the world running on such low grade coal.

Lower grade, ideal for the average matriculate.

AFAIK, all our power stations except the 2 "new" ones medupi and kusile were designed to run on low grade coal so we could export the high grade stuff and use the other stuff that no one wants. This is the problem with medupi and kusile. AKAIK, the design was outsourced and used international norms and specced the boilers for normal coal instead of our unique stuff and now they don't burn properly. This is why our power was so cheap.

Divide by 3.6 to get kWh/kg
And finally understand why "I save so much using gas" fails the sniff test :)))...most of the time.

LPG max price currenty R32/kg on the coast (R34 in land). So LPG burned perfectly with no losses is 48/3.6 = 13kWh/kg
So it costs 32/13 = R2.46/kWh
