Just checked with Lonmin and they in fact use electricity. And Eskom supplies them. They even have a customer number.
This is what I said:
You can’t compare mangoes to avocados. Large consumers such as mines or whole countries will always get a better rate than you, me or anyone else on a residential tariff.
Depends how they use the power. Large usage tariffs can be very expensive because they pay for stuff that small consumers don't:
- service/admin much higher in rands
- KVA maximum nominated demand - i e. Their max possible speed
- KVA Actual - their top speed each month
- power factor / reactive power
- even their kWh have at least 6 different rates (peak, stan, off high/low season)
Very very big users have the ability to only use in cheap times...and (i expect) employ people and processes to make sure they arent making silly decisions.
Sooooooo many commercial users do stupid things and end up paying R10,000s extra every month because they have a half hour in the month that their KVA is too high, or are simply on a poor choice of tariff or paying for capacity they have never and can never use...
