I see one of the options being considered to solve the electricity shortage is to introduce rationing.
South Africans could soon be faced with electricity quotas. Speaking to The Star on Sunday, Jacob Maroga, Eskom's chief executive, revealed that the parastatal was working on a plan which would see household and private industry usage being rationed.

According to Maroga, this ration would be calculated using an average consumption minus a specific percentage reduction.

Consumers who use more than their defined quota could face punitive costs or face being cut off.

Hmm. I wonder if Alusaf will attract a punitive rate?
