Sigh...:erm: ok, lemme try again.
Previously, if Eskom had a shortfall of more than 2000 MW they had to implement Stage 3 which freed an additional 2000 MW.
Now, lets say they were 2400 MW short. Implementing the old Stage 3 would have allowed 4000 MW to be shed, but since they don't need to shed that much it would have been overkill.
The new Stage 3 only allows for 3000 MW to be shed so that the 1000 MW saved can still be used by consumers.
Lets look at Cape Town metro for example:
The old Stage 3 would have affected 4 zones/areas concurrently. The new Stage 3 only effects 3 zones/areas concurrently.
Ergo, less impact on the consumer.
+1 for Eskom.
