"The electricity department didn't roaster the electricity yesterday."
As we generally use the word "power Roastering"
Could it be "roster"? That means to schedule, although I can't really see how you can schedule electricity either.
I have just Googled the phrase "power roastering" as you said "we generally use..." but your question in this thread is the only Google result!
Can you actually explain what it means?
