Enron energy traders called power plants and asked them to shut down during high load times. They encouraged the plant personnel to fabricate the reason for shut down. This created an electricity shortage, which forced rolling blackouts. Energy prices shot up, making for massive profits for Enron. There were also headline stories about elderly people suffering without air conditioning. The Enron traders joked about this in their phone calls to one another.

Of course, we only know about this because their phone calls were recorded. If I recall correctly, none of the traders indicated that they were aware their calls were recorded.
