I've been very unlucky with PEPCO's service. In short, they are grossly incompetent.
I was lucky, however, to bear witness to this visual conflagration of their incompetence:
Its a video one of my neighbors took of the substation fire and collapse from earlier this week. It was very eerie, but it was beautiful, too.
It took Pepco two days to turn the power back on, and from what I've read, some people are still without power. For shame!
