Yes, it is. Obscenely so. Why are you comparing it to a tank of gasoline MPG? It's not gasoline. Compare it to how much you can buy a KWh from the local utility company. This would be the profit equivalent of a gas station charging you around $15 for a gallon of regular.
EDIT: You know, now that I think about it, they are selling power to the public. Why do they not have to abide by the rates set forth by the PUC (OUC)?
