The situation is getting complex in the U.K. too. The deregulation of recent years means that you can buy your electicity from a variety of companies. I might be in East Anglia (East of England), but if I wanted I could contract with Scottish Power for my energy. Similarly, if I were to move p to far north of Scotland I could still keep paying TXU Energi (which took over Eastern Electricity a while ago) for my electricity.
It's all become quite bizarre; after all, the stuff still comes along the same cables as before.
