Electric companies

Maybe some of our readers could help us out with why there generally is no choice for electric service in one's area they live. Only once have I had a choice to pick between companies for service. So since there has been a choice in the past, one can't argue it is impossible for two or more companies to send power over the same lines to your home or business.

But where I currently reside, there is only one choice. Without getting into the details of what has taken place, lets just say if this was a grocery store, or auto repair shop, I would never go back to them. But since it is the only electric service offered to my home, I am as it were stuck with them.

So any input?
