Actually I need to side to some degree with those who think it should be nationally owned.
There DOES need to be some oversite for services, which is lost, would cripple or even destroy the nation. Power is one of those things, which if we don't have, we become our great grandparents again very quickly in terms of abilities (only without their knowlage of living without power). As such 100% private controlled is bad. There needs to be SOME regulation such that no one can turn off the lights on a whim, or due to poor management. Just like its illegal for air traffic controllers to strike, you need SOME sort of assurance that everying will keep working.
Now where I would differ is the extent of government control. I'm much happier with government oversite of a private company, then a government owned one. A private company as a rule will work harder, if you don't believe me, work in government a bit, and will see benifits of making the public happy with their service for the most part.
Ok its late, and I can hardly see so this will have to do, typos and all
