>If a governmental agency is able to produce power at a lower cost than private industry - more power to them (no pun intended). I'd bet that when someone posts an example if we were to do a little digging we'd find that they a) didn't pay taxes when private companies do (unfair competition right?) or the land they own doesn't pay taxes or they spread the actual expenses around to cover or mask the real costs.

Not having to create a profit can drop cost dramatically.
