There's the externality of pollution you didn't consider.

  That's true, but how much pollution does it cost to replace the generator?

  Since the generators apparently run less efficiently at partial load, that's not a given either. They'll almost certainly produce more pollution per unit fuel. Hm, is that a few percent more, or a few times more?
