What a weird argument. If one doesn't trust private enterprise to "do right" then the state is nannying and oppressing companies, and if one does and therefore only inspects once a year or so then the state is neglecting their duties...
Public inspectors can't do right.
Maybe it is also fair to ask, did the developer/operator try to get away with something there? Do and hope for forgiveness instead of asking permission?
(and the "fine" is laughable, especially since retrospective permit is rather likely; in fact the fine might not even be higher than the cost of any project delay from requesting the generators at planning approval stage...)
