s.80-IA(5): the initial assessment year and the notional brought-forward loss

My windmill ran at a loss for its first few years and I set those losses off against my other business income. Now that it is finally profitable and I have started claiming section 80-IA, the assessing officer says those old losses must be notionally brought forward and knocked off the windmill's profit, so my deduction is nil. Can he do that, and who gets to decide which year is my "initial assessment year"?
