I dont know the exact numbers, but when I upgraded from 90 to 180, the bill didnt change all that much (maybe $10-15), even though I went from an internal pump and powerheads, to 2 externals and a closed loop + the extra light.
My air conditioner has far more of an effect on the bill than the fish tank does, thats for sure.
