No, the cost structure of fusion is going to be much like fission: the cost of building the reactor has to be spread over time (with interest). Even though the fuel is cheap, you are (in a financial sense) 'burning' the reactor, which is expensive and must be bought up front. We don't know for sure how it will work out, but none of the predictions I've seen show fusion producing dramatically lower cost of electricity.
