PSNH would have considerably more "wiggle room" to work with ballooning costs, given that they would "cut out the middle-man". I don't remember what the amount of power generated in the PPA is, nor do I know what the rate to buy electricity is around there, but I suspect that there is plenty of potential profit (or cost savings) for PSNH to own the plant. I'm guessing that the $1.3B that PSNH would pay per the PPA pales in comparison to what the customers pay PSNH for the same power. That is where PSNH makes their profits. Any profit that Cate Street, LLEG or any other owner would get, diminishing tho it may be, is still additional profit to PSNH.
