First, the limitation is both directions which is part of the story that made Susitna such con job - the Kenai would not have benefited much if at all from that proposed project. Second, if there is politics, pray tell what that looks like.  Whose ox is either going to be gored or fed by sticking with the status quo or upgrading the intertie?  Reading the silence from CEA, ML&P, MEA, et al on Susitna I was pretty sure they were not fans. And it made sense, they each had new 100++ MW plants either just coming on line or in construction, 50% of Watana capacity that was going to be diluted.  And yes, I realize politics or reality is involved in these ops, I was more deeply involved with Terror Lake that had some capacity constraints due to fish of all things.
