I wouldn't sweat the cost too much. The Dams on the Columbia are run by the Feds. If the Feds drop their funding for the dams you'll actually have to start paying to run the dams as well as for the cost it takes to transmit the electricity. If you don't know the Feds are going broke then you aint been payin attention. We can't ride 9.5 cents per Kilowatt Hour gravy train we have been on forever. The electricity is needed, the impact is minimal, greater access to the public (hopefully) will be created, a series of falls will be dewatered making them easier to fish and finally the Sunset falls fish trap will have eternal funding so long as the powerhouse exists. FYI, you aren't going to stop this project. You may as well confine your thoughts and comments to how you want the facility to be setup to benefit you instead of feebily fighting it's construction.
