I don't know if you crunch numbers but wind is joke compared to this project.  Maybe a 800MW dam.  Big turbines are lucky to average even close to 1MW actual output.  Probably less than that in most locals.  To get 1MW average output, you need maybe 3 or 4 MW nameplate capacity. Cost is maybe 2 million dollars per MW.  That comes to 800 machines of a 3MW capacity, each costing 6 million dollars. That's 4.8 Billion dollars.  And you would need a place to put them all.  And you still need the dam or power plant.  Or live in the dark when the wind slows.

I don't know if people want the power from this project, but if the do, it's either going to come mostly from hydro, natural gas or coal.
