To be totally clear, I don't care about the people or the local environment there, and I do think the renewable power generated by hydro is a great current and future source of electricity.
With that said, I can still be against it if the numbers don't work.

The big factor is what you think interest rate is going to be on this plant.
5,100 GWh is worth a lot. Depending on your power prices, $250M to $300M per year. ($50K-$60K/GWh).
Wind is getting down there in cost, but storage is very expensive. I don't know how many days storage is needed if we stop building dams, but it will increase pretty significantly after a while.
Overnight storage essentially doubles the power of solar power right now for off-grid applications in sunny climates. The batteries will get cheaper, but the bigger gaps you have to fill in with intermittent supply the larger the cost is.
