Another area that may be valid for pumped storage in the Tennessee Valley.

Many of the depression-era dams will need to be replaced as the underlying limestone rock is slowly dissolving. Instead of one simple hydro plant, build two with somewhat lower head to extend support strata life.


Making pumped storage sites is less wasteful than simply draining and destroying the existing sites.


BTW, on energy, I am 100% in the "all of the above" camp. Everything has a role to play.
