You’re describing dams, and basically all the good locations are taken already.
No, he’s describing a pumped storage facility.
Tbf that would be two dams and they did use the plural of dams, technically ‘dams’ could be a pumped storage facility.
To be even fairer, his central point that “all the good locations are taken already” only applies specifically to the regular type of dams that don’t use pumped storage. For traditional hydroelectricity you need an easily-dammed-off hilly basin containing a large/high hydraulic head river, but for pumped-storage you just need the hilly basin.
