There's not much hydro where I'm wrong, so I might be mistaken with this. But I always thought hydro was also pretty flexible, so it could serve as peak load? Like, you can even pump water up a dam if you have a surplus of electricity.

I am not sure about the speed, but the capacity is issue. It takes a lot of land to build a lot of hydro, damages ecosystems.
