Does Belgium (OPs example) have the geography necessary to support pumped hydro? Your example, Switzerland, is significantly more mountainous than Belgium.

Wallonia has at least one pumped hydro that I know of.

There were plants for a 'energy island' 300MW hydro plant at sea, near the large-scale wind farms. The idea is the same, pump sea water up an artificial horse-shoe shaped island. A nice bonus is that you can play with the tides as well. The height difference does not have to be great, if you can compensate with a large surface area.

As far as I know, those plans were shelved. A quick googling says that similar concepts are being considered for interconnected dutch/danish wind farms.

It has 1164MW capacity, with ~1000GWh/year supplied.

I know of at least one pumped storage dam in Belgium, in the mountainous southern part (Wallonia)
