Electricity? Like, you use excess power to lift water and generate power from letting it descend when you need power. The latter is generated. Or am I not getting something?
I know. It never generates more than it consumes so it has negative production overall. Or is this a real-time chart despite saying “past 12 months”?
"consumption takes imports and exports into account, production ignores them"

I think the idea is that it only uses excess energy that would otherwise be wasted to fill it, so it kind of generates energy as it's essentially filled for free.
Yes, I know. Still, misleading: they show up negative in these power generation charts most of the time and this is supposed to be a cumulative one.
Rain fills them without consuming energy
Yes, they are part of the water cycle, sometimes collecting water from a significant area, but usually not. This is the upper reservoir of our largest hydro storage plant:
Rain is only collected over the area of the reservoir, and it would only fill up a few centimeters on a rainy day. In fact, the water evaporates quicker than that so a lake would never naturally form in this location.
Are all hydro storage like that though? It doesn't seem too outlandish to think of a hydro storage plant that is also fed by a river
I mean, at that point you would just call it a hydro power plant. Pretty much all hydropower doubles as storage due it's flexibility, but typically don't bother pumping water back up as it's a waste of energy (as opposed to waiting for the river to do it's work)
