Meanwhile in Germany:
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, 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
