Meanwhile in Germany:
Consumption by source
Weird way to put it… also wtf is hydro storage generating?
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.
I’ve been to a hydro storage plant and I know how it works. It stores power by pumping water into an upper reservoir when there is excess power and then letting it through turbines at peak demand. Overall, it achieves about 80% efficient energy storage whose capacity scales very cheaply as opposed to battery storage, and can respond to demand in a minute.
However, it never generates power in the usual sense so it should show up negative on an overall chart. Is this a real time one? I don’t think so because it says “past 12 months”.
Could a dam lake be counted as hydro storage? That wouldn’t require energy spending to pump water up, but it can work as a “cache”?
