Yes they do, like all energy sources there's a physical limit on how far you can transmit it, all power generators live in a regional bubble.
There's a reason all that excess hydro energy in Sichaun province goes into negative prices multiple times a year and can't be bought elsewhere in the country or even exported to other countries, it's simply too far away.

- BelenusMordred 6y agoThat's the longest in the world, not exactly representative of the norm. There's grid bubbles everywhere, they do all live in a "vacuum", you can't just magically transport it without decades long mega infrastructure projects to build super grids and accepting large transmission losses.
