> I will call out one thing for European readers. You’re suspiciously absent on lists of battery build outs. You guys don’t have lots or lobbying from legacy power providers wanting to maintain the ridiculously high peak prices by any chance?

The European power grid has multiple interconnections between the various countries, and some of those counties already have their grid scale storage (mostly pumped hydro). So it's much less needed.

So why would the countries heavy on renewables in their mix invest a lot in batteries? For instance the UK can rely on French nuclear and Norwegian hydro as a grid scale alternative source. While sometimes there are continent wide issues (we've had twice a month of low winds + overcast which impacted negatively wind and solar), the grid is sufficiently diverse and dispersed that it works pretty well.

As the recent outage in Iberia showed, it's slightly more complicated than that and batteries could still have a part to play to smooth demand ups and downs. And there are still a bunch of battery projects, even in France that doesn't have that much renewables in its energy mix, being heavy on nuclear.
