Rooftop solar panels are flooding California’s grid. That’s a problem. As electricity prices go negative, the Golden State is struggling to offload a glut of solar power (wapo.st)

I'll note that right now, this is a seasonal issue, associated with moderate springtime temperatures when there is a lot of sunshine available.

Yeah, it's not like it can't be saved in the brand new storage facility that happens to be one of the biggest in the world. This article reads like propaganda against solar.

It's existence highlights the need for more, and more distributed storage. That's a good discussion to be having

Relatively easy tech is temporary hydrogen storage. Of course hydrogen has poorer efficiency than batteries, but if all batteries are full, excess energy could be converted to hydrogen, stored, and converted back to electricity when no solar is available, and batteries are empty. Efficiency roundtrip with current tech is roughly 70%.
