But the quote literally spells out it was market forces, not some instability in solar generation?

Your other comment probably got flagged because it started with a huge straw man and had multiple unwarranted jabs in it.

Temporary negative prices have been caused by the renewable generation which exceeded the grid demand at the time, which then evolved into the nasty feedback loop caused by the reaction of renewable generation to those conditions. You simply do not get such situation with traditional generation, it's the direct consequence of the intermittent nature of renewables and its high ratio in the total generation.

Also, have you read after the market part? Please watch this video https://www.youtube.com/watch?v=7G4ipM2qjfw if the last quote is gibberish to you. It discusses somewhat different issues, but the point still stands.

Where is the market for someone to get paid to pump water into a reservoir and let it fall down later for $$$?

That market exists, but the window of time here is like twenty minutes. Pumps have inertia and take time to spin up, you can't HFT load and generation.

I'm not fully informed about pumped storage, but twenty minutes is more than enough for most hydroelectric plants to go from 0 to full power, and that's probably the case for pumped storage as well. Eg,

In the case of Cruachan Power Station: “It takes just two minutes for a turbine to run up from rest to generate mode,” says Martin McGhie, Operations and Maintenance Manager at the power station. “It takes slightly longer for the turbines to run down from generate to rest, but whatever function the turbines are performing, they can reach it within a matter of minutes.”
