Solar PV is probably the technology best suited to avoiding negative grid prices, if that is your goal.
It's sad that this scientific/engineering fact has been lost in the race to make dramatic headlines and climate denial propaganda.
Here we see it repeated by someone who seems genuinely positive about solar PV.
Basically, you need to shut off energy supply quickly and efficiently when demand drops. Anything with a giant spinning mass involved fails this test. If they have to keep steam hot they fail it even more. (Not to go on a tangent but this fast response is what the initial grid batteries have been getting paid for)
Of course, demand response systems have for decades paid people to shift demand towards the periods of cheap and/or clean energy because it is financially beneficial to the system. Any need that is met slightly earlier or later does not need to be met with more expensive and/or dirtier fuels. A simple system optimisation.
Apply that to a predictable supply of cheap clean energy in a market based system and suddenly you have the "problem" of people being incentivised with money to use energy when it is available.
What a tragedy, who will save us from this cheap clean energy that is going to destroy the grid with the evil magic of negative numbers.

- ZeroGravitas 2y agoIf you wanted to use solar PV as an energy sink, which you don't, that would also work. PV panels are LEDs run in reverse. I believe part of the QA process for some panels is to run them in reverse and take an IR photograph of the output to check for defects.
