Why not do something with all that power? In the past there were some projects where they pumped water upstream when there was too much power on the grid. Then on low energy times, the water was released making energy again. Or make hydrogen (I think it was hydrogen). Or do AI stuff
I also seen energie waste machines that basically use a lot of power to do nothing. Only the get rid of all that extra energy so the power grid won't go down/burn.
Why not do something with all that power?
This is a relatively new problem, so it will take awhile for the market to respond to make industries optimized to take advantage of this.
I saw an article a few months ago (couldn't find it quickly just now) about a small manufacturing company (metals maybe?) that set up shop specifically to run during the excess power events. So its starting to happen, but its not going to be a perfect fit. It means spending lots up front for infra, but only being able to use it a few hours a day cost effectively.

This is already done with pump hydro. But this needs existing hydroelectric infrastructure to take advantage of. Even then there are usually holding ponds upstream and they themselves have limited capacity.
Or make hydrogen (I think it was hydrogen).
This is being done too at small scales right now. There's difficulties with it. Hydrogen really sucks to try store and transport. The H2 molecule is so small it leaks out through valves and gaskets that are fine for containing nearly all other gases and liquids. So this means the gear needed is hugely more expensive up front. What a few are doing is using the hydrogen to quickly make Ammonia (NH3), which is much easier to store and contain. However, the efforts doing this are still fairly small.
Or do AI stuff
AI aside, this is one place I haven't seen develop yet. That being: cheaper compute costs during excess power events.
I suspect its the same problem for the manufacturing. It means spending money on expensive compute infrastructure but only able to use it during the excess power events. As in, the compute in place is already running flat out at full capacity all the time. There's no spare hardware to use the excess power. If you had spare hardware, you'd add it to your fleet and run it 24/7 making more money.
Or use it on large scale computing for protein folding simulations, or something.
And yeah, gravity batteries is the best I think we have, with water being the most common medium with pumped-storage hydroelectricity. But the scales of the things are kind of incongruent and... Autoincorrect actually got it right trying to correct that to inconvenient. Still really cool. I think we may need some innovations to cut down on scale issues though. Although it looks like the total power storage available is about one day worth of power for the US in PSH, I'm curious if the instantaneous output is sufficient for the grid and how spread out the storage locations are, as I somewhat doubt they're often in flatter regions. All in all, I'm not a power engineer, I just know a few and I should bug them sometime.
Just install a bunch of spotlights that point back at the Sun so when power prices go negative you can return all that excess energy! Come on MIT, I thought you were supposed to be smart.
Wasn't there a town in China that produced such a glut of surplus electricity that they didn't know what to do with it? And it was 100% solar?
I get the sentiment but... When sun isn't shining the negative prices cause problem for baseline power producers who need to turn off their power plants to avoid the zero to negative power prices.
This causes the power prices to become volatile, since the investments for the power plants that run during the night need to be covered during the night only.
Eventually though the higher price volatility will encourage investments into either demand side adjustability or energy storage systems. This will play out in energy only markets.
The other alternative is to implement a capacity market, which will divide the cost of the baseline production across different production hours by paying producers more for guaranteed production capacity.
"Well you see there is generations and generations of ghouls that have made their entire livelihood off the established and continued monopolization of vital resources such as water and power and for some reason the rest of us haven't gotten together and solved that clear and obvious threat to everyone and everything collectively, I know I don't get it either."
This feels like it is begging for further context.
A system of disturbing goods and services that can't handle negative value is not a system that should be maintained. Our collect pursuit as a species should be the abundance of these things, not the artificially managed scarcity of them.
Capitalism has always been the problem, nothing new here.
Great comments in here that understand the actual issues, instead of, ya' know, the usual.
Something I haven't seen in the thread: Can someone address the costs of keeping the infrastructure maintained? Free power sounds great, but it can never be free. Entire industries must be paid to manufacture pylons, wire, transformers, substations, all that. Then there are the well paid employees who are our boots on the ground. (Heroes to me!)
How is solar disrupting the infra costs?
If anyone is curious as to why we don't run the world off solar, from what I understand the big issue is power grid frequency. Unlike a turbine, solar has no intertia. If you take away light the power drop is instant. With turbines, they keep spinning due to their weight. This is especially important since if a large load is suddenly energized, the turbine might slow down but still won't stop immediately. Maybe in the future giant electric powered flywheels or pumpgen systems can take up the slack. Nuclear would likely also help since those are essentially giant steam turbine generators. Good video with some more info here.
Those flywheels are already being installed right now

I would post that passage from Grapes of Wrath about oranges. But copy-paste doesn't work on my phone
I got you.
The works of the roots of the vines, of the trees, must be destroyed to keep up the price, and this is the saddest, bitterest thing of all. Carloads of oranges dumped on the ground. The people came for miles to take the fruit, but this could not be. How would they buy oranges at twenty cents a dozen if they could drive out and pick them up? And men with hoses squirt kerosene on the oranges, and they are angry at the crime, angry at the people who have come to take the fruit. A million people hungry, needing the fruit- and kerosene sprayed over the golden mountains. And the smell of rot fills the country. Burn coffee for fuel in the ships. Burn corn to keep warm, it makes a hot fire. Dump potatoes in the rivers and place guards along the banks to keep the hungry people from fishing them out. Slaughter the pigs and bury them, and let the putrescence drip down into the earth.
There is a crime here that goes beyond denunciation. There is a sorrow here that weeping cannot symbolize. There is a failure here that topples all our success. The fertile earth, the straight tree rows, the sturdy trunks, and the ripe fruit. And children dying of pellagra must die because a profit cannot be taken from an orange. And coroners must fill in the certificate- died of malnutrition- because the food must rot, must be forced to rot. The people come with nets to fish for potatoes in the river, and the guards hold them back; they come in rattling cars to get the dumped oranges, but the kerosene is sprayed. And they stand still and watch the potatoes float by, listen to the screaming pigs being killed in a ditch and covered with quick-lime, watch the mountains of oranges slop down to a putrefying ooze; and in the eyes of the people there is the failure; and in the eyes of the hungry there is a growing wrath. In the souls of the people the grapes of wrath are filling and growing heavy, growing heavy for the vintage.
