Nah, lets squash capitalism first.
Not saying we shouldn’t do both, but in reality waiting to destroy capitalism before fixing the grid just means you have too much theory and not enough praxis.
It's funny how capitalist apologists in this thread attack the format of a tweet and people not reading the actual article, when they clearly haven't read the original article.
Negative prices are only mentioned in passing, as a very rare phenomenon, while most of it is dedicated to value deflation of energy (mentioned 4 times), aka private sector investors not earning enough profits to justify expanding the grid. Basically a cautionary tale of leaving such a critical component of society up to a privatized market.
This is what the Cabal is doing !!
Ughh, no, negative prices aren't some weird "capitalism" thing. When the grid gets over loaded with too much power it can hurt it. So negative prices means that there is too much power in the system that needs to go somewhere.
There are things you can do like batteries and pump water up a hill then let it be hydroelectric power at night.
Except the grid overload thing isn't even an issue with renewables, since wind can be shut down in a matter of 1-5 minutes (move them out of the wind) and solar literally just be disabled. Any overload they produce would be due to mechanical failure, where you can cut them off the grid since they're in the process of destroying themselves anyway (like in those videos where wind turbines fail spectacularly). Otherwise renewables are perfect to regulate the grid if available.
In a hypothetical grid with an absolute majority of many badly adjustable power sources (like nuclear) you'd have to work with negative prices to entice building large on-demand consumers or battery solutions. So far nobody was stupid enough to build a grid like this though.
tl;dr, this whole problem indeed is about economics and therefore may very well be a "capitalism thing". Renewables do not overload the grid.
But it doesn't say "it can generate too much energy and damage infrastructure", they said "it can drive the price down". The words they chose aren't, like, an accident waiting for someone to explain post-hoc. Like, absolutely we need storage for exactly the reason you say, but they are directly saying the issue is driving the price down, which is only an issue if your not able to imagine a way to create this infrastructure without profit motive.
Yeah mate. The people writing here are economists not engineers, and that's the professional language for what they're talking about in their field. It's like if a nuclear engineer said "oh yeah, the reactor is critical" which means stable.
I hear the point your making and the point OP made, but this is how really well trained PhDs often communicate - using language in their field. It's sort of considered rude to attempt to use language from another specialty.
All of that context is lost in part b.c. this is a screenshot of a tweet in reply to another tweet, posted on Lemmy.
The way it's supposed to work is the economist should say "we don't know what this does to infrastructure you should talk to my good buddy Mrs. Rosie Revere Engineer about what happens."
All I know about nuclear reactors is that prompt critical is the "Get out of there stalker" one.
Economists think in terms of supply and demand. Saying it drives prices down or negative is a perfectly good explanation of a flaw in the system, especially if you're someone on the operating side.
Boy do I hate economists.

I feel like having a colossal battery pack could help with that problem.
Colossal is an understatement
Absolutely. The hydro thing is really just a water battery, it's just stored in potential kinetic energy instead of chemical energy. But sodium cells are starting to look like a good option for chemical energy too.

I see this posted a lot as if this is an issue with capitalism. No, this is what happens when you have to deal with maintaining the power grid using capitalism as a tool.
Power generation needs to match consumption. Always constantly the power grid must be balanced. If you consume more than you can generate, you get a blackout. If you generate more than you use, something catches fire.
Renewables generate power on their own schedule. This is a problem that can be solved with storage. But storage is expensive and takes time to construct.
Negative prices are done to try and balance the load. Its not a problem, its an opportunity. If you want to do something that needs a lot of power, you can make money by consuming energy when more consumption is needed. And if you buy a utility scale battery, you can make money when both charging and discharging it if you schedule it right.
That's not renewables being a problem, that's just what happens when the engineering realities of the power grid come into contact with the economic system that is prevalent for now.
I can't ragebait if you people are being logical 😒
I see this posted a lot as if this is an issue with capitalism. No, this is what happens when you have to deal with maintaining the power grid using capitalism as a tool.
The framing of it as the problem being that the price is going down rather than that excess power is feeding into the grid is what makes it an issue with capitalism. The thing you should be questioning is why MIT Technology Review is talking about some consequence of the problem that only exists because of capitalism instead of talking about the problem itself.
And before you downvote/object with some knee-jerk reaction that I'm being pedantic, consider this alternative way of framing it:
The opportunity is that solar panels create lots of electricity in the middle of sunny days, frequently more than what's currently required, so it is necessary to develop new flexible sources of demand so that the excess energy doesn't damage the power grid.
That's pretty vastly different, isn't it?

Not really. It's like saying toast falls butter side down, vs toast falls non-buttered side up?
Perhaps some are conditioned for an emotional response, rather than a rational one, upon hearing certain words? That's why you suggest to avoid them, even to describe the same issue?

Also, fwiw, you can curtail wind turbines incredibly quickly. They're the quickest moving assets on an electrical grid typically. So you are using them to balance the grid quite often. You can just pitch the blades a bit and they slow or stop. it's not really a tech problem, but a financial one like you said.
I'm not sure much about solar curtailment, other than the fact that they receive curtailment requests and comply quite quickly as well.

Here in the EU, the DC-AC transformers are mandated to shut down if the grid frequency is out of bounds.
Nice comment! Thanks.

Hear me out: a giant water balloon. Roughly the size of the sun.
If you're describing nearly free and unlimited electricity as a problem, you may want to reconsider some things.
It's a very capitalist way of thinking about the problem, but what "negative prices" actually means in this case is that the grid is over-energised. That's a genuine engineering issue which would take considerable effort to deal with without exploding transformers or setting fire to power stations

You can read the Technology Review article here discussing why this is problematic beyond a JPEG-artifacted screenshot of a snappy quip from a furry porn Twitter account that may or may not have read the article beyond the caption. We need solar power plants to reach net zero emissions, but even despite their decreasing costs and subsidies offered for them, developers are increasingly declining to build them because solar is so oversaturated at peak hours that it becomes worthless or less than worthless. The amount of energy pumped into the grid and the amount being used need to match to keep the grid at a stable ~60 Hz (or equivalent where you live, e.g. 50 Hz for the PAL region), so at some point you need to literally pay people money to take the electricity you're producing to keep the grid stable or to somehow dump the energy before it makes its way onto the grid.
One of the major ways this problem is being offset is via storage so that the electricity can be distributed at a profit during off-peak production hours. Even if the government were to nationalize energy production and build their own solar farms (god, please), they would still run up against this same problem where it becomes unviable to keep building farms without the storage to accommodate them. At that point it becomes a problem not of profit but of "how much fossil fuel generation can we reduce per unit of currency spent?" and "are these farms redundant to each other?".
This is framed through a capitalist lens, but in reality, it's a pressing issue for solar production even if capitalism is removed from the picture entirely. At some point, solar production has to be in large part decoupled from solar distribution, or solar distribution becomes far too saturated in the middle of the day making putting resources toward its production nearly unviable.
In other words… Maybe 29 word Twitter captions aren’t a great way to discuss issues?

As a solar punk, I have solar panels, some batteries, and all my stuff runs off USB or 12v. I don't pay utilities
How do you heat water?
He shakes himself really fast in the tub
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.

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?
The actual issue, as stated in the original article is value deflation, aka investors not making enough money to justify energy transition to a timeline where humanity still exists in 100 years. Decoupling the issue from the political and economic aspect is disingenuous at best.
Here in Belgium, the component related to power generation is only about one fifth of the residential power bill.
Most are (1) connection costs (what you describe), (2) taxes, (3) subsidies for solar and wind to replace gas power generation, and (4) since 2 years, subsidies for gas power generation for when there's too little solar and wind.
It’s called a connection fee that is levied whether or not you used any energy that month. Those fees will likely go up to make up for decreased energy distribution revenue.
