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.

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.

[–] Natanox@discuss.tchncs.de 1 points 21 minutes ago

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.

[–] loopedcandle@lemmynsfw.com 20 points 10 hours ago (1 children)

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."

[–] Aeri@lemmy.world 3 points 8 hours ago

All I know about nuclear reactors is that prompt critical is the "Get out of there stalker" one.

[–] jsomae@lemmy.ml 9 points 10 hours ago (1 children)

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.

I feel like having a colossal battery pack could help with that problem.

[–] iii@mander.xyz 3 points 1 hour ago

Colossal is an understatement

[–] ProgrammingSocks@pawb.social 6 points 11 hours ago

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.

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.

[–] easily3667@lemmus.org 3 points 7 hours ago (2 children)

People keep reposting this like it's a gotcha.

It's not

If prices are negative most of the day there is less incentive to provide the capacity that's needed during the night. The money for capex has to come from somewhere so it goes up significantly at night. And of course the negative price isn't "real", it just means power plants will shut down for swaths of the year until it's affordable to keep the remainder running. Which then means lower average capacity on days that are cloudy, or additional maintenance on systems that only run in the winter. So then people throw battery stuff around... batteries are expensive. Really, really, really, really expensive. So you have to find a way to keep capacity up that's not absurdly expensive or hard to maintain, or you have to keep all your fossil fuel plants at the ready while producing $0 in income to offset the upkeep, which...yes, gets passed to the consumer.

I know people want to simplify the national grid which spans across all continental states and connects to literal billions of devices producing and consuming power...but it's actually kinda complicated.

[–] merdaverse@lemmy.world 2 points 1 hour ago* (last edited 38 minutes ago) (1 children)

The original article literally frames it as an economic problem under capitalism. Most of the article is about value deflation, not about the niche case of storing excess energy until it is profitable to sell again.

Lower prices may sound great for consumers. But it presents troubling implications for the world’s hopes of rapidly expanding solar capacity and meeting climate goals. It could become difficult to convince developers and investors to continue building ever more solar plants if they stand to make less money or even lose it https://www.technologyreview.com/2021/07/14/1028461/solar-value-deflation-california-climate-change/

Maybe take a break from the capitalist apologia to understand that this shouldn't be a problem for a society that is trying to move away from cooking the planet.

[–] barsoap@lemm.ee 2 points 35 minutes ago* (last edited 33 minutes ago)

"Instead of trying to solve the problem we currently have, with the systems and tools that are there, how about we forget about the problem and work on something much much harder instead".

Don't get me wrong you're absolutely free and welcome to advocate for systemic solutions. But don't attack people working on alleviating symptoms in a practical way or I'll call you an accelerationist. "Here's how we implement socialism! Step one: Burn the planet".

[–] Turret3857@infosec.pub 10 points 7 hours ago* (last edited 7 hours ago)

wow, its almost like the government that we pay taxes to should be what's powering the country and not private corporations that are only concerned about profits 😋

[–] Rooskie91@discuss.online 216 points 17 hours ago (3 children)

If you're describing nearly free and unlimited electricity as a problem, you may want to reconsider some things.

[–] MartianSands@sh.itjust.works 145 points 17 hours ago (44 children)

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.

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?

[–] merdaverse@lemmy.world 2 points 1 hour ago* (last edited 1 hour ago)

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.

[–] iii@mander.xyz 1 points 1 hour ago* (last edited 1 hour ago)

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.

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.

"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."
