Is this because of solar? And everyone going out to lunch? Lol So if storage solutions get better, that could flatten out more? Storing for later instead of fire sale.
At midday? Yes it’s solar.
Uhm…that is not possible, unless you are recieving your own taxes.
weird. my -15€ power usage I just used says otherwise
Negative prices happen all the time, prices in ACER (Europes power market) are calculated on a 15 minute cycle (used to be 1hour) and your provider will be charging you negative prices if the electricity price is so low it overcomes the network fees. I’ve seen this exact thing happen on my own power bill.
They are fixed (in total ca. 20 ct/kWh) so they are simply added to the negative price making it less negative.
Here in Canada I pay a flat rate of 9.97 cents per kWh, not sure how that compares to your currency…
Edit: 1 CAD is 1.22097 DEM
Where I live in SoCal it’s around 70 cents canadian per kWh.
Lol DEM hasn’t been used in almost 25 years. 1CAD = 0.62EUR
Electricity is quite expensive in Germany. It’s around 30 ct/kWh but 20 ct are taxes and stuff.
I think these are wholesale prices, not residential.
Large consumers, like steel mills and refineries can adjust their consumption to smooth out fluctuations in base load power production.
For producers, it’s often cheaper to give power away for free or pay consumers to take it rather than spin down a whole gas turbine/reactor/coal furnace. It wastes a shitload of energy to cold start one of those again and synch it with the grid.
Ah that makes sense. Our electricity is mainly hydro electric as well so our system is a fair bit different, and also depends on the time of year for heavy commercial use due to us being buried in snow for half the year lol
These are the electricity spot prices in Germany: https://energy-charts.info/charts/price_spot_market/chart.htm?l=en&c=DE
I truly want to find someone I can do at the home scale with electricity, which isn’t buttcoin, to take advantage of overproduction.
It may not be a direct benefit to you, but if you have some spare compute, you could donate the compute to a project with BOINC.
I’m generally looking for more industrial uses, or ones that can generate some revenue while not being crazy overhead. Farm related uses would best, and I have done a deep dive into fertilizer production which could be viable. And where I live, crushed aggregate is often used as a base for new greenhouse or shade house installs.
Basically, I already have a potential agrovoltaics solution that I can do with the shade, which infact requires significant shade, but where it’s cheap enough to build this kind of system, there ain’t a huge amount of grid infrastructure, so it would be better to use the power in place. I was thinking rock crushers/ aggregate production because it’s something that depending on if the project is grid connected or not and depending on what the power company is willing to pay, could create aggregate or sell the power directly.
I really don’t want to support crypto but unfortunately, as a plug and pay solution, it’s a pretty easy and direct one.
Other ideas we’ve tossed around are refrigeration and food preservation, but the problem with those is that they need the power when they need the power, and so it’s not exactly a way to sink excess supply.
It’s tough because the overhead demands of any additional power sink almost always require 24 hours operation. Basically, the cost of a system to do “something” with your extra power is almost always such that you should probably just be running it 24/7.
Still open to more ideas but it will need to be able to pay for itself for me to get people on board.
Look into hydrogen production from water electrolysis, if you’re really producing a significant surplus.
Oh hello! You posted on /r Technology and latelly /r Collapse before it all went to shit! I’m a big fan of you!
Oh, hi. Glad you liked my posts. The latest /c/collapse incarnation on Lemmy (we’ve had to move twice) is on https://lemmy.zip/c/collapse btw.
There is no meaningful way I can do something with hydrogen outside of as a feedstock into another process.
Things I’ve considered that would help me, running a gravel crusher, or if there was some scaled down hauber Bausch machine. I use a significant amount of gravel and I am always in need of fertilizer.
I know on a small garden scale, clover is a very good companion plant because it affixes nitrogen to the soil. It also acts as a ground cover to reduce moisture loss and suppress weeds, and on top of all of that it attracts bees.
Yeah but I can’t turn electricity into clover
You can run an ICE on hydrogen, with some minor modifications. If you have enough space you can store the produced hydrogen at near atmospheric pressure in a gas holder/gasometer: https://en.wikipedia.org/wiki/Gas_holder
As to nitrogen fertilizer, there have been recent improvements in air nitrogen fixation by way of an electric arc/plasma: https://duckduckgo.com/?t=ffab&q=nitrogen+fixation+electric+arc&ia=web e.g. https://pubs.rsc.org/en/content/articlehtml/2021/ra/d1ra01357b
Yeah I’ve seen the plasma arc thing. I’m vaguely associated with some in the agrovoltaics research community and have considered reaching out. It’s not available to retail consumers yet
What app is it? It was 140€ last night…
Tibber. It’s Cent/kWh.
Here you can find some data, but it seems different (the data, not only the representation) from OP’s
Yeah the prices are not the same between the apps. No idea why.
They includes taxes etc
Ah of course. Electricity Maps is without tax.
Looks like a good time to have a battery!
If they’re paying you to take the power, does anyone have resistors to convert all the 200 or 400KW the power company is willing to give you into heat? 400kw40 cents1hour=160 euro/day.
EDIT: after reading the rest of the comments OP added that these prices include their 20 cents/kwh fee.
One thing to note, these spot prices are the price before any fees, your network fees and all that are per kWh and usually more than the negative sum the electricity price goes to. (probably in this case though -38 cents is a lot)
Negative prices usually only truly exist for enterprise customers that pay 1/5 of the consumer network fees.
Basically 40 space hearers
Do your part to help global warming!
Well, it doesn’t stay at that rate for a full 24 hours. You’d have to just do it whenever the price is negative.
Correct, I calculated if it was just 1 hour per day.
