This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.
Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.
Renewables dipped below $0 for us in California too this year. Fortunately for the utilities, those savings don't get passed along to customers and I still paid $0.53 kW/h. /s
Lucky you.
I still paid $0.53 kW/h.
That is surprisingly expensive, it's more than here (Cambodia), which is notoriously high for the region at around 20c.
Why /s there?
Also fuck PG&E. Fuck that company. Assholes.
Why does it feel like every Nordic country is much better then Sweden these days.
We each have our problems but I have to admit that I haven't heard many positive news coming from there recently.
The energy prices in Sweden were also mostly negative yesterday, and today as well. Although probably not quite as much as in Finland.
Eeh? The price dipped to -70 öre in southern sweden today.. And you should probably not use negative prices as a messurement of success anyways. :)
Because we have been riding high on believing that our infrastructure is the best in the world.

Resistive load. Gotta dump excess energy somewhere.
My electric company here in the us mines bitcoin with it and charges us a "peak time incentive" pricing model.
Sometimes I wonder what it would have been like to be born somewhere like Finland.
Colder and darker for sure
This is not a good thing. Any time generation has to pay to produce, solar and wind rollouts are slowed.
We need better demand shaping methods, to increase load on grids during periods of excess production, and decrease loads during shortages. We need to stabilize rates at profitable points to maintain growth of green energy projects.
We also need long-term grid storage methods, to reduce seasonal variation. A given solar project will produce more than twice as much power during a long summer day as it will during a short winter day. If we build enough solar to meet our needs during October and March, we will have shortages in November, January, February, and surpluses from April through September. We will need some sort of thermal production capability anyway; hydrogen electrolysis or Fischer-Tropsch synfuel production can soak up that surplus generation capacity and produce green, carbon-free or carbon-neutral, storable fuels for thermal generation and/or the transportation sector.
Negative pricing IS a demand shaping method, you need to have a certain % of the electricity produced that is consumed at the same time, otherwise you risk having an unstable electricity grid.
Or just export it - there must be nearby counties that don't have such a good renewable electric situation.
"just export it" sounds so simple, but the required infrastructure is actually incredibly expensive. Also most of Europe is already pretty tightly connected and trade does happen to a significant degree, but I have no idea what the actual percentage is or if it's used to balance oversupply and/or shortages. Kinda hard to find reliable sources for that.
Or water batteries for dams if your neighbors don't need your surplus, this way you don't need to extract lithium to produce regular batteries to store the surplus

When I was growing up, my parents house had thermal storage electrical heating. Generally the heat was only “on” at night when electricity was cheap, then we’d control the temperature during the day with circulation fans. I remember it working really well while saving a ton of money.
Where is the thermal storage heating now? I specifically could use a mini-split heat pump, where the head unit is thermal storage, but I don’t see any such thing online
Meanwhile in the USA the electric companies will mine BTC, and charge consumers more wherever they can. They will even sue people for going solar for "losing out on profits".
Luckily my energy company found a way around all of this to always charge more! We have "Basic Customer Charge", "Summary of Rider Adjustments", "Renewable Energy Rider", and then Sales Tax on all of it. My base charge is over 100$ before they start calculating your actually energy usage. Yay electrical monopolies!
It might be cheap now, but I'm fearing the December - February i.e. the coldest part of the year when the price can get salty. Especially when/if the OL3 (or any other) plant trips offline, the price will bump up a lot.
The good part of having excess eletricity is that doing a "electric-kettle" district heating becomes feasible. So instead of reducing the (windmill) production, it makes sense to dump the excess generation capacity into district-heating. (which has large capacity to store the heat)
This will hopefully lead to storage methods, maybe exportable ones like hydrogen
Hydrogen is not good for energy storage. Round trip efficiency is abysmal and its incredibly difficult to store in the first place
