Since releasing my oil video I've had so many people claiming that renewables will never work and we need nuclear power instead.

What's odd is that almost all of the messages mention that nuclear power is the only solution for the "base load".

I have a degree in Electrical Engineering and I took several nuclear science electives. I like nuclear energy. But I received so much "base load" gaslighting that I started to doubt my own understanding of the situation.

Energy consumption goes up and down throughout the day, but the "base load" is the minimum amount, even at the lowest point in the day. So nuclear power is good for providing this "base" because it's consistent and always running.

The issue is that renewables sometimes output so much electricity that, especially when it's sunny, the grid makes *way* too much electricity. The electricity consumption of the grid minus renewables is called the "residual load", and it very very often goes NEGATIVE.

This means that the concept of "base load" is not really relevant, because there is no consistent base. And when the residual load goes negative, the wholesale price of electricity goes negative as well.

Last year the Netherlands had negative wholesale electricity prices for about 7% of the year, and that amount is only going to grow.

You can't afford to run a nuclear reactor when electricity prices are negative, but you also can't shut it down every day either.

This was always my understanding of how renewables make the concept of "base load" irrelevant, again, as a person with a literal degree in Electrical Engineering.

But I was gaslit by so many people that I felt the need to research the current situation again today.

This could just be people using out of date information, but I suspect this is anti-renewables propaganda. Otherwise I don't know why so many people would even know what a "base load" is.

When I did some reading on the current situation, I found a lot of sites out of Australia that were repeating this "base load" idea, in the context of nuclear power.

I suspect that this is fossil-fuel propaganda.

Fossil fuel companies love promoting nuclear power because they know it takes decades to get a reactor built (if it gets built at all), and in the meantime, everyone keeps using fossil fuels.

It's the perfect way to cripple renewables without being obvious about it.

@notjustbikes the only honest reason for using nuclear power is the desire to have nuclear weapons.

@mohs @notjustbikes

"The neglected factor is the military dependence on civil nuclear industries. Maintaining a nuclear armed navy or weapons programme requires constant access to generic reactor technologies, skilled workers and special materials. Without a civilian nuclear industry, military nuclear capabilities are significantly more challenging and costly to sustain. "

The hidden military pressures behind the new push for small nuclear reactors

If billions are being invested to power submarines not homes, the public deserves to know.

The Conversation
@notjustbikes oh hey, that was actually my missing link as to why fossil fuel companies promote nuclear! 
@CIMB4 @notjustbikes they know that nuclear is such a tarpit that it would take decades to get any power out of it, and in the meantime they can carry on selling fossil fuels.
@CIMB4 @notjustbikes
This reasoning (waiting for nuclear keeps us using fossil fuels) is nicely explained in the Australian context in this video by @thejuicemedia https://youtu.be/JBqVVBUdW84

@notjustbikes

I'm in Australia, living in a house with PV panels and a battery. I sell electricity to the grid in the mornings and evenings and buy during the day, if needed. Here are the prices per kWh sellers may get tomorrow morning, the percentage at the bottom is the share of renewables in the grid and actual prices from today afternoon.

...any more inflexible supply from the coal power plants (or nuclear if we had it) and they go negative.

@notjustbikes I think the term you’re after is “dispatchable power”, which means production that can rapidly be ramped up or down - eg. Renewables firmed with batteries, or some types of fast response gas turbine. “Base load” is a vestige of the old coal power stations, which need to output approximately constant power, so we had to find ways of flattening consumption, eg by incentivising night time consumption.
@wall0159
However, the assumption that nuclear power is dispatchable is a myth: once you payed all the sunk cost to build a nuclear plant, it has to run 24/7 for a very long life if it ever wants to have remotely competitive prices per output.
@notjustbikes
@Sweetshark

Interestingly, French nuclear power plants modulate their output power all the time and still have electricity much cheaper than Germany 🤔
@kravietz
Lol "für Privathaushalte"
@Sweetshark

You literally buried me under an avalanche of very concrete arguments and data, much appreciated 😆
@kravietz
Also: Is this generation cost (I doubt it)? If those are the end consumer prices, one has to keep mind, that french prices are heavily subsidized.
@Sweetshark

@nibbs @Sweetshark

Electricity tariffs in Europe are very complex, all of them are somehow subsidised, and in addition to that they are part of the single market, which further distorts the prices of every single source at any given time.

The primary problem is however not that they are or aren’t subsidised in Europe, but that they are most certainly subsidised in China, which is both the cause and effect of EU buying most industrial production from there.

Leave me out of this -- we discussed thus before, when @kravietz ignored industrial electricity price is below 20 ct/KWh in Germany and unsubsidized nuclear production cost is higher than that.
@nibbs

@Sweetshark

But these industrial prices are subsidised, aren’t they?

@nibbs

@wall0159

If you check current Germany generation you will see it constantly runs 8-15 GW on biomass and lignite (brown coal). This is literally the textbook example of baseload generation, in a country that has absolutely insane amount of installed power in renewables

@notjustbikes The main centre-right political party was pushing nuclear power at the last election. So it also has some support as a culture war issue.

Both of the major parties accept large donations from the mining and resource extraction industries, so it is not just a fossil fuel thing.

@notjustbikes

Fossil fuel companies love promoting nuclear power because ...

They also abhor the idea of a decentralized grid, with local production, maybe even in the hands of the people who consume the power, because it threatens the structure of the current grid, with few well known producers and a lot of distributed consumers.

There is a tiny piece of truth in this, as a grid that also accommodates a lot of distributed producers requires a lot more digital control and modernization, and it also requires a somewhat different structure in cabling and power distribution, but on the other hand such a structure will be a lot more flexible and resilient, too.

Financially, some large scale fossil power producers (RWE in Germany, for example) are partially state owned and profits from them are being used to pay for state pensions or finance other parts of repeating state payments. These parts of the state resist ANY kind of change with an almost unsurmountable stubbornness, and these kinds of dependencies are also badly documented.

@notjustbikes Yea, the liberals were trying to push for nuclear SMRs last election, but they lost **hard**, but there was such a massive misinformation push, it just failed because... the liberals are such a mess I suppose.

@notjustbikes This worked flawlessly in the last election in Sweden 4 years ago. The winning coalition bet EVERYTHING on this narrative and it did seem to be part of them winning the election. 4 years later the main outcome of this is almost all renewable projects have been cancelled due to the market uncertainty that was created.

Election coming up in September and they seem to bring back the favorite from last time, let’s see if it works twice. Polls indicate no.

@notjustbikes Solar on suburban homes is a funny thing. At the latitude of Amsterdam, it can lead to demand evaporation for 7-8 months of the year if the home has a sufficiently sized battery.

The solar from a typical suburban home can carry 10-15 kWp of solar, leading to 7-11 MWh production per year in east/west configuration and 13-16 MWh production in a south facing ideal deployment.

There is a 1:10 production difference between January and June, though, so the household likely needs to buy power Nov-Feb, but will likely break even or almost break even in Mar, and not consume any power from the grid in April to September, and begin to load from the grid lightly on October.

Heating with a heat pump will have them but 3-4 MWh during winter.

(Numbers based on our 75 kWh/(year and qm) home, and our demand, but they seem to be applicable on a more general scale, too).

For power producers this means they have to supply power to homes like ours only for winter.

Fortunately wind + battery can actually do that without CO2.

@isotopp
Nachfrageverpuffung, oder wie heißt das auf deutsch?

#solar #autarkie
@notjustbikes

@isotopp @notjustbikes but batteries are terribly expensive. I have 5 solar panels and I've completely recovered that investment in less than two years because they were subsidised.They would cover half my daily needs if I could use all the production. So I've considered buying batteries, but there's no way I can recover that investment in a reasonable timeframe. At least not with the current electricity cost, which is very low.

@Disputatore @notjustbikes

20 kWh battery cost me 7280 Euro incl installation here. 30 kWh are possible, and cost marginally more.

https://www.zonneplan.nl/thuisbatterij/kosten

I have other costs for a freestanding house in the Greater Amsterdam area, and while the battery costs are not so small that they are immaterial, they are not "terribly expensive" – one and a half very good Kalfhoff e-Bikes, or 1/3 annual cash bonus.

Kosten thuisbatterij: prijzen en informatie

De kosten van een thuisbatterij liggen gemiddeld tussen de €5.000 en €8.000. Check snel wat een thuisaccu voor jou oplevert!

Zonneplan

@isotopp @notjustbikes that's a fabulous price. I have a quote of 3 300 euros for 3kWh of batteries plus installation. I would have to replace my inverter because the one I have is not hybrid:
X1-Hybrid-3.0D- 952€ + IVA

Smart meter- 125€ + IVA

BMS MC0600- 450€ + IVA

3.0kWh High voltage 90V-116V Lithium Battery- 900€ + IVA

Instalation- 255€ + IVA

IVA is the same as VAT.

@isotopp @notjustbikes when I say that the batteries are expensive I'm talking about a cost-benefit point of view. In Portugal, only one third of the power bill results from consumption. The remainder is the power availability and grid access costs. Even if I was to remove consumption for most of the year, I would still have to pay two thirds of the bill for the whole year. So the monthly savings would be fairly small. It could take upwards of 15 years to offset the investment.
@isotopp @notjustbikes Roughly corresponds to what I am seeing in my home, with a recent heat pump and 18 year old solar panels. No battery yet, but if we had, we would also not consume any power from the grid from mid April to early October.
@isotopp @notjustbikes here in the States, white reactionary suburbanites in Texas cover their roofs with solar and sell power back to the utilities there, but in the cities where real people live, we have people who can't afford their electric bills, and their landlords could care less about solar because they don't pay for household electricity. Distributed power needs to work at the neighborhood level and prioritize the needs of the dispossessed.
@notjustbikes there's a lot of nuclear FUD in Australia... and far too many people are swallowing it without question
@notjustbikes isn't one big downside of nuclear energy that the tractors are inert/lazy to react to the load?

@notjustbikes as an Australian, I can assure you that the Australian base load thing is hot garbage designed to keep control of energy in centralised corporate hands.

So yup, perfect for arguing against renewable / distributed energy with an authoritative sound that is actually hollow nothing.

@notjustbikes

Lots of nuclear trolls/shrills.
Not all of them are real people.

Here in Australia, we have lots of mainly uncontrolled rooftop solar.

The sun shines and The commercial solar farms get pushed out.

The constant on "baseload" coal plants lose money with negative prices. They have started to learn to dance. Like the UK coal plants. Ramping their output up and down. But they have their limits. No longer baseload.

@notjustbikes

So we have a solution.

Give away 3 hours of electricity for free in the middle of the day. When we have the most amount of negative prices and spare solar capacity.

Perfect for charging evs. Or shifting loads away form peak.

Also a big boom in home batteries is also seeing demand reduction in evening peaks. Charge own batteries, rather then export, then use your own electricity in peak. Or sell it back to the grid when it is needed.

https://reneweconomy.com.au/the-hours-the-market-wants-back-free-daytime-power-or-a-fix-for-solar-and-wind-curtailment/

The hours the market wants back: Free daytime power, or a fix for solar and wind curtailment?

What does it mean when an offer appears consumer-friendly but is also system-convenient? And what becomes visible when price is placed beside curtailment rather than read in isolation?

Renew Economy
@The_Sun @notjustbikes negative prices for "overproductive" periods should be passed on to consumers, but somehow aren't. Markets are imperfect mechanisms, and they are really bad at correcting what is fundamentally a misallocation of resources.

@celeduc @notjustbikes

//Checks my post to make sure I included the bit about 3 free hours of electricity esch day//

@The_Sun @notjustbikes free is a good *start* but production is curtailed by operators as prices drop below zero. This means equipment that could otherwise be producing energy goes idle *because* it is centralized, and I can't store it in my battery or use it because it isn't available.

@celeduc @notjustbikes

Negative prices and solar excess has seen the big batteries and pumped hydro charge cheaply and discharge at peaks.

There are a number of retail plans in Australia that exposure you to wholesale rates, including negative prices. So you can do the same and make money. Or join a virtual power plant and make money.

You think free electricity won't see people shift their loads to the middle of the day? Which will see more generation supplied from large scale solar.

@celeduc @notjustbikes

Meanwhile free electricity will see people move pool pumps, hot water from overnight controlled loads, designed to give coal something to do in the middle of the night low demand. Further putting the nail into coal.

The extra demand in the middle of the day will be met with large scale solar that was previously heavily curtailed.

@notjustbikes that was literally what the conservative (Liberal & National Party coalition) opposition pulled at the last election here in Australia:

Cancel renewables.
Start up a nuclear program (despite multiple failed attempts).
Throw money at gas and coal.

They didn't win the election

@notjustbikes

It took 4.5 years to build one of the recent nuclear power plants in China and if we buy all our PV & inverters from them they clearly must know what they’re doing, don’t they?

@notjustbikes have not seen the video yet for context

Can't it be a misunderstanding that they mean grid momentum and not baseload and get the two confused?

@IcyPalm @notjustbikes I suspect it’s far more simple than that. Your average person likely has zero knowledge of the grid frequency or why it’s important. They don’t know about the duck curve. Transmission is how the electricity gets from their local power plant to their house.

What they do know:
* Solar turns the daylight into electricity
* We need electricity 24/7
* The sun doesn’t shine 24/7
* Batteries don’t last forever (and what if there’s a cloudy week, if …, if …, etc.)
* Therefore, we need a base load that gets us through the night and cloudy days. (What’s a base load? Idk I heard it)
* Nuclear is relatively clean and the scare factor was semi-artificially created by the fossil fuel industry, therefore it must be really good because they’re really bad

It’s the liberal equivalent of “why don’t we just drill more?”

I don’t think it’s some giant conspiracy.

@ClickyMcTicker @IcyPalm @notjustbikes Honestly, I think all of these are valid concerns.
I think it's curious that people yapping about renewables' success always talk about the Netherlands, or California, or Texas, or Australia. No one wants to renewable-ify somewhere in Siberia where you have little to no sunny days and very little coastal winds.
@arina @ClickyMcTicker @IcyPalm @notjustbikes FWIW solar panels do generate electricity on cloudy days, albeit less than on days with a clear sky. If clouds blocked 100% of sunlight you wouldn’t be able to see anything when it was cloudy out
@greenpepper22 @notjustbikes @IcyPalm @ClickyMcTicker @arina Totally! Today is cloudy yet I've generated enough surplus power from my solar panels to fill up the battery while working at home and doing laundry etc.
@arina @ClickyMcTicker @IcyPalm @notjustbikes Let's put a pin in that and come back to it when Siberia is the last place that hasn't been renewableified. We'll run a transmission line up there. Actually, you know what, we could do that RIGHT NOW.

@Salty @arina @ClickyMcTicker @IcyPalm @notjustbikes Siberia produces so much hydroelectric power that USSR built many energy hungry aluminium plants that import the ore from Brazil. Siberia does not need solar electric power. Just remove misplaced industries.

Even better. Allow people to migrate to a warmer climate. Look up how Siberia is depopulated already. It is not impossible to turn it back to nature reserve.

@alexey88008 @Salty @ClickyMcTicker @IcyPalm @notjustbikes
I honestly don't think I saw anything as dumb as "well people just shouldn't live in colder climates" before. Amazing.
@arina Dumb or not, it is what I feel. I do not want to live in cold climate. Grandparents of my grandparents were forced to move here by the government. And now I do not have much choice. Migration is expensive. Most countries have some kind of anti immigration policy. And my passport is not exactly welcome in countries you would want to live in.
@alexey88008 "I do not want to live there therefore no one should".

@IcyPalm
Could be in some cases, but I've seen the "baseload" argument on German-language social media quite a lot and I'm very sure the fraction that knows about grid-momentum is even smaller than the fraction that knows what baseload actually means.

:)

@notjustbikes

@notjustbikes I'd always understood generator base load to be something like having to keep all your lights in the house on at a low setting, just glowing, so then when you needed proper light, they'd be no delay in coming up to full brightness.
Or is that an incorrect analogy?
@sothach @notjustbikes that's clever because starting old school bulbs is a full chug chug moment drawing all the amperage possible.

@notjustbikes say more! Smart grids and smart devices that can operate at optimal times.

Also, China had this problem with coal stations that couldn't stop despite needs being met. Is that still happening?

@rood @notjustbikes

Talking about "China" without a year number attached to what is being said is really hard, because things change rapidly there.

In 2024, China has been deploying new coal plants at approximately the same rate as they have been decommissioning older, dirtier ones.

The new plants have very low utilization rates, and are built as swing capacity. They are also being paid as reserve, base money for the ability to jump in on demand, and then additional money if they are actually needed.

@isotopp @notjustbikes around 2015 solar peaked, but the curtailment of coal became a whole other political infighting issue. After reading some of the latest reports I see that coal curtailment became impossible and it went the other way for most of the following decade. All this despite renewables trouncing coal quite regularly.

Provinces opting for new coal beyond mere back-up were basically going rogue.
