> demand adapts to more variable supply and dynamic pricing

You want demand to adapt? I'm supposed to turn the lights out when the wind's not blowing, or what?

Demand shouldn't adapt, supply should adapt. Connect more and bigger power grids, add energy storage to the grid in large enough quantities.

Your "solution" is like telling people to give up cars. They won't.

Yes, you get the gist of my position (for cars too).

So when it gets really cold and there's little wind, we'll freeze to death? Gotcha.

People who decided to use directly grid electricity for heating but are not willing or able to pay for it during cold spells will find they have a summer house. Consumers can of course have electricity contracts that have fixed monthly prices as a derivative bought from electricity market actors. As the transition doesn't happen overnight, people and the social safety net will have time to cope and adapt.

In cold climates people have increasingly well insulated houses that are relatively affordable to heat, and mostly use non grid electric heating. And can also shift power usage around the day because it takes a day or so for the house to cool uncomfortably.

Well, it's good that you're transparent. People should abandon their homes because of your policy.

Which energy sources that emit less co2/kWh than nuclear power should be used to heat houses in that case?

> (In cold climates people have well insulated houses that are relatively affordable to heat, and mostly use non electricity heating, like thus far)

What are talking about? What kind of non-electricity heating? Let's burn some coal or what?

I'm in Sweden. It gets cold. Houses are well insulated and typically heated via quite efficient electric air-to-air or air-to-water heat pumps. Our electricity has been like 98% co2 neutral since the 70s because of a 50/50 mix of hydro and nuclear as a base load.

Now, ironically, the leftist politicians (including the green party) here are dismantling all of this because they and the journalists don't understand the concept of base power, because they don't understand the difference between power and energy. Their solution is to build lots and lots of wind power plants.

So why would the electricity prices become unaffordable for heat pump heating in your well insulated houses with local hydro and nuclear power?

By non electric heating methods I meant CHP and biomass based heating.

But yes, old energy inefficient houses in cold climates should be replaced. There's no need to get dramatic over it, houses are machines for living and it depends on circumstances how far to extend their lifespan. (Except some historical houses of course)

> So why would the electricity prices become unaffordable for heat pump heating in your well insulated houses with local hydro and nuclear power?

Umm. This whole thread is about the existence of nuclear power. Is it hard to understand that if nuclear power went away, the baseload would become extremely expensive during cold and wind-free days? That's a substantial part of the year, here.

In a nuclear rampdown scenario, hopefully it would not come as an overnight surprise. Usually there are plans on a 10 year timescale or more. But I'm not arguing against nuclear, just for dynamic electricity pricing.

Like some people found out in Texas, with 5 digit bills due to short term spike?

That's the kind of thing we need to design for and handle using contracts containing hedges or cutoffs and price reactive usage. Texas isn't a cold climate place so relying on grid electricity to cover the exceptional weather is probably not the best plan in the post fossil future. But insulation will help with this and hot weather AC electricity usage both.

It's unrealistic. Policy based on everyone living in Neverland doesn't work.

So you believe the grid can be said to be working well with occasional dips to 0MWh? Or is some base load in fact an obvious necessity?

You may argue that the current value of the base load is artificially high, but there obviously is some fundamental base load given by the kinds of consumers you have.

> So you believe the grid can be said to be working well with occasional dips to 0MWh?

With distributed generation and storage, yes, it's plausible to have periods of 0MW grid demand.

> there obviously is some fundamental base load given by the kinds of consumers you have.

The kinds of consumers you have are not a fixed quantity; particularly their on-site use, generation, and storage patterns all vary over time.

I'm talking about 0 MWh for the entire grid, which includes all of the distributed generators. So, by definition, shutting down each and every piece of electric equipment connected to the entire grid. You truly believe that is a tenable position?

If not, than you must accept there exists some necessary base load. That can be provided from base production like it is today, or it could theoretically be provided from storage and over-production in a hypothetical renweables-only grid.

It's unlikely to hit 0 even at night, no reason to stop all the windmills and hydro, and there will be stored energy buyers and sellers. But there won't be production guarantees to some level based on anticipated demand.

I know it's unlikely, but the point was that there exists some minimum need of energy, even in the most flexible grid imaginable, some base load necessary.

Technically yes, I guess the grid has to be kept energized to work.

> Base load is just a made up convention.

Seriously.

Ok, bad wording. How about: It emerges from conventional fixed supply. In any case it's no law of nature. So not a concept that is necessarily relevant in the furure.

Base load results from demand, not from supply. You positively, absolutely must provide a certain amount of power at all times.

> In any case it's no law of nature.

Yes it is. It's a law of human nature :-)

The relationship of supply and demand in the grid is an equation, if they don't match you get blackouts or other funky things. When you have dynamic pricing, variable supply works out, as nobody is obligated to produce any fixed amount of power.

Yeah,base load still exists as in the dictionary definition (floor of aggregate power supply and demand), but it ceases to be a fixed level that is a hard production quota.

> When you have dynamic pricing, variable supply works out, as nobody is obligated to produce any fixed amount of power.

No, thats not really how it works out.

Baseload should actually be called baseload demand. The idea of baseload demand, is that there is some minimum level of electricity, that will always be demanded, almost no matter how high prices go.

Or, in other words, there is some about electricity demand is very inelastic.

So no, you can't just increase electricity costs. Because then electricity costs will massively spike, and cause huge amounts of problems.

You are massively underestimating the amount of problems and costs that it would put in people for demand to be as elastic as you want it to be.

It would be way cheaper and better for everyone, if there was simply enough baseload supply to meet the baseload demand.

I think the situation in Texas recently illustrated this pretty well.

Texas illustrated what happens in the current old system if there are unexpected drops due to breakdowns in supply when consumers are relying on affordable supply following consumption. Pricing can't fix a situation like that.

Big problems maybe at first sight, but there are many ways of overcoming them. When automated price following behaviour is implemented in eg AC and heating and car charging systems, the spikes will be greatly lessened. Also, energy storage actors can sell into spikes, which will work to clip the spikes and encourage investment into energy storage.
