Counterpoint: electricity markets are terrible for reliability. Markets are great, but there are no pricing signals for reliability. You won't know that your grid will collapse at the first strong breeze, until it happens (see: Texas). Theoretically, it can work because companies might invest in reliable generation, in the hopes of getting $$$$$$$$$ when the spot price goes up through the roof. But in practice, prett…

Actually, electricity markets in Europe work just fine, and provide in fact a lot of required stability. And income events are pretty much instantanious. The only problem European markets have is way too low costs for CO2 certificates which make coal plants way to cheap. Other than that, they work just fine.

Nope. They are not fine. Europe is floundering with its renewable transition.

Right now it's easy to build tons of cheap low-quality wind or solar generation, but it's not economic to build any kind of storage. As a result, Europe is now dependent on natural gas and coal during the winter.

And there's nothing that can change that within the next decade.

It sort of depends on what you mean by markets. In most places in Europe the production of power is on the market, but the actual power grid is not freely traded. The grid is instead handed out to semi-permanent monopolies that are heavily regulated and controlled by governments and/or non-profit NGOs that are essentially a way we do efficient government in the supply sector. It works, but the benefit isn’t usually t…

Having very very few grid failures in Germany is a benefit to consumers, too. Price is only one dimension of consumer benefit.

There are very few grid failures under regulated systems too. Also, was said, the grid itself is a heavily regulated service.

How is it worse in Europe? Where in Europe is it worse? I can't remember the last time the grid failed.

Europe is worse in carbon-free transition.

The grid itself is fine, but it's backed by fossil fuels with no way out.

Strong claims. Any evidence to back them up, besides "Germany shutting nuclear stupid"?

Oh the offices are all on at night. No worries there.

Can’t for the life of me understand that particular Scandinavian peculiarity in what would seem otherwise very rational society. I assume it must have been logical or still is?

To be honest I have no idea. I'm baffled/enraged to walk at night and see rows of tall buildings completely lit up with nobody inside.

It's basically impossible to see anything in the sky other than Jupiter here, because of the insane light pollution.

Exactly. If anything the electricity markets in Europe prove the point they can work.

The grid is a natural monopoly, so it doesn't make sense to let private companies control it and a market wouldn't work.

Electricity production is not a monopoly and can work well as a market, but there needs to be oversight and rules for the trading.

Small modular reactors have almost nothing but disadvantages compared to the good old large-scale PWRs. The ONLY advantage of SMRs is that they are easier to build because only a handful of companies in the _world_ possess technology to build reactor vessels for large-scale PWRs. And none of them are in the US.

Since they’re small they can be placed far closer to urban hubs and other places that suck electricity. The last design plans I saw one could fit within a single city block, buried under ground with only 1 story exposed.

> The last design plans I saw one could fit within a single city block, buried under ground with only 1 story exposed.

This is a completely unrealistic plan, designed to lure investors.

An SMR meltdown will produce enough radioactive contamination to make a small city unlivable, at least for a while. So you'll need a full containment building. You'll need emergency generators, coolant pumps, etc.

Then you have a question of security, an easily accessible reactor will provide a great target for terrorism. So you'll need a perimeter around it with armed guards.

Then there's a question of control. A working reactor requires at least two trained nuclear engineers on duty at all times. So each reactor will likely need around 15 highly specialized engineers. That will have to live within a commuting distance.

Sounds bad already. But that's not all. There's also a question of inspections, something like the NRC can be reasonably expected to regulate several hundred reactors. They are not prepared to inspect many thousands of reactors. And the last thing I personally want is a "self-regulating" nuclear industry.

Any _realistic_ SMR power plant will look just like a regular large nuclear plant, except that it'll have multiple reactor units instead of just one large reactor.

We have yet to see, as they've yet to truly enter the market. So far, the record's not been good for large plants -- they tend to go way over budget and schedule. Case in point: Vogtle.

Rosatom is exporting nuclear power plants within budget and (mostly) on time.

It's simply a question of expertise and experience. The US and Europe have ignored nuclear power for so long, that most expertise was lost long ago. And each new nuclear power plant becomes a unique snowflake.

Aren't you saying the same thing? If externalities were priced appropriately, then storage probably would be a good investment.

PJM does have pricing for reliability. The first California deregulated electricity market had an auction every half hour and all pricing was spot. This caused blackouts and the bankruptcy of Pacific Gas and Electric, even though it was what PG&E had lobbied for. Today, most markets (at least PJM and CAISO) have a "day ahead" auction, and a current auction to fine-tune. Most of the market is in the day-ahead auction.…

Day ahead isn't enough. Need capacity markets & year ahead futures from what I remember last time I read up.

California providers are required to purchase "Resource Adequacy" contracts. Those that are badly managed try to dodge the expense, rather like operating a business without insurance:
