2. Exactly this. If the intel services don't trust the ad industry, why should the rest of us in the general public?

5. I cannot fault this choice, much as I fault the government of mainland China/Zhong Guo for many other things.

6. Good to know...

7. This has to be remedied.

9. ...sigh...

40 years too late...

My first girlfriend was Mormon. Somehow I don't think she'd have gone for that one though.

My prediction is that the Anglesey nuke takes an additional 10 years of discussion before it's given the go ahead and then is delayed by another 5 years by court action and protests and some sort of inquiry in to the pricing / costing with construction when started over running by 5 years.

Then someone will stick a solar panel on top of it.

I doubt it will get cancelled.

Good question.

To which the answer is - I'm not sure. (Looking at the articles I've linked to I'd guess $70 per kilowatthour of storage capacity removes any situation where nukes have an operational-cost advantage i.e. there are no situations where a nuke is helpful on any grid, at any time, in any set of requirements, but I'd want to think a bit about that.)

I'm also not sure it's entirely the right question as I think the key number is the overall cost per MWH for the whole system.

I think it would be dependent on the scenario and the situation you find yourself in and therefore what job the nuclear plant is doing on your grid.

If you have a lot of solar, not much wind, electricity demand is driven by day-time cooling and the job the nukes are doing is providing electricity overnight then the cost of storage doesn't have to come down as much because you will be cycling the storage every day - storage capital costs amortised over many cycles.

If you have lots of wind but not great solar and electricity demand is driven by winter heating then the job the nuke is doing might be covering for a couple of week period when you have low winds and avoiding having to add storage that you only use a couple of times a year.

This guys seems to think the answer is $20 per kilowatt hour of storage capacity makes 100% renewables cheaper than all other current alternatives with a 100% Effective Availability Factor over a twenty year period (i.e. no black-outs or brown-outs ever) $150 if you are prepared to tolerate a few interruptions from time to time or will allow some other form of demand management to play e.g. over-sized interconnectors or demand management or some nukes.

By 2026 the developers of the nuclear site would need to be confident that the cost of storage wasn't going to fall much further over the next couple of decades.

Or that they would have some state guarantees of prices.

I think you are right about the need for state guaranteed pricing.

I guess what I'm fishing about it in is this - if your cost of production is about $125 / MWH starting in say 2030 (based on Hinckley C) and, for the sake of argument, let's assume that the UK's wind and solar fleet are priced at an average cost of $125 / MWH (made up of much cheaper direct power with some expensive storage) and the cost of that is coming down by say 1% a year on average then in about 20-25 years time, in 2045, when the 2030 vintage of solar PV / wind turbines and batteries gets renewed you about $25 / MWH or 25% too expensive. And the situation is getting worse.

That's a big state guarantee to ask for and you have to be pretty confident that the state will actually back that guarantee.

And you have another 40-60 years of design life left to run from 2045 and I don't see any mechanism whereby energy prices start to go back up. Not that I think renewables prices will keep falling at their current rate for 60 years, but I'm certain about the next 10 and confident about the next 20.

I think it's a different ask if your price was $125 and long-term energy prices looked like they might be in a band of $115 to $140 with the occasional excitement of an oil war.

I think that probably it either gets canned straight away or it will rumble on for decades. I think once these things have gone through a few gate reviews they've got a life of their own - including the fact that many large and influential organisations have invested in the lobbying efforts required to keep multi-generational project alive politically.

So I think one of the following happens

1) it goes no further in 2022
2) the current government goes ahead with the scheme and by 2026 it is obvious it is going to be a boondoggle but by then everyone is too committed, there is some messing about with reviews for 10 years and the government gives a price guarantee it can and will default on and the developer pretends to believe this and passes on the additional financiing costs to the consumer and the project goes bust in about 2050 and gets nationalised and everyone knows it but nobody says that bit outloud.

Western governments are not in the habit of renegging on credit or guarantees of support but see RBS in 2008-10 for example or the dancing around who was guaranteeing the deposits in Irish and Icelandic banks.
