Which nuclear does very little to cover. It can't scale up if there's a lull. What you want is gas with carbon capture
My suggestion is that, in practice, storage and efficiency (for example; maybe actually listen to what insulate Britain have to say) though less manly and sexy than more generation, would be practically more helpful...
I remember when pumped water storage was being built in Scotland, it was trumpeted as if it was an important big thing, but the actual generation figures are so small that they are insignificant, except for balancing short term peaks and troughs.

The Severn Barrier was the only scheme that would produce significant power output. Gov reckons 5%, some others say higher. The gov reckons it would cost ~£34b for a predicted 13.5MW
The report is still around
The report is still aroundReally?? I think it's just a case of the fact that the numbers don't stack up and the £34b would be a hell of a lot higher now,
Balancing peaks and troughs (needed to manage nuclear power and coal fired systems) isn't trivial. It saves a lot of money done right.
But if you want more, how about this?

Another 3-4GW of generating power and some of them are designed for over 24 hours duration so they can be used for inter day management.
More allowing gas fired turbines to be run up. We have one finished, working and used. Dinorwig. Surplus power is used to pump water up. Running that off can help with peaks. The advantage is the speed in which they can be set to generate and for that matter top up the reservoir.

So we need more wind turbines and dams. When we don't need the power but have the wind we can pump water back into the resevoir and when we do need the power and we dont have the wind we can open the resevoir.
The resevoir acts as a battery or buffer to manage peaks and troughs in demand and production.

You write that like it's been recently finished.
I visited it while at school.
In the 80's.
It's not very efficient. Losses pumping the water up and from then using it to generate. They also need a suitable site.
Many countries are using lithium batteries to achieve the same thing. Tesla often figures in that area. Dinorwig is good at handling what is sometimes referred to as electric kettle peaks - things that don't last very long and also if needed give time to allow other sources to be bought on line. There is plenty about it on the wiki and it seems others may be built

Wind - simple view - depends on how long periods of high pressure over the country figure in our weather map. LOL That map makes me wonder if all turbines should be on the west side of the country. Beasts from the east are relatively rare.
Can't see why you think that from pointing out it's finished and used. It is.
It's 75% efficient which is pretty good.
Lithium ion is 90%. Compressed air might be between 50 and 70%, but hydrogen would be around 40-50%.
Interesting one as there are signs that the world is going to need rather a lot of it - at some point. That largely down to the power needed to create it. Once you have enough of it it's relatively easy to use. The problem is the green power needed to produce it in a green fashion.
