Nuclear is as capable of rapid dispatch as coal was and coal ran the
entire grid once.

You can store a lot of energy in a big steam boiler

And in the UK we have enough hydro to cover the intermediate dispatch
requirements.




We were discussing high capacity , do keep up.


You really dont understand the subject do you?

Very short term dispatch is catered for by the rotating masses of the
turbines: That covers a powerstation tripping

Minute level dispatch is catered for by hydro and steam in boilers.
hpor level dispatch is catered for by turning the nukes up and down. Or
having some gas.
Renewables contribute zero to all of this and batteries and hydroigen are
an expensive inegffficent (and dangerous) substitute for pumped storage


Pumped storage only lasts for hours, this is not enough to cover extended
periods of excess demand. Hydrogen offers the potential to provide months
of storage.

Hydrogen is expensive but if you have over capacity you might as well do
something with it. We do not have enough mountains to pump water up.


Neither do the french and their system works fine.
