Anyway, why do you think only having Nuclear power is relevant to
the
problem last night.

Absdolutely if we had been all nuclear that would not have happened.

The nukes are running more or less flat out when they are online. And
how fast can they raise load if not? When one comes back after
refueling or statutary outage they seem to take a day or two to get
up to full chat.


You havce totally missed the point
The nukes are steam turbines. The rotational inertia will cover the grid
for a minute or twow whileÂ* Dinorwig spools up.


Unless an electrical fault stops the power reaching the grid.
Unless it occurs at a time when the mountain reservoir has already
been used up.

The windmills didn't suddenly stop turning, an electrical 'situation'
took that farm off line.

And it's August, so most if not all the coal generators are off for
cleaning and maintenance.

It was the lack of renewable generators to respond in the same way that
thermal plant can, to a sudden loss of generating power.

I wonder what the affect of Hornsea dropping off line when it's fully
built and running at its plated capacity of 6 GW... That's four times
the amount of capacity lost from the grid in this and the
Langannet/Sizewell incidents.

With luck it will neverget built...
