I saw HIS "jump" as even bigger!  Why have we had SO MANY similarly sized
events in the past -- before ANY renewables were deployed?

     "Damn nukes and coal burners!"

Why were the hydro and nuclear plants IN THE AFFECTED SPANISH REGION so
poor at providing that "inertia" (even if only to allow THAT part of the
country to safely "island"?)  Why were they among the last sources to come
back online?

The failure in the deployment of renewables is the ASSUMPTION that they
can just "bolt onto" a stable grid.  Even as their incorporation into
that grid alters its complexion.

One can argue that spinning masses have to be protected (which is why they
disconnect) whereas a grid sourced completely by renewables (and BESS)
can adapt to whatever the instantaneous characteristics of the network
happen to be.

What's magical about 48Hz?  Why not 47?  53?  Again, LARGE mechanical loads
will be the ones to suffer most but what portion of the system *load* is
thusly vulnerable?
