Big hunks of rotating metal are slide bolt simple and reliable.

And South Australia stopped replying on them for grid frequency stabilisation as soon their first grid battery - the first in the world - came on line.

Big hunks of rotating metal are just stored energy - so are charged up batteries, and fast inverters let you correct the grid waveform faster, and more accurately.

I hadn't realised that the French government have deliberately limited
400kV link capacity over the Pyrenees to protect EDF nuclear power from
cheaper competition from Spain's massive solar PV investment.

 The US has its examples as well.
 The need for spinning reserve in both directions may change their
calculus.

There no need for any spinning reserve. Grid scale batteries can do that   job faster and cheaper.
