The Wall Street Journal is owned by Rupert Murdoch, and the fossil 
carbon extraction business places enough advertising there that Rupert 
spreads their climate change denial propaganda for them.

The problem with the Spanish mainland grid was that they didn't have any 
grid-scale storage, no batteries and no pumped storage. This isn't what 
created the blackout - the network had 3.3 GW of generating capacity 
turn off in 30 seconds, which was clearly a control failure.

It hasn't stopped the fossil carbon extraction industry claiming that 
the renewable source generators were the problem, rather than the grid 
synchronising hardware.

The first grid scale battery ever deployed was the Hornsdale Power 
Reserve in South Australia, installed in November 2017 to solve exactly 
this grid stability problem. It worked a treat, and still does.

Gullible suckers like John Larkin parrot the propaganda.
