I think you are quite likely right but there seems to be a global league 
table for building ever bigger ones much like with camera megapixels...

In the UK there is a secondary problem that most of the power generation 
occurs in the north where it is windy and historically all the dirty 
coal fired power stations were, but most of the consumption is in London 
and the South East. Land prices are however much cheaper in the north.

Guess where they build the battery storage even though the provision of 
North South interconnectors is already borderline for peak load and 
there are known bottlenecks in addition.

Agreed.
