Either way you are giving way to much credit to the power of the UK military industrial complex.

Taking the limit of free solar power, what would the storage requirements look like for the UK?
But it's not a simple picture. The grid needs to be expanded to distribute power from renewables more efficiently, batteries aren't the only storage option, and the concept is still too centralised.
A combination of distributed rooftop solar with domestic batteries, maybe local storage in substations, strategic national storage, and a mix of sources would be a more effective strategy than trying to park huge batteries around the country in the hope they'll be big enough.
The UK still has a post-war mindset around energy which doesn't make sense in the 21st century.
How many GWh? Citation please.
It’s either 27 or 27GW they are installing sorry.
There’s a massive difference.
Surely it’s per hour though?
27GW per hour is a rate of acceleration of energy use.
