The UK is aiming for around 27GW of battery storage by 2030.
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.
