Storage power in Great Britain

Storage shifts energy through time rather than generating it - grid-scale batteries respond in seconds, pumped-storage reservoirs hold gigawatt-hours.

In the live mix, battery discharge sits inside 'Other' upstream, so Storage has no slice of its own - the fleet below is real, the missing slice is an upstream accounting quirk.
