2.4 gwhr is a monster of a battery.

For reference the UK has about 7gw output of battery (assuming all on at the same time. I don;t have the capacity though.) The UK is one of the more mature grid battery places in europe.

The UK has some mammooth projects in the pipeline as part of the Long Duration Energy Storage Cap-and-Floor scheme [1].

There's a 200MW/3,600MWh project which has planning permission and also a 400MW/7,200MWh proposal [2].
