There was the largest one in Scotland a few months ago.

These are, dare I say it, the easy wins. Reusing the infrastructure from a demolished coal fired power station.

However I have yet to see Battery storage feature in the charts for UK energy usage yet.

I’m guessing that there are a lot of similar such sets that are being, or could be repurposed for battery storage.

We had an interesting case here in the Netherlands, where at the moment the biggest problem for big battery operations is to get sufficient grid transmission capacity. One clever company bought the site of a bankrupt aluminium smelter for cents on the euro, purely because said smelter had a direct high capacity connection to the national high voltage grid. Getting the rest of the site and the machinery was just a bonus.

		Yes, Aldel. I think that will pave the way for more moves like that. They have yet to install anything but the financing is there: https://giga-storage.com/giga-storage-rondt-financiering-van...

There are also four pumped-storage hydroelectric power stations providing a further 2.8 GW of installed electrical generating capacity, and contributing up to 4,075 GWh of peak demand electricity annually.

On one of the sources of grid usage it has a placeholder for batteries but says:

> Several battery storage systems are in operation in Great Britain, but full reporting is not yet available: reports include discharging but not charging. As this would lead to double counting, with power being reported both when originally generated and when discharged from battery storage systems, battery storage data is not yet shown on this site.

		Conceptually it is no different from pumped hydro storage. - for that they simply use negative numbers for pumping and positive for release. I guess it's some technical problem with standardisation/tracking/reporting of the charging right now. As/if Vehicle-to-Grid becomes more widespread, where you have highly distributed battery storage, it will be interesting to see if this will be publicly tracked. Already domestic solar production is largely invisible ( as that mostly manifests in reduced demand ). However I assume, in terms of managing the grid day to day, that such information is going to be important. ( eg if it's a largely cloudly day then that will be manifest as a rise in domestic demand ).

Probably this one: https://www.zenobe.com/news-and-events/blackhillock-battery-...

Very much aimed at storing surplus from a couple of wind farms in the Moray Firth.

Presumably we'll see a lot more of these given the scale of some of the new windfarms...

		That one claims to Europe's biggest, this one is claiming to be the UKs biggest which I guess means an even larger one went live in Europe somewhere in between.

Grid connected batteries are more about aiding grid stability, filling short term mismatches between loads and renewable generators, rather than raw capacity in terms of kWh.

It will be a long time before you will. That's just not the best application right now.
