I hate mixing W with Wh.
Is it 211 MWh battery storage with maximum power output (peak, average, etc.) of 211 MW?

It very much looks like it is 211MW lasting for 1h giving 211MWh.

It literally says in first paragraph “…in Sweden to deploy 211 MW / 211 MWh…”

= 1 h
It’s not a strictly technical megazine. That’s why I have doubts.

There is usually a 1:1 between MW:MWh at these capacities, to the point where the 1:2 presented on the article was the first time I’ve heard of another set up in Sweden.

Sadly no info whatsoever on batteries.

I found this on it; still need to read through it. Some sort of lithium battery technology, it seems.

I don’t know specifics on this battery farm, but almost all are essentially fleets of shipping containers filled with smaller batteries, rather than some super-cool-mega-battery, so it’s probably a safe assumption that this is a landmark project in scale, rather than in technology specifics.

Li-Ion seems to be the go-to solution. I hope new static energy storage projects will prefer other options (Na-Ion, flow batteries, …) since there’s a limited supply of Lithium and we need it for vehicles.

This looks exactly like I always imagined battery storage should look like, at least in a first step. Mid-sized batteries strategically distributed in the grid for frequency regulation/grid balancing.
