There are successful grid battery installations, but as far as I know, there are no grid-scale battery installations. Existing installations have really small capacity, and are only used for things like demand smoothing. The only energy storage solution deployed at scale is pumped hydro storage. |

"Really small capacity" here apparently means "roughly 4 hours of discharging as fast as possible".
