That's close to my guesstimates of about $0.10/kwr. So I tend to believe it.

The important thing is battery storage is competitive with peaking plants over a period of hours. And lowest cost when it comes to short term supplies on the order of seconds to an hour.

Also the logistics of containerized batteries is great. You need a place to put them and a grid connection. And nothing more than that.
