BYD does batteries at scale now for about $45/kWh.

The cheapest US made ones are $120/kWh.

The yield and the lack of automation is the holdup.

The 400 MWh scale project started operating here in NZ last week. Total project cost $537 USD (900 NZD) per kWh.

Current FIR/SIR cost seems to linger around $0.2 NZD / MWh. No idea how do calculate payback on this.

Because kWh is for energy, not power?

Battery capacity is measured in (k)Wh as it stores energy.

And batteries store energy.
