Price per kw and price per kwh stored. And price per kwh over the expected lifetime of the battery itself (longevity and reliability and safety and disposal will have to be factored into total cost of ownership).
No, kw (power) is a fundamentally different unit from kwh (energy).
Energy is conserved, so that’s how we use it and pay for it, but power capacity is very important for infrastructure. A battery that can hold 1 GWh worth of energy, but can only output it at a rate of 10 MW, might have a ton of limitations to its usefulness.

Still only price and kw. 😤
