The breakdown of power and energy is derived from Feldman et al. (2021) as described in the methods section. These components are combined to give a total system cost, where the system cost (in $/kWh) is the power component divided by the duration plus the energy component. Figure 5.

What is a battery energy storage system?

A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

How do you calculate battery efficiency?

Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
