Performance, in this context, can be defined as how well a BESS supplies a specific service. The various applications for energy storage systems (ESSs) on the grid are discussed in Chapter 23: Applications and Grid Services. A useful analogy of technical performance is miles per gallon (mpg) in internal combustion engine vehicles.
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
