Cycling Capacity is the battery energy storage capacity in kWh available for daily cycling.

Compliance Cycling Capacity is the cycling capacity in kWh of the BESS that is commissioned during the installation of the system as specified on the Certificate of Compliance. Once commissioned, the ratio between compliance cycling capacity and usable capacity shall be maintained for the life of the BESS.

Field-Assembled BESS is a BESS with a combination of battery energy storage modules and inverter components that are installed to operate as a system in the field, and the combination has more than one model number.

Integrated BESS is a BESS that contains both battery energy storage and inverter components and has a single model number.

Reserve Level is the battery energy storage capacity in kWh in excess of the compliance cycling capacity that is available for other functions, and is not subject to the control requirements in section JA12.3.3.1(e).

Usable Capacity is the battery energy storage capacity in kWh that a manufacturer allows to be used for charging and discharging.
