* Energy storage capacity or the maximum amount of stored energy, in megawatt hours (MWh).
* Storage duration or the amount of time stored energy can discharge at the rated power capacity before depleting the system's energy capacity, in hours.
* Expected system life, in years, based on anticipated operating conditions.
* Estimated energy storage in the first 12 months of system operation, including, Alternating Current (AC) energy (in MWh) for system charging and AC energy (in MWh) discharging from the system to the grid.
* Estimated annual system degradation rate, as a percentage, based on annual reduction in the system's energy capacity.
