Storage Cost and Performance Characterization Report

For batteries, total $/kWh project cost is determined by the sum of capital cost, PCS, BOP, and C&C where values measured in $/kW are converted to $/kWh by multiplying by four (given the assumed E/P ratio of four) prior to summation. Total $/kW project cost is determined by dividing the total $/kWh cost by four following the same assumption.
