In this article, the investment cost of an energy storage system that can be put into commercial use is composed of the power component investment cost, energy storage media investment cost, EPC cost, and BOP cost. The cost of the investment is calculated by the following equation: (1) CAPEX = C P × Cap + C E × Cap × Dur + C EPC + C BOP
It involves dividing all expenses (including capital expenditures and operation and maintenance costs throughout the system's lifetime N) by the amount of energy discharged by the storage system, Eout, over the same period. The capital cost and energy output are adjusted for the time value of money using the discount rate.
