Energy storage cost calculation and comparative analysis
This concept can also be used in energy storage cost calculations. Assuming that the discount rate of energy storage cost is 7%, the annual operation and maintenance cost is generally about 3% of the initial investment cost. It can roughly calculate the cost per unit of electricity of various energy storage technologies.
