future cash flows. Determining the appropriate discount rate and term of energy storage is the key to properly valuing future cash flows. #1 Mistake in NPV calculations. A battery of 1kWh will deliver less than 1kWh throughout its lifetime. In many cases, cycling this battery daily for 10 years will not create 1 kWh * 365 days * 10 years = 3
In general, the levelised cost of storage shows the intrinsic value of a kWh of energy delivered by an ESS, for which it should be sold to achieve a zero net present value (NPV). The LCOS is determined as the sum of all investments over the lifetime of an ESS divided by the cumulative energy generated as a result of these investments.

In order to evaluate the economic performance of an energy storage system; many indicators could be utilized such as the levelized cost of electricity (LCOE). It indicates the price of energy which covers the cost of an ESS over its lifetime . The levelized cost of storage (LCOS) is also used to assess the economic feasibility of ESSs .
The study by Schmidt et al. projected the future prices of several energy storage technologies based on the experience curves . The capital costs for stationary systems and battery packs are $340 ± 60/kWh and $175 ± 25/kWh, respectively, regardless of storage technology in the years 2015–2040 .
At the design stage, the amount of electricity delivered over its lifetime can be calculated based on the service life of the storage unit, determined by the number of complete charge-discharge cycles, or based on the estimated lifetime of the ESS considering its operation mode, for example, operating as a backup power supply. 3.
