Therefore, we define the investment cost in an ESS to be $0.0326/kWh per hour. Similarly, and according to the values reported in [38], we consider that a grid-scale ESS costs $ 380 /kWh and has a lifetime of 15 years. As a result, we define the savings from not investing in an ESS to be $0.00289/kWh per hour.
