It is shown that the LCOS decreases up to 28.8% when decreasing the discount rate from 8% to 6%. Whereas a discount rate of 4% results in a decrease of up to 47.5% reduction in the LCOS of the investigated systems. For example, The LCOS for Gravity Storage would fall from 111 US$/MWh to 87 and 66 US$/MWh.
