Depending on the considered scenarios and assumptions, the levelized cost of storage of GES varies between 7.5 €ct/kWh and 15 €ct/kWh, while it is between 3.8 €ct/kWh and 7.3 €ct/kWh for gravity energy storage with wire hoisting system (GESH). The LCOS of GES and GESH were then compared to other energy storage systems.
