For Gravity Storage systems, the levelized cost of storage decreases as the system size increases. Based on the system cost, GES with an energy storage capacity of 1 GWh, 5 GWh, and 10 GWh has an LCOS of 202 US$/MWh, 111 US$/MWh, 92 US$/MWh, respectively. This can be explained by the fact that the system CAPEX decreases with an increased capacity.
The results reveal that GES has resulted in good performance metrics including IRR and NPV of project and Equity, as well as ADSCR, and LLCR. In addition, for a 1 GW power capacity and 125 MWh energy capacity system, gravity energy storage has an attractive LCOS of 202 $/MWh.
