With a total investment of 650 million yuan ($89.52 million), the project successfully completed its initial charge-discharge unit test on May 4 after more than a year of construction.Is gravity energy storage a good investment?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 $/MWh.
What is gravity energy storage?Gravity energy storage (GES) technology relies on the vertical movement of heavy objects in the gravity field to store or release potential energy which can be easily coupled to electricity conversion. GES can be matched with renewable energy such as photovoltaic and wind power.
How much does gravity storage cost?For Gravity Storage systems, the levelized cost of storage decreases as the system size increases. Based on the system cost, GES with an energy storage capacity of 1 GWh, 5 GWh, and 10 GWh has an LCOS of 202 US$/MWh, 111 US$/MWh, 92 US$/MWh, respectively. This can be explained by the fact that the system CAPEX decreases with an increased capacity.
Is a project investment in energy storage a viable investment?The project investment in all the studied energy storage systems is demonstrated viable to both project sponsors and lenders since the IRRs of the project for all systems in their last year of operation are larger than the projected WACC and the IRR of equity in their maturity year are better than the return on equity. 5. Financial analysis.
Are energy storage systems feasible?From a financial and an economic perspective, the studied energy storage systems are feasible technologies to store large scales energy capacities because they generate sufficient returns for project investors, have a high ability to service debt payments from cash flows, and, most importantly, achieves sufficient financial performance. 1.
