In general, the initial cost of an energy storage power station mainly includes the investment cost of the energy storage unit, power conversion unit, and other investment costs such as labor and service costs for initial installation. The specific calculations of these three parts used the formulas in Appendix 2 of literature [ 29 ].
Moreover, the economic benefits under different subsidy policies are studied, and the results show that energy storage can recover the cost with appropriate subsidy policies (the subsidy of 0.071 USD/kWh for pumped storage power stations is sufficient while the subsidy of 0.142 USD/kWh is required for electrochemical power stations).
Energy storage has the potential to play a crucial role in the future of the power sector. However, significant research and development efforts are needed to improve storage technologies, reduce costs, and increase efficiency.
However, no matter how the energy storage power station participates in the electricity market, the IRR of both power stations does not exceed 10%. This means that there is always a risk of loss in the investment of energy storage power stations.
The influence of energy storage on investment is contingent upon various factors such as the cost of storage technologies, the availability of government incentives, the design of market mechanisms, the share of generation sources, the infrastructure, economic conditions, and the existence of different flexibility options.
For different types of energy storage, the initial investment varies greatly. At present, the investment cost of a pumped storage power station is about 878–937 million USD/GW, which is far higher than that of a battery storage power station, and is closely related to location.
