In the past few decades, electricity production depended on fossil fuels due to their reliability and efficiency [1].Fossil fuels have many effects on the environment and directly affect the economy as their prices increase continuously due to their consumption which is assumed to double in 2050 and three times by 2100 [6].Fig. 1 shows the current global …
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 ].
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. For battery energy storage, the initial cost mainly depends on different materials.
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.
Compared with that of electrochemical power stations, although the initial investment of pumped storage power stations is relatively large, the longer operating life lowers the cost of pumped storage stations that are evenly allocated to each year and obtains higher IRR.
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.
Pumped storage, as the most mature energy storage type with the largest installed capacity, has always received a great deal of attention. At the same time, the high-efficiency battery power station also has a broad application prospect for a reduced cost. Figure 1. Geographical locations of the two selected power stations.
