View moreIn 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 ].
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.
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.
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.
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.
