6 FAQs about [Energy storage power station electricity price mechanism]
How do energy storage stations make money?
In the energy market, energy storage stations gain profits through peak-valley arbitrage. That is, the energy storage system stores electricity during low electricity price periods and discharges it during high electricity price periods.
What is the initial cost of an energy storage power station?
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 ].
How much does energy storage cost?
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.
How much does a pumped storage power station cost?
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.
Do energy storage power stations have a risk of loss?
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.
Are pumped storage power stations better than electrochemical 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.
