On March 31, the second phase of the 100 MW/200 MWh energy storage station, a supporting project of the Ningxia Power''s East NingxiaComposite Photovoltaic Base Project under CHN Energy, was successfully connected to the grid. This marks the completion and operation of the largest grid-forming energy storage station in China.
In addition, by leveraging the scaling benefits of power stations, the investment cost per unit of energy storage can be reduced to a value lower than that of the user''s investment for the distributed energy storage system, thereby reducing the total construction cost of energy storage power stations and shortening the investment payback

Energy storage stations have different benefits in different scenarios. In scenario 1, energy storage stations achieve profits through peak shaving and frequency modulation, auxiliary services, and delayed device upgrades . In scenario 2, energy storage power station profitability through peak-to-valley price differential arbitrage.
Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
In this case, the energy storage side connects the source and load ends, which needs to fully meet the demand for output storage on the power side and provide enough electricity to the load side, so a large enough energy storage capacity configuration is a must.
The large-scale development of energy storage technologies will address China’s flexibility challenge in the power grid, enabling the high penetration of renewable sources. This article intends to fill the existing research gap in energy storage technologies through the lens of policy and finance.
The power grid side connects the source and load ends to play the role of power transmission and distribution; The energy storage side obtains benefits by providing services such as peak cutting and valley filling, frequency, and amplitude modulation, etc.
The development of energy storage will offer an opportunity to accelerate the energy transition away from coal by providing greater flexibility and reliability to the power grid, thereby enabling high penetration of renewable sources.
