Grid-side energy storage ndrc
It stores excess electricity—say, from solar farms at noon—and releases it during evening peaks. Unlike rooftop batteries, these systems connect directly to transmission networks, balancing supply and demand at scale. The NDRC calls it a "cornerstone" for China's 2060 carbon neutrality goal.

What are NDRC & Nea's 'guiding opinions' on grid-side energy storage?
Regarding grid-side energy storage, in July 2021, NDRC and the National Energy Administration (NEA) issued the "Guiding Opinions on Accelerating the Development of New Energy Storage", wherein they advocated for the exploration of tariff mechanisms for grid-side independent energy storage capacity (NDRC and NEA, 2021).
What is a grid-side energy storage operator?
Regarding the operating model, the grid-side energy storage operator provides services to the grid, while the grid pays the energy storage plant operator for leasing the energy storage plant, which is the capacity tariff. The grid and energy storage operators often have conflicting interests as independent economic entities.
Does China have a grid-side energy storage system?
In recent years, China has been developing large-scale grid-side energy storage facilities. However, the deployment of grid-side energy storage has primarily depended on government subsidies.
What is the capacity Tariff of grid-side energy storage?
Based on the capacity tariff calculation model of the Stackelberg game proposed in this paper, the capacity tariff of grid-side energy storage is 415.58 CNY/kW.
Who invests in grid-side energy storage projects in China?
In China, grid-side energy storage projects are primarily invested in and operated by the State Grid Integrated Energy Services Group Ltd. or third-party investors (Liu et al., 2023).
How does the grid-side energy storage choose to charge and discharge power?
Charge and discharge power and state of charge of the grid-side energy storage. According to Fig. 7, it can be seen that the grid-side energy storage chooses to charge at the time of low and flat electricity prices and discharge at the time of peak electricity prices.
