Independent energy storage, also known as shared energy storage, is a new type of energy storage facility that is connected to the power grid and serves the power system on a large scale. It is like a "huge power bank" that supplies power to the entire area. By participating in grid services such as peak shaving, frequency regulation, peak load reduction, and absorption of new energy grid connection, it enhances the safety and stability of the power system and earns profits. It is a crucial link in supporting the construction of the new power system.

Stabilizers and energy storage pools that can be built for fluctuating power sources such as wind power and photovoltaics. It can effectively smooth the output of power plants, reduce wind and solar power curtailment, and store surplus electricity for release when needed, thereby improving the quality of electricity and ensuring the stability of the power grid. It is a key technology to support the integration of high proportion new energy into the power grid.

It can install energy storage systems for thermal power plants, forming a 'combined power generation'. Energy storage, with its fast and accurate response capability, assists thermal power units in jointly responding to the frequency regulation instructions of the power grid, greatly improving the regulation performance and efficiency of the units, becoming a flexible and reliable "elite force" of the power grid, and obtaining frequency regulation benefits from it.
