The Baotang energy storage station in Foshan, South China's Guangdong Province, the largest of its kind in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), is now in operation.
It is the largest grid-side individual energy storage station built in one continuous construction period.
Covering an area of 58 mu (3.87 hectares), an equivalent to five and a half standard football pitches, the power station has a total installed capacity of 300 megawatts/600 megawatt-hours, occupying one-fifth of the total installed capacity of new-type energy storage in the GBA.
It is estimated that the station can export 1.2 million kilowatt-hours of green power per day.
An energy storage station plays a key role in building new-type power systems and supporting realization of China's "dual carbon" goals of peaking carbon dioxide before 2030 and reaching carbon neutrality before 2060.
Construction of the Baotang energy storage station started in late 2022. It was designed to regulate the grid while promoting development of energy storage industry technology.
With advantages like fast responding, flexible deployment and a short construction period, the new-type energy storage station can accurately match the grid to different load requirements and help connect unstable clean energy to the power grid.

Operated by China Southern Power Grid (CSG), it integrates multiple lithium battery-based energy storage technology routes for the first time in China, which is expected to be a strong force for improving the country's new-type energy storage technology.
According to CSG, heat management, structure linkage and battery performance of the lithium battery are the focuses at the station. Nine technology routes have been formed, which means collecting technologies of nine medium-sized energy storage stations into one.
