The Baotang energy storage station, the largest facility of its kind in the Guangdong-Hongkong-Macao Greater Bay Area, is set to propel China's power storage industry forward with its sustainable electricity supply and dominant use of lithium battery energy storage.

The Baotang energy storage station in Foshan City, south China's Guangdong Province, was officially put into operation on Wednesday.

Covering an expansive area of about 3.8 hectares, equivalent to the size of 5.5 soccer fields, the station boasts an installed capacity of 300 megawatts, accounting for one-fifth of the total new energy storage capacity in the Greater Bay Area.

During off-peak electricity hours, the station is recharged by using renewable energy sources such as wind power and solar power. It then supplies the stored green energy to households during peak hours.

"The station can provide the Greater Bay Area with 430 million kilowatt-hours of clean energy annually, meeting the electricity demands of 200,000 households, while reducing carbon dioxide emissions by 300,000 tons," said Lin Qihua, an engineer at the China Southern Power Grid Energy Storage.

The Baotang energy storage station, also China's first lithium battery energy storage station, can integrate multiple technical routes. Lithium battery energy storage constitutes over 90 percent of the country's new forms of energy storage.

"It's challenging to evaluate the performance of different technical routes if they are not operating under similar conditions. However, the Baotang station, a lithium battery energy storage station that integrates multiple technical routes, enables the nine most representative technical routes in China to be compared all at one station," Lin said.

To ensure the safety of power storage stations, temperature control for batteries is crucial, and the Baotang station employs various techniques to address this concern.

"What we have in front of us is an immersive cooling liquid technology. The batteries are fully immersed in the cooling liquid. This system we are seeing employs forced air cooling. These are the outer units of the air conditioners," Lin said.

The control room at the station serves collecting data and assessing the performance of the nine technical routes. A comprehensive analysis is conducted by using a total of 20 indicators. The technical staff anticipates that these results will contribute to the advancement of China's power storage industry.
