The Baotang energy storage station, the largest facility of its kind in the Guangdong-Hong Kong-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. 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 hours, the station is recharged with renewable energy sources such as wind and solar power.
