Recently, the Guangdong Huadian Shanwei Overseas Chinese Management District new-type electrochemical ESS power station, co-built with the participation of Nanzi Weimeide, successfully completed a 168-hour trial operation, marking the official commissioning of this 200 MW/400 MWh large-capacity standalone electrochemical ESS power station and making it the first benchmark project in Huadian’s Guangdong region for large-capacity hybrid energy storage combining semi-solid-state and sodium-ion battery technologies. The project innovatively adopts a technical route featuring a high-voltage cascaded large-capacity semi-solid-state ESS combined with sodium-ion battery hybrid energy storage, with high technical complexity, stringent construction standards, and significant implementation difficulty, and is a new-type energy storage pilot and demonstration project of the National Energy Administration.
