Powering Forward: The Successful Connection of Datang Group’s 50 MW/100 MWh Sodium-Ion Energy Storage System

The first phase of Datang Group’s 100 MW/200 MWh sodium-ion energy storage project in Qianjiang, Hubei Province, has been successfully connected to the grid. This was announced by China’s state-owned power generation enterprise Datang Group on June 30. The project, which has a capacity of 50 MW/100 MWh, is now the world’s largest operating sodium-ion battery energy storage system.

The project is part of the Datang Hubei Sodium Ion New Energy Storage Power Station, which consists of 42 battery energy storage containers and 21 sets of boost converters. It utilizes large-capacity sodium-ion batteries from HiNa Battery Technology and is equipped with a 110 kV transformer station.

Previously, China Southern Power Grid’s Fulin 10 MWh BESS project in Nanning, southwestern China, was the largest operational sodium-ion system. This project, which is the first phase of a 100 MWh project, also uses HiNa Battery’s cells.

Datang Group highlighted the challenges overcome by the project team to bring the Qianjiang project to completion. The successful connection of this phase marks a significant milestone in the advancement of sodium-ion energy storage technology.
