35GWh! Vietnam's Bac Giang Province Prepares Energy Storage Battery Super Factory, CATL Launches Southeast Asia Project!

Global energy storage technology provider Fluence and Vietnam's ACE Engineering Company recently announced a collaboration to build a fully automated battery energy storage system production facility with an annual capacity of 35 GWh in Bac Giang Province, Vietnam.

The factory will produce multiple grid-scale energy storage products under Fluence, including Gridstack Pro and Smartstack, covering behind-the-meter generation and commercial and industrial application scenarios to meet the growing global demand for battery energy storage systems.

Gridstack Pro, as Fluence's flagship product, has obtained several international safety certifications, including UL9540, and is suitable for large-scale energy storage deployments in areas with limited transmission capacity. Smartstack, on the other hand, focuses on a compact structure and integrated energy management functions, catering to commercial and industrial users. Once the factory is built, the expected annual production capacity can support the deployment of approximately 8.75 GWh of 4-hour energy storage systems.

Fluence President Julian Nebreda stated that the new factory will enhance delivery capacity and market responsiveness through automated production and strict quality control.

Although Fluence has temporarily dropped out of the global top five system integrators this year, its undelivered orders still exceed 35.1 billion yuan, with projects mainly distributed in the Americas, while it continues to expand into the Australasia and Southeast Asia markets.

In recent years, several international energy storage companies have increased their manufacturing investments in Southeast Asia. In addition to Fluence, China's Contemporary Amperex Technology Co. Ltd. (CATL) is set to launch a $6 billion integrated battery project in Indonesia in July 2025, covering the entire chain from mining to cell manufacturing. Additionally, Sunwoda announced the construction of an energy storage cell super factory in Indonesia with an annual capacity of 8 GWh earlier this year.

This trend aligns with the Indonesian government's plan to promote a rural energy project with 100GW of solar power and 320GWh of energy storage, highlighting Southeast Asia's increasingly important position in the global energy storage industry chain.
