Recently, big news emerged in the energy storage sector: Fluence and ACE Engineering’s new factory in Bac Giang Province, Vietnam, has officially commenced operations. This is no ordinary factory—it is an automated energy storage facility with an annual production capacity of up to 35 GWh. For the energy storage industry, this move represents both a new milestone in the strategic partnership between the two companies and a significant shift in the global energy storage manufacturing landscape.
Factory Overview
The factory is designed with an annual production capacity of 35 GWh, placing it among the top-tier facilities globally in terms of scale. More importantly, it employs a fully automated production process. Fluence officially refers to it as a “future-oriented factory.” For the energy storage industry, increased automation not only reduces reliance on manual labor but also directly enhances consistency, safety, and product yield.
The factory will produce two of Fluence’s core products: Gridstack Pro™ and Smartstack™. These products are tailored for grid-scale energy storage, emphasizing high reliability and large-scale deployment.
Strategic Significance
Julian Nebreda, CEO of Fluence, stated: “This factory will enable the company to deliver market-needed products faster and at a larger scale.”
Danny You, CEO of ACE, emphasized that the new factory will bring more flexible manufacturing, shorter delivery cycles, and higher quality standards.
Southeast Asia has become a critical region for the transfer and expansion of the new energy industry chain in recent years. Vietnam offers advantages in labor costs, policy support, and better connectivity to markets in Asia, Australia, and the Middle East.
Fluence is a globally leading energy storage system integrator, while ACE is a Southeast Asian manufacturer specializing in system enclosures and integrated solutions. ACE has deep resources in understanding the power policies, land use, and grid access in markets such as Vietnam, Indonesia, and the Philippines. Their collaboration essentially represents a complementary partnership of “technology + market,” enabling the accelerated deployment of large-scale energy storage projects in Vietnam and broader Southeast Asia to capitalize on the opportunities presented by new energy and grid upgrades.
By expanding production, Fluence and ACE are not only meeting current orders but also laying the groundwork for the future energy system. In the coming years, such manufacturing upgrades will become increasingly common. Those who lead in production scale, automation, and global布局 are likely to gain an advantage in the energy storage race.
For Fluence, this move helps reduce manufacturing costs. Meanwhile, in European and American markets, where “Made in China” batteries face potential tariff policies, entering with a “Made in Vietnam” identity can help mitigate some tariffs and improve market acceptance.
