Energy storage company Fluence Energy said it partnered with a contract manufacturer to open a new manufacturing facility in Utah to serve regional delivery and address what it said are ongoing supply chain constraints. 

Products are slated to begin shipping from the facility in September to support the company’s Gridstack, Sunstack, and Edgestack storage products. Production capacity will start at 75 Cubes per week with plans to ramp up to 150 per week. The company said the additional capacity is intended to expand its production beyond Asia.

Fluence is jointly owned by Siemens and AES Co. It said it recently created two spare parts hubs in Ireland and Utah to support ongoing operations and maintenance of customer storage assets through a new service called Fluence Spares Direct.

In addition, the company said it plans to open a new product testing lab in Pennsylvania. The lab is intended to serve as the primary location for system-level testing of various configurations of the company’s energy storage products. 

Fluence said it currently has offices in nine countries across the Americas, EMEA, and APAC regions. It also announced the opening of a new technology center in India, becoming Fluence’s first technology center based in Asia. The Fluence India Technology Centre is intended to complement existing technology facilities in North America and Europe. 

Fluence’s first battery-based energy storage project in India was deployed in 2019 at a Tata Power substation in Delhi. The 10 MW/10 MWh project was developed by AES and Mitsubishi and is one of the largest energy storage systems in South Asia.
