Large scale battery energy storage system (BESS) supplier Fluence has announced its first shipment of “lithium-ion battery storage systems using US-made batteries, modules, thermal management systems, controls, and enclosures.”
The Virginia-based German-US joint venture (JV) has been attempting to reshore parts of its supply chain for the US market and in May announced a new manufacturing site in Goodyear, Arizona, to produce steel battery enclosures and battery management systems.
That development came eight months after Fluence – a JV owned by German multinational Siemens and US utility AES Corp. – announced the start of production of battery modules at its site in Utah which would include cells produced in Tennessee.
Yesterday’s announcement by the company did not mention battery cell origin but quoted John Zahurancik, president for the Americas at Fluence, who said: “When the Fluence team first put lithium-ion batteries on the US grid, these systems mainly used US-made batteries, enclosures, and inverters but the supply chain shifted overseas as the industry scaled. Storage is a critical piece of a cost-effective electricity system and with this announcement, we’re showing that the US can again be a leader in battery storage manufacturing.”
In fact, slower-than-expected ramp up of Fluence’s US production sites – as reported in the company’s Q3 update – prompted the business to jointly develop a 35 GWh-annual-production-capacity base for its large-scale BESS in Bac Giang province, Vietnam, alongside South Korean partner ACE Engineering. That announcement, in August, reported an 8.2 GW project backlog at the company.
Fluence’s third-quarter report stated the company was confident any reduction in annual revenue caused by delays at its US facilities would be recouped in the next fiscal year – which begins next month – hence the publicity surrounding the business’ first “domestic-content shipments.”
Yesterday’s press release stated Fluence had more than 22 GWh of deployed or contracted energy storage capacity across more than 90 projects in the United States.
pv magazine Australia, reporting Fluence’s plans to recruit an additional 100 engineers and energy specialists at its Melbourne base in the country, in June stated Fluence was operating in 48 markets, with 38 GW of projects deployed, contracted, or under management.
When Fluence announced the start of manufacturing in Utah, in September, the company’s president for the Europe, Middle East, and Africa region, Paul McClusker, mentioned plans to bring manufacturing to Europe but that was before Donald Trump was elected US president and ramped up efforts to bring production to US soil.
