Fluence Locks In Multiyear Battery Supply Deal With China’s EVE Power

Fluence Energy has signed a multiyear master supply agreement with EVE Power, the battery arm of Chinese manufacturer EVE Energy, to secure cell deliveries running from 2027 through 2031, the two companies confirmed this week. Fluence’s own announcement, issued September 24, does not state a volume, but EVE Energy disclosed the framework to the Shenzhen Stock Exchange the week before at approximately 206 GWh, a figure widely reported as one of the largest single battery supply commitments in the storage industry to date.

Locking In Cells Before the Next Demand Wave

Fluence framed the agreement as a way to gain visibility into volume and pricing years in advance, rather than negotiating cell purchases order by order. Roman Loosen, Fluence’s senior vice president and chief supply chain officer, said the EVE Power relationship strengthens the company’s access to advanced battery technology and supports commitments to customers building out grid-scale projects globally. The company said it is pursuing a separate, distinct approach for the US market that includes domestic content options, a distinction that matters given the tariff and local-content rules now shaping where American utilities can buy storage hardware.

The agreement lands as Fluence’s own order book has been swelling. The company reported a record $6.4 billion backlog and a 45.6 GW/163.7 GWh storage pipeline as of June, with quarterly order intake nearly tripling year-on-year, driven in part by a first large data-center storage order. Locking in cell supply years ahead gives Fluence a way to backstop that pipeline against the kind of battery shortages that have periodically slowed grid-storage rollouts elsewhere, and comes as other storage players pursue their own supply strategies, from repurposing used batteries for grid storage to backing alternative chemistries such as sodium-ion cells that could eventually ease reliance on any single lithium-ion supplier.

What 206 GWh Actually Means

At current utility-scale battery pack sizes, 206 GWh is enough cell capacity, in principle, for tens of gigawatt-hours of deployed storage projects annually once the agreement ramps up — comparable to a meaningful share of the roughly 3,200 GWh that BloombergNEF projects the global utility-scale market outside China will add between 2024 and 2035. For scale, a single large hybrid project such as Masdar and EWEC’s round-the-clock clean power plant uses on the order of 19 GWh of storage, underscoring how many projects a 206 GWh cell framework could theoretically supply. Neither company has disclosed the contract’s dollar value, and the figure describes a supply framework rather than a guaranteed, locked-in order; actual deliveries will depend on how much storage capacity Fluence’s customers ultimately contract for over the five-year window.

A China Supply Chain Still Central to Storage

The deal underscores how central Chinese battery manufacturers remain to global energy storage buildouts, even as Western developers diversify their supplier lists and as some markets, including the United States, push incentives toward domestically produced cells. Fluence has pursued parallel efforts on that front, including its own US manufacturing capacity, while continuing to rely on established Chinese suppliers like EVE Power for the volumes needed to serve utility and hyperscaler customers outside the US.
