Chinese major lithium-ion battery maker EVE Energy has sealed a framework agreement with US energy storage supplier Fluence, securing a total battery supply capacity of up to 206 GWh for the five-year period from 2027 to 2031, the company announced in a stock exchange filing.
Under the deal, EVE Energy’s subsidiary Hubei EVE Power will deliver a committed 16 GWh of batteries in 2027, with an additional 190 GWh of battery capacity reserved for Fluence for the 2028–2031 period. Built on the two parties’ previous cooperation foundation, the framework covers all battery product types, models and configurations purchased by Fluence from EVE Power and its affiliates, with delivery volumes calculated on a GWh-equivalent basis.
As a framework arrangement, the agreement only sets the overall supply scale. Detailed terms including specific product specifications, exact quantities, pricing, delivery schedules and quality standards will be finalized via subsequent individual purchase orders. EVE Energy also cautioned that potential shifts in industrial policies, market fluctuations and other unforeseen risks may impact the smooth implementation of the cooperation.
A leading Chinese lithium-ion battery manufacturer, EVE Energy maintained robust growth in the first half of 2026, with its energy storage battery shipments reaching 44.46 GWh, a year-on-year increase of 54.9%, while power battery shipments hit 35.76 GWh.
Founded in 2018 by Siemens and US utility giant AES and listed on the Nasdaq, Fluence specializes in grid-scale energy storage systems, supporting services and optimization software. As of June 30, the firm had deployed 19.3 GWh of energy storage systems and held 12.6 GW of contracted storage backlog.
The cooperation faces notable execution risks from both sides. Fluence revealed in August that it had spent around $15 million in upfront costs for a long-term international battery supply deal. On September 16, 2026, it downgraded its fiscal 2026 revenue guidance from approximately $3 billion to $2.4 billion, attributing the adjustment to ongoing production delays and supply chain disruptions at its US contract manufacturing facilities.
The latest deal further deepens the long-term cooperation model between Chinese battery enterprises and US energy storage integrators. EVE Energy has previously reached multiple battery supply pacts with US players including Powin and American Battery Solutions (AESI), with a 19.5 GWh framework agreement with AESI still in progress. Additionally, fellow Chinese battery firm REPT Battero is set to supply 3 GWh of energy storage systems to US-based Energy Vault in 2026 under a 2025 September deal.
