Fluence Energy Inc, a US-based global energy storage and digital applications company, has entered into a major battery supply framework agreement with Chinese lithium-ion battery manufacturer Eve Energy, covering 206 GWh of battery capacity between 2027 and 2031. The agreement is among the largest battery supply arrangements announced for the energy storage industry.
Under the agreement, Eve Energy will provide 16 GWh of battery capacity to Fluence in 2027. A much larger 190 GWh allocation is planned for the four-year period from 2028 through 2031. The details were disclosed by Eve Energy in a filing with the Shenzhen Stock Exchange on September 18, 2026.
The financial impact of the agreement has not yet been determined. Eve Energy said it could not provide an estimate of the additional revenue or profit expected from the deal. However, the announcement immediately drew investor attention, with the company's share price rising by around 6–7%.
The framework agreement is not completely fixed. Eve Energy noted that changes in industry policies, market conditions or other factors could affect the cooperation and its implementation.
The announcement also comes at an important time for Fluence. The energy storage system integrator recently lowered its FY2026 revenue guidance by $600 million and increased its expected EBITDA loss to nearly $200 million. The company linked the weaker outlook mainly to delays in ramping up its US manufacturing operations.
Fluence has been building a domestic supply chain in the US to meet growing demand for BESS while addressing tariffs on Chinese battery imports and Foreign Entity of Concern requirements. These rules have increased the importance of non-Chinese supply chains for projects seeking access to US clean energy incentives.
Fluence has not publicly provided details on how the Eve Energy agreement will be used. Given its focus on a US-compliant supply chain, battery volumes could potentially support projects outside the US, although the companies have not confirmed the intended markets.
Fluence continues to develop projects across international markets. In Germany, it recently began construction on two battery storage projects with a combined capacity of 1.1 GW/4.4 GWh for energy company LEAG.
Eve Energy, meanwhile, remains largely focused on manufacturing in China. Although the company entered the energy storage market more recently than some established players, it has expanded rapidly and has emerged among the leading battery cell suppliers for BESS applications, according to Benchmark Mineral Intelligence.
