ESS Tech, Inc., a U.S.-based manufacturer specializing in long-duration energy storage solutions using iron flow technology, has been striving to secure significant financing for several months to avert a potential shutdown. However, as of May 27, 2025, the company has not succeeded in raising the necessary capital or generating sufficient business. Consequently, ESS Tech has issued notices under the federal Worker Adjustment and Retraining Notification Act (WARN Act) to affected employees and local and state officials, indicating that the company may have to shut down its Wilsonville site by May 30, 2025, if financing is not secured imminently. Despite this setback, ESS Tech remains committed to exploring all options to obtain the needed financing and continue operations. The company emphasizes the importance of its scalable, American-made technology in addressing growing electricity demand and grid resilience. In recent efforts, the company has been awarded a significant project with a major U.S. utility and is in discussions for additional projects, as it seeks to reposition itself for future success.
