Make More in America Initiative to fund expansion of ESS long-duration energy storage manufacturing capacity

Manufacturer of long-duration energy storage systems (LDES) for commercial and utility-scale applications, ESS Tech, Inc., has announced that a financing package of $50 million was approved by the Export-Import Bank of the United States (EXIM) Board of Directors under the Make More in America Initiative.

The financing will fund the expansion of ESS’ production capacity in Wilsonville, Oregon, to meet rapidly growing global demand for LDES. ESS is delivering iron flow energy storage systems to customers in Europe, Australia and Africa, providing energy resilience and accelerating the global transition to clean energy. 

Launched in 2022, EXIM’s Make More in America Initiative (MMIA) makes available medium- and long-term loans, loan guarantees, and insurance to finance export-oriented domestic manufacturing projects.

MMIA supports environmentally beneficial projects, small businesses, and transformational export transactions, in areas including semiconductors, biotech and biomedical products, renewable energy, and energy storage while supporting domestic jobs. The partnership with EXIM is expected to deliver economic benefits both in Wilsonville and nationwide. ESS manufactures 100 percent of its products in the United States, utilising a predominantly domestic supply chain that spans 29 states, which will maximise the economic benefits delivered by this financing package.

“Our partnership with EXIM underscores the critical role that American-made clean energy technology will play in the global clean energy transition” said ESS CEO Eric Dresselhuys. “ESS’s iron flow technology is already deployed in Australia and Europe and with this agreement, we are well positioned to meet the growing needs of our current and future global customers.”

Financing approved by EXIM will enable the tripling of annual production capacity in Wilsonville. New manufacturing capacity funded by this initiative will be based upon the proven battery module production processes developed and refined by ESS.

“We are proud to approve EXIM’s fourth Make More in America transaction to small business and energy storage manufacturer ESS” added Chair Reta Jo Lewis. “This transaction will ensure that EXIM continues to meet our mandates to support technologies that are critical to the global energy transition while bolstering supply chains and supporting hundreds of good- paying jobs at home.”

As a leading commercial manufacturer of iron flow battery technology, ESS’s LDES solutions mitigate renewable intermittency and enable renewable energy to become baseload energy. With up to 12 hours of energy storage capacity, ESS iron flow solutions bolster energy resilience and reliability, ensuring electricity is consistently available, despite aging infrastructure, climate impacts, location, or fluctuations in renewable supply and demand. 

Recently, ESS announced a partnership, financed in part by EXIM, with Sapele Power, a Nigerian integrated energy company, representing one of the first energy storage projects in Nigeria and the entire sub-Saharan Africa region. The deal won EXIM’s Sub-Saharan Africa Deal of the Year Award for driving investment in Africa and creating new opportunities across the continent. ESS also has partnerships with global energy and services companies including Honeywell International, German energy company LEAG and, through a local partner, Australian generator Stanwell Corporation, among others.
