Eos Energy Enterprises (NASDAQ: EOSE) has signed a binding Master Supply Agreement with CAPAC Energy, a German battery storage developer formerly known as Nala Energy GmbH, establishing an exclusive partnership covering Germany, Austria, and Switzerland.

The agreement sets a 750 MWh capacity commitment for Eos' Indensity™ zinc-based storage systems, with a pathway to scale up to 2 GWh through 2031. The deal designates CAPAC Energy as Eos' exclusive distribution partner in the DACH region and represents Eos' first international commercial framework agreement for the Indensity™ product.

Construction on the first projects under a previously executed purchase order is already underway, with commercial operations targeted for late 2026. Future deployments will be executed on a project-by-project basis through call-off orders under the master agreement. Purchase orders issued under the agreement will be included in Eos' reported backlog.

"This partnership represents more than a supply agreement, it establishes Eos' entry into a critical international market with a customer already moving projects into construction," said Nathan Kroeker, Chief Commercial Officer of Eos.

Benjamin Henecka, CEO and founder of CAPAC Energy, said the agreement "establishes the framework to scale Eos technology across one of Europe's most important storage markets."

The agreement also includes an evaluation of potential local manufacturing and assembly capabilities within the European Union.
