Eos Energy Enterprises, Inc., EOSE
Eos Signs Long-Term DACH Supply Agreement
Eos Energy Enterprises signed a Master Supply Agreement with CAPAC Energy. The deal covers Germany, Austria, and Switzerland through 2031. It also gives CAPAC exclusive distribution rights across the DACH region.
The agreement includes a 750 MWh capacity commitment. However, the framework can expand to as much as 2 GWh. The deal also marks Eos’ first international commercial framework for Indensity systems.
Eos will add purchase orders to its reported backlog once CAPAC issues them. Therefore, the agreement creates a clear route for future revenue recognition. It also strengthens Eos’ commercial position outside the United States.
Germany Storage Demand Supports Expansion
Germany continues to expand renewable power while reducing coal generation. As a result, the country needs more long-duration storage. Eos targets that demand with zinc-based battery systems.
The market also benefits from policy changes. Updated building rules support grid-scale batteries, while co-location reforms improve project economics. A capacity market planned for 2027 may also support storage deployment.
CAPAC has already started building its first Eos projects in Germany. Commercial operations remain targeted for late 2026. The new agreement now gives both companies a broader framework for future projects.
Local Manufacturing Could Strengthen Growth
The partnership also allows both companies to review local production options. European manufacturing could improve supply security and reduce delivery risks. It could also support regional industrial jobs.
Eos designs and manufactures zinc-based long-duration energy storage systems. The company focuses on systems that serve grid, industrial, and critical infrastructure needs. Its technology also targets multi-hour storage demand.
The agreement gives Eos a stronger entry point into Europe. It also links the company with a regional developer already moving projects forward. Therefore, the deal adds a practical growth path across a key energy storage market.
