Binding Master Supply Agreement secures a 750 MWh capacity commitment with a pathway to scale up to 2 GWh of Indensity deployments across Germany, Austria and Switzerland through 2031
First projects under a previously executed purchase order now in construction
PITTSBURGH and FRANKFURT AM MAIN, Germany, June 17, 2026 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the "Company"), America's leading innovator in designing, manufacturing and providing zinc-based long-duration energy storage systems sourced and manufactured in the United States, and CAPAC Energy (formerly Nala Energy GmbH), a German developer and operator of battery energy storage systems, today announced a binding Master Supply Agreement establishing an exclusive partnership across Germany, Austria and Switzerland (DACH region).
The agreement expands an existing customer relationship into a long-term commercial framework extending through 2031 and establishes a 750 MWh capacity commitment with potential to scale up to 2 GWh. It also designates CAPAC Energy as Eos' exclusive distribution partner in the DACH region. Importantly, this marks the first international commercial framework agreement for Eos' Indensity positioning the company for continued expansion across key European markets.
Germany is rapidly emerging as a critical market for long-duration energy storage. The ongoing phase-out of coal-fired generation, ambitious renewable energy targets, continued solar capacity growth, and increasing grid complexity are driving demand for flexible, multi-hour storage solutions capable of balancing supply and demand. Recent regulatory developments, including updated building code privileges for grid-scale batteries, co-location reforms, and a capacity market mechanism expected to launch in 2027, are further enhancing the long-term outlook for storage deployment in the German market.
CAPAC Energy is currently advancing construction of its first Eos projects in Germany with commercial operations targeted for late 2026. This new agreement builds on that momentum by establishing a structured framework for future deployments, enabling project-by-project execution through call-off orders under the Master Supply Agreement.
"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. "Germany is an attractive energy storage market in Europe, and we believe Indensity is particularly well positioned to address growing demand from data centers, industrial customers and critical infrastructure where space, flexibility and reliability are increasingly important. This agreement creates a foundation for long-term growth in the region alongside a local partner."
"This agreement establishes the framework to scale Eos technology across one of Europe's most important storage markets," said Benjamin Henecka, CEO and founder of CAPAC Energy. "We have moved quickly from selecting Eos technology to project construction and are now establishing a framework that supports future growth across the DACH region. As power demand grows across industry, infrastructure and data centers, we see a clear need for storage that can deliver flexibility over multiple hours and support a more resilient power system."
The partnership also creates an opportunity to evaluate local manufacturing and assembly capabilities in the European Union. Regional production could strengthen security of supply, support development of European supply chains and contribute to skilled industrial employment in Germany and neighboring markets.
Under the Master Supply Agreement, as purchase orders are issued, they will be included in Eos' reported backlog.
