Eos’s New Deal With CAPAC Energy
Eos, which makes zinc-based long-duration energy storage systems, signed a binding Master Supply Agreement with CAPAC Energy, making the German developer its exclusive distribution partner across Germany, Austria and Switzerland through 2031. The deal includes an initial commitment of 750 MWh with a pathway to scale to 2 GWh of Indensity systems.
CAPAC is already advancing construction of the first Eos projects in Germany, with commercial operations targeted for late 2026. Purchase orders under the agreement will be added to 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. “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.”
The partnership also creates an opportunity for Eos to evaluate local manufacturing capabilities in the European Union, the company said.
