Under the partnership, Holtec has acquired a significant equity stake in Eos. The partnership will support commercialization of the Gen2 Eos Aurora DC battery system and help to establish an automated manufacturing facility in the United States.

Together, Eos and Holtec will deliver and support cost-competitive energy storage solutions that enable dispatchable solar or wind, increase utilization of grid infrastructure, and improve resiliency for commercial/industrial and utility customers.

Holtec, a global supplier of turnkey equipment and services to the nuclear power industry, will establish a subsidiary called HI-POWER to build and operate manufacturing capacity in the U.S., with plans to grow internationally.

Holtec president and CEO Kris Singh said “HI-POWER hopes to build its first plant in Camden, NJ to fulfill a rapidly growing global demand for energy storage using Eos’s innovative technology.”

Eos’ first-of-its-kind manufacturing process entails rapid deployment of highly automated, localized production lines which can be easily replicated in markets across the world. Each line is capable of producing up to 400MWh/yr of the Gen2 Eos Aurora product with improved product quality, cost and reliability. Key product features include:

Pre-integrated, single-drop enclosure that reduces on installation time, field work, and onsite cabling requirements

Expanded scope including newly-integrated thermal management, DC disconnect and auxiliary power capabilities for outdoor-rated, plug-and-play deployment

Enhanced serviceability with added DC control cabinet, allowing for more streamlined module replacement and more competitive long-term warranties

Eos business development and marketing senior vice president Philippe Bouchard said: “We are thrilled to preview our Gen2 solution and distributed manufacturing capability at Solar Power International given that our product is optimally suited for solar + storage applications.”
