Eos Energy Storage and Siemens Launch Industry-Leading Battery Storage Solutions

Eos Welcomes Siemens as Aegis Partner to Support Integration of Utility-Scale Energy Storage

NEW YORK, January 24, 2017 - Eos Energy Storage ("Eos") - pioneer of the safe, ultra-low cost Znyth® battery technology - today announced a partnership with Siemens to integrate, install and service energy storage solutions.

"Working with such an established energy industry leader like Siemens is an exciting step for us and the energy storage industry," said Eos CEO Michael Oster. "By combining Eos cost and performance advantage with Siemens capabilities in system integration and project execution, we are able to offer solutions that reduce risk and complexity for the customer while setting a new benchmark for energy storage reliability and cost-effectiveness."

The Eos Aurora® 1000│4000—a 1MW|4MWh DC battery system—is being sold today at $160 per usable kWh for the full DC system with performance guarantees supporting up to 20 years of continuous operation with minimal maintenance. Eos packages its patented Znyth® technology in a modular, pre-integrated, outdoor-rated enclosure called the Energy StackTM.

Leveraging this novel design, Eos and Siemens have jointly productized an energy storage system including AC power conversion and controls that enables modular installation and ease of maintenance, lowering cost throughout the project development cycle. This joint product offers utilities an economic alternative to conventional system upgrades, renewable energy developers a means of dispatchable hybrid power, and commercial customers load management savings paired with enhanced power quality and reliability.

"Our goal is to standardize and productize energy storage projects with focus on reliability and return on investment for the customer," said Siemens VP Brian Dula. "This process starts with modeling and analytics to optimally size the energy storage asset and carries all the way through project implementation and performance guarantees. By offering a solution with supporting services, Siemens will help customers realize the full benefits of the Eos Aurora battery."

Together, Siemens and Eos are able to offer energy storage solutions for a broad range of grid-connected and off-grid markets. Collaborative testing and product validation is setting the stage for MW-scale installations in the first half of 2017—including a California Energy Commission funded project with Pacific Gas & Electric (PG&E), demonstration of a behind-the-meter, commercial and industrial product at the University of California at San Diego, and a first-ever utility microgrid installation combining the Eos Aurora with on-site solar and diesel generation.

Eos is proud to formalize Siemens entry into the Aegis Program for system integration partners. Under Aegis, Eos works with industry-leading providers of power conversion and controls to integrate the Eos Aurora DC System into a standardized, AC product supported by installation, maintenance and warranty services.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
