Eos Energy Storage (Eos), developer of the low-cost Znyth battery technology, announced a partnership with Siemens to integrate, install, and service energy storage solutions. Eos packages its patented Znyth technology in a modular, pre-integrated, outdoor-rated enclosure called the Energy Stack.
By combining Eos’ DC battery system with Siemens’ storage integration capabilities, the companies hope to set a new standard in energy storage cost and reliability.
“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,” said Eos CEO Michael Oster.
The Eos Aurora 1000│4000, a 1-MW|4-MWh DC battery system, is being sold at $160 per usable kWh for the full DC system with performance guarantees that support up to 20 years of continuous operation with minimal maintenance.
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.
