Siemens, Eos Link Up For Utility-Scale Energy Storage Integration


Eos Energy Storage is partnering with Siemens to integrate, install and service utility-scale energy storage solutions.

Specifically, Siemens has joined Eos’ Aegis program as a system integration partner. Under Aegis, Eos works with 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.

Leveraging Eos’ Aurora battery system and Zynth battery technology, Eos and Siemens will jointly offer an energy storage system that includes AC power conversion and controls that enable lowered costs throughout a project’s development cycle, according to the companies.

The Eos Aurora 1000 | 4000 – a 1 MW/4MWh DC battery system – is sold at $160 per usable kWh for the full DC system. It also includes 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 Stack.

The companies say the offering will give 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,” says Brian Dula, vice president of Siemens. “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 offering energy storage solutions for a broad range of grid-connected and off-grid markets. The two are planning megawatt-scale installations for the first half of this year – including a California Energy Commission-funded project with Pacific Gas & Electric; a demonstration of a behind-the-meter, commercial and industrial product at the University of California at San Diego; and a utility microgrid installation combining the Eos Aurora with on-site solar and diesel generation.
