Eos Aurora DC Battery System under new, lower pricing model

Eos Energy Storage is moving its Eos Aurora DC Battery System to a forward-pricing model. The company is taking orders today for volume purchases at a price of $160 per usable kWh for shipment in 2017 and $95 per usable kWh for shipment in 2022.


Eos says it is the first company to accept orders below $100 per usable kWh for a complete DC battery system, including battery modules, battery management system and outdoor-rated enclosure. Eos’ price-cap guarantee ensures that future purchases will receive the lower of the contracted price or any future price for an equivalent volume purchased the same year. The company is also offering up to 20-year performance guarantees at additional cost to optimize capacity under a wide range of applications and use cases.

“These price points correspond to a levelized cost of energy of approximately $50-60 per MWh for storage, roughly 30 percent lower than the lowest projected cost for any competing storage system,” says Jim Hughes, Eos Chairman of the Board. “With these economics, Eos will become the default solution for new peaking capacity and will enable a dispatchable renewable energy product that outcompetes conventional power generation.”

System details

Built on standardized 250 kW/1 MWh DC building blocks, the Eos Aurora is a best-fit utility-grade solution for multi-hour, high-throughput applications such as locational capacity, peak shaving and renewable integration. The Eos Aurora integrates the company’s proprietary zinc hybrid cathode Znyth battery into an outdoor-rated, plug-and-play Energy Stack which enables rapid installation and reduces cost throughout the project lifecycle.

As a DC system supplier, Eos partners with major integrators through its Aegis program to deliver and install turnkey energy storage solutions. Aegis partners provide power conversion and controls, grid connection, and installation services as well as maintenance and warranty administration over the life of the project. Eos recently announced partnerships with Siemens and Northern Power Systems to deliver fully-integrated energy storage solutions, and is building out its Aegis program to offer and support deployments in markets around the world.

The Eos Aurora has no moving parts and employs widely available materials and highly commoditized manufacturing equipment and processes.
