Eos Energy Storage’s Aurora Battery System Commercially Available In 2016, At $160/kWh

January 29th, 2015 by  

Eos Energy Storage will be making its megawatt-scale Aurora system commercially available starting in 2016 at a price of $160/kWh, according to a recent press release.

The company’s standard offering, the Aurora 1000|4000 product, is a containerized 1 megawatt (MW) DC battery system that can provide roughly 4 hours of continuous discharge — thereby representing a fairly cost-effective energy storage solution that’s competitive with gas-peaking generation and/or conventional utility distribution.

“This system represents the culmination of many years of development and collaboration with our Genesis Partners to design a product with a clear value proposition,” stated Eos CEO Michael Oster.

The Aurora system makes use of Eos’s Znyth battery technology — based on a “non-toxic” aqueous electrolyte + novel zinc-hybrid cathode — to offer customers a low-cost energy storage system that possesses a long working life.

Some details via a recent press release:

As Eos’s manufacturing capacity ramps up, the company expects to deploy an aggregate of 1 MW of capacity over a series of projects in 2015, beginning with Consolidated Edison and GDF SUEZ, and including a project with Pacific Gas & Electric funded by the California Energy Commission.

The Aurora system’s commercial availability will improve the competitiveness of developers bidding into the PG&E and SCE solicitations due this quarter.


“A large number of inquiries regarding the California storage opportunities prompted us to make this announcement,” noted Eos President Steve Hellman. “We believe in full transparency around availability and pricing; we hope in this manner to provide the best product and the best value to our partners and customers.”

As of right now, the company is partnering through its “Aegis Program” with a number of large companies — Toshiba, Gamesa Electric, etc — to sell, install, and maintain its AC-integrated battery systems.

“We’re delighted to work with some of the largest suppliers of utility equipment in the world to provide the lowest cost turn-key energy storage solution in the market,” stated Hellman. The program is structured such that Eos supplies the containerized DC battery and battery management system while the Aegis Partners provide the power control systems and integration layer, and take responsibility for installation, operation, and maintenance.
