eos-270x185Eos 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.

    This is awesome news. Additional info from their web site:
    10,000 cycle, 30 year life. 75% round trip efficiency. And 12c-17c cost per delivered kWh.

    Those PV owners in Australia not on a generous gross feed in tariff are charged ~30c/kWh for electricity, but receive less than 10c/kWh for exports. Any battery with economics of less than 20c/kWh can take advantage of this pricing gap, and the owner will come out ahead. Retailers are certainly going to have to change their pricing soon, before EOS or some other company comes out with a residential sized battery with these economics.

      I installed solar last year and thus only qualified for an 8 cent fit. I knew this and was not overly concerned as I am mainly concentrating on using my system for self generation. Latest is that the fit will fall to 6.2 cents and the daily access charge rises by 24%!

      We have NO voice and no real influence in this and not helped by the pro-incumbent stance of most state governments and the captured Abbott regime (refuse to dignify them with the term “government”).

      I look forward to the cost of battery storage falling substantially for the home consumer as well as large scale storage. I do not see leaving the grid will be attractive to me in southern Victoria but some storage to avoid having to use the grid for some after sun set use looks to be attractive before much longer.

    Looking forward to it…Beats the hell out of a _ony 1.2kWh Lithium storage unit (8000 cycles to about 75% capacity retention) at wholesale price of $1933.79 – that’s $1611.49 / kWh .. And that doesn’t include the Battery management module, or the inverter/ charger, or installation.
    The real world price of quality gear has a long way to fall before anybody will be leaving the grid with 3 days of autonomy, in an affordable way. Exciting though…..

      Yes the prospects are very encouraging but aside from early adopters storage is not yet financially attractive to make consider adding storage to my solar system.

      My daily network access charge is going up some 24% from February. If this continues the fossilised electricity suppliers will drive people with solar off grid. I don’t think that would be a good development. Far better to have as many people stay connected.

    The worst bit of info to come out of this thread is yet another rise in the network access charge. What is going on is sheer market destruction. If rises like this are allowed (and it’s gone on for years now) it will make little difference using more or less electricity as the bill will be biased more by the TIME you’re connected to the grid, NOT the electricity used! Total lunacy. This is what removes incentive to reduce consumption. Consumers can reduce power consumption but reducing the days connected is a bit harder! Grid departures by those who can are thus hardly surprising, thus increasing the load on everybody else remaining. Pressure to jack up the network access charge then repeats itself. This long term “market myopia” has been brought to you by BOTH sides of politics and this debacle represents politics of the most harebrained (and well insulated from fiscal pain) sort. Not an effing clue! Determinedly stupid. Fick. You’d think even a current prime minister (and cabinet) could possibly understand.
