Product Description
®
The Eos Aurora 1000 | 4000 is a low-cost DC battery system designed specifically to meet the
requirements of grid-scale energy storage. With 4 hours of continuous discharge capability, immediate
response time, and modular construction, the Aurora system can be scaled and configured to reduce
cost and maximize profitability for utilities, project developers and industrial end-users.
Each sub-system includes pre-integrated strings of Eos batteries with DC wiring, DC system protection,
support structure, enclosure and a Battery Management System (BMS).

Peak-shaving and demand management
Utilities and end use customers can use Eos
batteries to store excess efficient base-load
generation and renewable energy produced
off peak. By discharging during peak hours,
Eos obviates the need for new dirty,
inefficient peaking generation, and reduces
carbon emissions.

Renewable Integration, Solar/Wind TimeShifting
Renewables such as wind and solar are
intermittent, potentially introducing instability
into the grid and limiting their viability as a
firm, dispatchable power source. Eos batteries allows utilities and consumers to smooth
production and time shift renewable energy.
Solar electricity produced at noon can be
stored and deployed as a stable power
source at peak demand in the afternoon.

Frequency Regulation
Eos batteries can be used to bring revenue to
our commercial and industrial customers. Eos
batteries are eligible for entry into ancillary
electricity markets that provide frequency
regulation to the power grid. By charging and
discharging your batteries to meet grid
stability, you can also monetize your asset.
