Eos Energy Storage Deploys Aurora 2.0 Battery System Coast to Coast with Duke Energy and University of California, San Diego

EDISON, N.J.–(BUSINESS WIRE)–Today, Eos Energy Storage (Eos) announced two new projects deploying the
Company’s Aurora 2.0 battery system in major markets on both coasts of
the United States. The next generation solution integrates the company’s
aqueous, zinc Znyth® battery technology—built on ten years of
relentless testing and learning—as a safe, sustainable, and scalable
alternative to Lithium Ion. The Eos Aurora® 2.0 has been
installed by Duke Energy as part of a DC-coupled solar + storage system
in North Carolina while Eos concurrently deploys its battery as a
behind-the-meter solution at the University of California, San Diego in
a project funded by the California Energy Commission.

“These two projects represent an important step in our journey to help
accelerate clean energy while ensuring that it is competitive and
reliable. With over ten years of testing and refinement, these
deployments demonstrate that our system is ready to scale in two of the
fastest growing renewable energy markets in the world,” said Philippe
Bouchard, Eos’ SVP of Business Development.

In North Carolina, one of the fastest growing solar markets in the U.S.,
Duke Energy is commissioning a 30kW/120kWh system at its McAlpine test
facility. The battery has been directly integrated, or DC-coupled, to a
grid-connected solar array using a DC-DC converter instead of an
AC-inverter to eliminate unnecessary hardware and reduce efficiency
losses. Because the Eos system does not require HVAC or fire
suppression, it can be decentralized and distributed throughout the
solar array allowing developers to maximize energy production while
minimizing upfront capital cost and O&M.

“With $500 million of battery storage projects slated for the Carolinas
over the next 10 years, Duke Energy is actively deploying the technology
in our communities as a way to enhance reliability, defer system
upgrades and deliver operational benefits for all customers,” said Tom
Fenimore, Business Development Manager at Duke Energy.

Meanwhile, California continues to surge forward to 60% renewable
electricity by 2030, 100% clean electricity by 2045, and 2GW of
near-term storage procurement. The deployment at University of
California, San Diego will demonstrate the Eos Aurora’s multi-hour
discharge capability as a means to reduce demand charges and manage
retail energy consumption for commercial and industrial customers. The
system provides 30kW/120kWh as a modular, AC-integrated, plug-and-play
solution optimized for behind-the-meter applications. The project also
prepares Eos for delivery of a larger 10MW/40MWh utility-scale project
contracted by developer Convergent Energy + Power with Pacific Gas &
Electric. To date, Eos is the only non-Lithium energy storage
technology contracted through California’s statewide procurement mandate

“As a national site host for laboratory and field testing of innovative
and unique energy storage system for a rapidly growing and important
market, UC San Diego looks forward to testing of the CA Energy
Commission project with Eos,” said UCSD Director, Strategic Energy
Initiatives Byron Washom.

Both projects are installed and undergoing commissioning; they will be
monitored to test the Aurora 2.0 performance in different use cases and
operating conditions.
