Eos announces two projects deploying its Aurora battery system

By Editor


Eos Energy Storage (Eos) announced two new projects deploying the company’s Aurora 2.0 battery system in markets on both coasts of the United States.

First, Duke Energy has deployed the Eos Aurora 2.0 battery system as part of a DC-coupled solar + storage system in North Carolina.

Second, 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,” said Philippe Bouchard, Eos’ SVP of Business Development.

Duke Energy is commissioning a 30kW/120kWh system at its McAlpine test facility in North Carolina. Duke Energy has directly integrated, or DC-coupled the battery, to a grid-connected solar array using a DC-DC converter instead of an AC-inverter to reduce efficiency losses.

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

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 project contracted by developer Convergent Energy + Power with Pacific Gas & Electric. Eos is the only non-Lithium energy storage technology contracted through California’s procurement mandate AB2514.

“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 Byron Washom, UCSD Director, Strategic Energy Initiatives.
